Changes to Kitchen Island and Peninsula Receptacle Outlet Requirements for the Past Three NEC Editions

Requirements for kitchen island and peninsula receptacle outlets have been a part of the National Electrical Code® (NEC®) since the 1990 edition. At that time, 210.52(c) stated: “Island and peninsula counter tops 12 inches (305 millimeters) or wider shall have at least one receptacle for each four feet (1.22 meters) of counter top.” Over the course of the next 30-plus years, there were many significant changes made around island and peninsula receptacle outlet requirements within the NEC. Perhaps no changes to these requirements represented a larger swing of the pendulum than those we have seen over the past three cycles: the 2017, 2020, and 2023 NEC.   2017 NEC Requirements   The following are the relevant sections and requirements for island and peninsula receptacle outlets based on the 2017 NEC. They have been paraphrased in this blog. ·       210.52(C)(2) and 210.52(C)(3) require at least one receptacle to be installed at each island or peninsula having a countertop with a long dimension of 24 inches (600 millimeters) or greater and a short dimension of 12 inches (300 millimeters) or greater. o   The peninsula countertop dimension is measured from the connected perpendicular wall. ·       210.52(C), Exception to (5) allows for receptacle outlets to be mounted a maximum of 12 inches (300 millimeters) below island and peninsula countertops and work surfaces as long as they are not located where the countertop or work surface extends more than 6 inches (150 millimeters) beyond its support base, in either of these two scenarios: o   Where the construction is for the physically impaired. o   On island or peninsula countertops or work surfaces where the surface is entirely flat (e.g., no backsplash) and has no means to mount a receptacle within 20 inches above the countertop or work surface, such as on an overhead cabinet. One of the significant changes between the 2014 and 2017 NEC requirements was in 210.52(C)(3) addressing peninsular countertop spaces. In the 2014 NEC, the peninsular countertop was required to be measured from the “connecting edge,” which was then changed to measuring from the “connected perpendicular wall” in the 2017 NEC. In the 2017 NEC, 210.52(C), Exception to (5) was revised to also include “work surfaces” as being a part of the requirement, along with countertops. This is consistent with changes in other areas within 210.52 of the 2017 NEC that added the term work surfaces, including changing the title of 210.52(C) to “Countertops and Work Surfaces.”   2020 NEC Requirements   In the 2020 NEC, island and peninsula receptacle outlet requirements saw a major overhaul from those in the 2017 NEC. Where the 2017 NEC required at least one receptacle outlet to be installed in islands and peninsulas with a long dimension of 24 inches or greater and a short dimension of 12 inches or greater, there was never a scenario that required more than one receptacle outlet to be installed in these locations. Changes to the 2020 NEC required at least one receptacle outlet to be installed in all islands and peninsulas, and potentially more depending on the overall square footage of the countertop or work surface for the island or peninsula. Here is an overview of the changes to 210.52(C) in the 2020 NEC (paraphrased): ·      210.52(C)(2) has been revised to cover both islands and peninsulas and has added the following requirements: o   At least one receptacle outlet must be installed within an island or peninsula for the first 9 square feet (0.84 square meters), or fraction thereof, of the countertop or work surface. o   An additional receptacle outlet must be installed within an island or peninsula for each additional 18 square feet (1.7 square meters), or fraction thereof, of the countertop or work surface. o   At least one receptacle outlet must be installed within 2 feet (600 millimeters) of the outer end of a peninsula countertop or work surface. o   Additional required receptacle outlets are permitted to be located as determined by the installer, designer, or building owner. o   A peninsula countertop must be measured from the connected perpendicular wall. o   The location of the receptacle outlets must be in accordance with 210.52(C)(3). The picture below depicts a 3-foot by 8-foot island. Based on changes to the 2020 NEC, the first 9 square feet (represented by the light blue area) require a receptacle outlet to be installed. That leaves a 3-foot by 5-foot area remaining in the yellow area. That area totals 15 square feet, therefore falling into a fraction of an additional 18 square feet and requiring an additional receptacle on the island, for a total of two. The locations that these two receptacles are installed must be done in accordance with 210.52(C)(3).   For the 2020 NEC, 210.52(C)(3) was revised to cover receptacle outlet locations, which were previously covered in the 2017 NEC by 210.52(C)(5). Revised 210.52(C)(3) provides three different list items identifying where island and peninsula receptacles are permitted to be located (paraphrased): 1.     On or above countertop or work surfaces, but no more than 20 inches above. 2.     In the countertop or work surface using a receptacle outlet assembly that is listed for the application. 3.     Where installed not more than 12 inches below the countertop or work surface and not located where the countertop or work surface extends more than 6 inches beyond its support base. Receptacle outlets that are not readily accessible or are located in assigned spaces for appliances within the peninsula or island (e.g., dishwasher, mini fridge, etc.) are not permitted to count as the required receptacles outlets for the island or peninsula.   2023 NEC Requirements   Section 210.52(C)(2) saw extensive revisions between the 2020 and 2023 NEC. All of the requirements around receptacle outlets being installed based on the square footage of the countertop and work surface of islands and peninsulas were removed. Perhaps more significant, the requirement for any receptacle to be installed within islands and peninsulas was removed. You read that right: No receptacle outlet is required to be installed within islands or peninsulas based on the 2023 NEC—with a caveat. The revisions to 210.52(C)(2) in the 2023 NEC essentially changed island and peninsula receptacles to have two requirements (paraphrased): 1.     Receptacle outlets in islands and peninsulas, if installed, must be done in accordance with 210.52(C)(3). 2.     If a receptacle outlet is not provided for islands and peninsulas, provisions must be provided for the addition of a receptacle outlet in the future. Note: The means by which the provision is made for a future receptacle outlet is not stated by the NEC; therefore, the authority having jurisdiction (AHJ) will need to be consulted to determine what they will consider as meeting this requirement.   Watch a related video from the NFPA LiNK® YouTube channel Section 210.52(C)(3) has also been revised for the 2023 NEC, essentially to provide the following three options for where island and peninsula receptacle outlets can be installed (paraphrased): 1.     On or above countertop or work surfaces, but no more than 20 inches above. 2.     In a countertop using a receptacle outlet assembly listed for use in countertops. 3.     In a work surface using a receptacle outlet assembly listed for use in work surfaces or listed for use in countertops. What can be noted as a major change in the 2023 NEC from the receptacle outlet location options for islands and peninsulas in 210.52(C)(3) of the 2020 NEC, is the ability to install receptacle outlets below countertops and work surfaces. Receptacle outlets for islands and peninsulas are no longer able to be installed below the countertop and work surface level. As part of its substantiation for the change, NEC Code Making Panel 2 cited Consumer Product Safety Commission (CPSC) data showing that between 1991 and 2020, an estimated 9,700 people, many of them children, were treated in United States emergency departments for burns and other injuries after pulling on or running into power cords plugged into receptacle outlets installed below island and peninsula work surfaces.  Those who opposed the change, however, cited accessibility concerns. Because of this change, as well as other changes to 210.52(C)(2) and (C)(3), the 2023 NEC essentially provides three options for island and peninsula receptacle outlet installations, or non-installations, as depicted in the bullet points and photo below: ·      Option 1 permits the installation of receptacle outlets above the countertop or work surface, but not more than 20 inches above. Islands and peninsulas with elevated backsplashes present an opportunity for using this option. ·      Option 2 permits installation of receptacle outlets within the countertop or work surface, provided a receptacle outlet assembly listed for the application is utilized. ·      Option 3 is utilized when no receptacle outlet is installed within the island or peninsula. In that case, the 2023 NEC requires a future provision to be made where a receptacle outlet could be installed at a later date. The junction box with protective flexible conduit for the NM-B cable is just one example of how this could possibly be done, but it is not required to be done this way per the 2023 NEC.     Change and the NEC are practically synonymous. But it is rare that we see such drastic changes in requirements within the same section of the NEC over such close cycles. Personally, I believe that these changes show how important it is for the public to get involved in the NFPA® standards development process. Whether you’re an individual with relevant data that you can provide or an electrician that has an idea of what should change, the safety that the NEC provides depends on your input. I encourage everyone to learn more about the standards development process to get involved.

Growth in Codes and Standards is Essential to Safety within Cannabis Oil Extraction Facilities

Both the cannabis plant and the industry itself have been growing quite a bit over the past decade. In 2012, Colorado and Washington became the first two states to legalize recreational use of cannabis. Many other states followed suit. As of November 2022, a total of 21 states, and the District of Columbia, had approved the use of cannabis for recreational purposes. Legalization provided many people with an opportunity to use cannabis to treat conditions such as pain, migraines, depression, and anxiety, among other things, while remaining law-abiding citizens. With the increase in demand came a need for an increase in supply. Facilities of all shapes and sizes began popping up in states where cannabis was legalized to be manufactured. While cannabis is commonly smoked by many users, other forms of cannabis products include gummies, oils, supplements, and extracts. These products are manufactured by extracting cannabidiol (CBD) and tetrahydrocannabinol (THC) from the plant itself. What are the safety concerns? The extraction of cannabis oil can pose many safety issues, including the risk of fire and explosion. In many cases, the extraction process itself creates a hazardous location due to the use of flammable solvents such as butane, pentane, hexane, propane, and ethanol, which can all be released during the processing and extraction of plant oils. Proper installation, maintenance, and use of the extraction equipment employed as part of the processing of oils from cannabis will go a long way in achieving overall safety within these types of facilities.   RELATED  • Listen to an NFPA podcast about regulating the cannabis industry • Read, “The New Face of Pot,” published in the July/August 2018 NFPA Journal     What does the NEC say?   The 2023 edition of NFPA 70®, National Electrical Code® (NEC®), made significant strides toward helping achieve electrical safety in facilities that perform cannabis oil extraction by adding Article 512, Cannabis Oil Equipment and Cannabis Oil Systems Using Flammable Materials.   This new article provides electrical requirements for cannabis oil preparatory equipment, extraction equipment, booths, post-processing equipment, and systems using flammable materials (flammable gas, flammable liquid–produced vapor, combustible liquid–produced vapor) in commercial and industrial facilities. A public input that was submitted for the 2023 NEC as part of the NFPA standards development process, PI-2285, supported creating a new article that would “elevate the level of safety” within the cannabis industry. The substantiation of PI-2285 provided examples of real-life explosion incidents within cannabis facilities, some of which required more than 200 firefighters to battle the blaze and left large numbers of firefighters injured. In an industry that has processes and procedures unfamiliar to many authorities having jurisdiction (AHJs) and that continues to see tremendous growth, it is crucial to provide safety requirements around installations that can be verified at the time of inspection.   While it is likely that we will see new Article 512 expand within future NEC cycles to provide more guidance, the initial content contained within the 2023 NEC begins to provide some of the necessary requirements for designers, installers, and AHJs to achieve electrical safety around cannabis equipment and systems.   Article 512 is broken down into three parts: Part I: General; Part II: Wiring; and Part III: Equipment. Section 512.3 is a key component for installations as it provides the requirements for how cannabis oil equipment and systems that can release flammable materials during operation must be classified. The section is broken down into Part A, which covers installations outside of booths, and Part B, which covers installations within booths. Each of these areas are then further broken down into installations where flammable gases and vapors are released and installations where flammable gases and vapors are not released.   Having the area classified properly is an important initial step as we move into Parts II and III of Article 512 to determine how wiring and equipment installations must be performed in and around the hazardous locations. Part III, in particular, includes requirements for the equipment and systems to be listed and marked. It also provides guidance on when gas detection is required. While the new Article 512 within the 2023 NEC is a great starting point for beginning to provide electrical safety requirements within cannabis facilities, as can be expected, safety needs don’t stop there. A new, dedicated cannabis standard Currently, NFPA is in the development stages of NFPA 420, Standard on Fire Protection of Cannabis Growing and Processing Facilities. The overall goal of NFPA 420 is to address the protection of facilities where cannabis is being grown or processed from fire and related hazards. Initial meeting minutes found at the NFPA 420 document information page reflect committee task groups working to develop preliminary chapters that provide information pertaining to fundamentals, indoor growing, drying/processing, and extraction. Provided that the draft development progresses at the technical committee level, and approval to do so is provided by the NFPA Standards Council, the goal is to have an initial NFPA 420 document available for public input sometime in 2024. The growth of the cannabis industry does not show any signs of slowing down. A recent article in Forbes stated that market research firm BDSA is forecasting cannabis sales in the United States to grow from $25 billion in 2021 to $40 billion in 2026. More facilities, more processing, and more workers lead to an increased need for safety within the cannabis industry. Continued development of codes and standards that provide knowledge for those designing, performing, and inspecting these installations is paramount to achieving a high level of safety within cannabis growing and processing facilities.

Electrical and Fire Safety Considerations At Home During the Cold Winter Months

Looking outside your window at the dropping thermometer or stepping outside to be met by the brisk air are both reminders that it is time to dig the snow shovels and snowblowers out of the back of the garage. Being an electrician, when I think about home responsibility and safety during the wintertime, my natural tendency is to look at it from an electrical perspective. But as  a homeowner, I also need to be considerate of best practices around fire safety. Changes to what we do outside and inside of our homes through the winter months present both electrical and fire safety risks that can be properly managed by both awareness and following the proper code requirements, in all codes that apply. As we transition into these winter months, there are requirements in both the NFPA 1 Fire Code and NFPA 70® National Electrical Code® (NEC®) that must be followed to ensure the safety of your home. Winter just wouldn’t be winter without holiday lighting. Ensuring that the holiday lighting is listed and, where installed outdoors is rated for the application, is a great start. But often, the outdoor holiday lighting masterpieces installed in the coming months are also inclusive of extension cords and relocatable power taps (more commonly known as “power strips”) as well. As was the case with holiday lights, extension cords and relocatable power taps should also be listed and rated for the environment in which they are installed. Improper use of any or all of these components within holiday lighting not only has the ability to pose an electrical safety risk to the home, but a fire safety risk as well. NFPA 1 has code requirements, which are also relevant when it comes to electrical installations, that apply to both extension cords and relocatable power taps. Some of those NFPA 1 requirements being: Extension cords shall be plugged directly into an approved receptacle, power tap, or multiplug adapter and shall, except for approved multiplug extension cords, serve only one portable appliance. [1:] Extension cords shall be maintained in good condition without splices, deterioration, or damage. [1:] Extension cords and flexible cords shall not be affixed to structures; extend through walls, ceilings, or floors, or under doors or floor coverings; or be subject to environmental or physical damage [1:] Relocatable power taps shall be listed to UL 1363, Relocatable Power Taps, or UL 1363A, Outline of Investigation for Special Purpose Relocatable Power Taps, where applicable. [1:] The relocatable power taps shall be directly connected to a permanently installed receptacle. [1:] Relocatable power tap cords shall not extend through walls, ceilings, or floors; under doors or floor coverings; or be subject to environmental or physical damage. [1:] When looking at the way a typical holiday lighting installation may be performed by those that may not be aware of these safety requirements, there are several things that stand out. Extension cords are not permitted to be plugged into other extension cords, rather they should only be plugged into an approved receptacle, power tap, or multiplug adapter. Because extension cords must be in good condition and free from damage, that rules out the extension cord that got caught up in the hedge trimmers during the summer and now has the damaged area wrapped in electrical tape. Relocatable power taps cannot be “daisy chained” by plugging into other relocatable power taps; they can only be plugged directly into a permanently installed receptacle. Both extension cords and relocatable power taps are not permitted to be installed where subject to environmental or physical damage. Furthermore, extension cords are not permitted to be affixed to structures, such as homes.   One area where both NFPA 1 and the National Electrical Code® (NEC®) align in their requirements is around the timeframe that holiday lighting can be installed. NEC section 590.3(B), which is directly referenced in NFPA 1 section, states that holiday lighting cannot be installed for more than 90 days. So, for individuals who get really excited about the holidays and install their holiday lights in early October, that means they will need to be taken down close to the first of the year to meet the 90-day requirement. Also from an NEC perspective, it is critical to ensure that all of your exterior holiday lighting is plugged into a GFCI receptacle that has been tested to be functional and working properly.   When the temperature in the house falls, the heat comes on. While likely the most common, gas-forced air furnaces are not the only way in which a home is heated. Boilers, heat pumps, and electricity are also utilized to heat homes. From an electrical perspective, electric furnaces, baseboard heat, plug-in space heaters, and electric fireplaces may also be utilized. With electrical equipment that is utilized to produce heat, it is important to understand that it puts a tremendous load on the electrical system. Circuits that operated normally throughout other parts of the year can now become overloaded when heating items, like portable space heaters, are plugged in during the winter months. When it comes to portable space heaters, it is also important to note that while it is heating your space, you need to maintain space between the heater and any combustible materials. In a home heating fires report published by NFPA in January 2021, fixed and portable space heaters were responsible for 81 percent of civilian deaths. That number is overwhelming considering the next closest equipment responsible for civilian deaths were fireplaces and chimneys at nine percent.   Because of the changes in the way homes are used when the cold weather sets in, both electrical and fire safety must be evaluated based on the change in use.  As we move into these chilly months, it’s important to stay keenly aware of the changing environment and implement the safety measures that are necessary to keep your home safe. Winter is coming… Please visit the NFPA public education page for more information on how to keep your home safe this winter and throughout the rest of the year.

Electrical Safety Tips for Users of E-Bikes and E-Scooters

A version of this article will appear in the In Compliance section of the Winter 2022 issue of NFPA Journal.  Recent discussions around electric micromobility devices, such as e-bikes and e-scooters, have left a lot of people rather charged up. Proposed changes by the New York City Housing Authority (NYCHA), for example, would prohibit residents and guests from keeping e-bikes or e-scooters within NYCHA apartments or building common areas. Delivery workers have raised concerns that such a ban would adversely affect their livelihoods, since charging the e-bikes that they use to make deliveries would no longer be possible in their homes.  Watch a related video on e-bike and e-scooter fire safety Big cities aren’t the only places where authorities have moved to ban e-bikes or e-scooters from buildings. Mackinac Island, a small vacation island in northern Michigan, has become well-known for regulating the means of transportation that are permitted on the island. Since 1901, automotive transportation has been banned, leaving most travel to be done on foot, by bicycle, or by horse and carriage. Not long ago, island authorities banned e-bikes within certain buildings and have further prohibited the use of e-bikes that have functional throttles when traveling around the island. (For an overview of the safety hazards associated with electric micromobility devices and the regulations proposed to address those hazards, see “Full Throttle,” a feature story that appeared in the Fall 2022 issue of NFPA Journal.) SAFETY RESOURCES: Visit to explore other NFPA resources related to e-bike and e-scooter fire safety Improving e-bike and e-scooter safety is providing much of the momentum behind these changes. In 2022 alone, the Fire Department of the City of New York (FDNY) has reported investigating 130 fires related to lithium-ion batteries regularly used to power e-bikes—fires that have resulted in five deaths and dozens of injuries. In October, the Consumer Product Safety Commission (CPSC) recalled about 22,000 e-bikes whose “lithium-ion batteries can ignite, explode, or spark, posing fire, explosion, and burn hazards to consumers,” CPSC wrote in a statement. Investigators say a fire that killed an 8-year-old girl in Queens last month was likely ignited by an e-bike battery charging inside an apartment unit overnight. A fire in December 2021 killed a New York City man who was running a business charging e-bikes within his residence. Two teenagers narrowly escaped the same fire themselves by shimmying down a pipe mounted to the building’s exterior wall. Over the summer on Mackinac Island, an e-bike battery that exploded and melted left both the homeowner and firefighters with injuries related to smoke inhalation. In all of these cases, the personal decisions made by individuals to charge e-bikes in their homes left others in harm’s way. While there are no specific codes in place for the charging of e-bikes or e-scooters themselves, there are portions of codes, including NFPA 70®, National Electrical Code® (NEC®), that can help people be safer while doing so. There are also additional areas that can be addressed to further ensure safer charging.  Avoid overloading circuits and overcharging batteries Electricity is necessary to charge e-bike batteries, meaning the battery being charged and the device charging the battery can be potential fire hazards. An aspect that can sometimes be overlooked, though, is that the structural wiring within the building can be a risk as well. Ensuring that the electrical infrastructure in the building is properly installed and capable of delivering electricity for safe charging is where the NEC comes into play. If we consider the deadly NYC fire that killed the man who was charging e-bikes out of his residence, we can assume that overloading the circuit may have been part of the issue. When multiple e-bikes are being charged at once, the load on the circuit supplying power for charging increases. Another scenario that could have compounded the imposed load on the circuit is that it was a continuous load. The NEC defines a continuous load as one where the maximum current is expected to continue for three hours or more and requires any continuous loads to be factored in at 125 percent. As an example, a 20-amp circuit is only permitted to be loaded to 16 amps when continuous loads are involved (16-amp continuous load x 125 percent = 20 amps). With e-bikes being charged for over three hours and multiple e-bikes being charged simultaneously, the circuit could have easily been highly overloaded, which could have begun degradation of the wiring, causing it to eventually break down and become a possible ignition source. Furthermore, overcharging batteries is something that an individual can easily do without intending to, but it can have a catastrophic effect resulting in fires and death. Recently, Inside Edition released a video that shows the impact that overcharging batteries can have and how quickly micromobility devices can burst into flames because of it. It is crucial that individuals that are charging the batteries of micromobility devices follow the manufacturer’s instructions for proper charging and do not overcharge the batteries. Overcharging not only puts their own lives at risk but also the lives of many others. Look for listed devices, batteries, and charging equipment Another area that must be considered around e-bike charging safety is the product itself. Consumers should be sure that they are purchasing a high-quality product that has been listed by a nationally recognized testing lab and labeled accordingly. Part of the charger system evaluation is the plug-in charger itself. It is important for consumers to understand that the charger that comes with the e-bike is what gets tested as part of the listing and therefore is the only charger that should be utilized. Buying an aftermarket charger from another manufacturer could likely invalidate the listing of the e-bike and may contribute to the additional risk of a fire due to compatibility not being tested between the e-bike and the charger. There are many products out there that may be noted as compatible with an e-bike, but they may not be listed to work with a specific e-bike.  The importance of using e-bikes and products that are listed was echoed in July when Heather Mason, president of the National Bicycle Dealers Association, encouraged their vendors and suppliers to certify their e-bikes to UL 2849, Standard for Electrical Systems for eBikes. “The bicycle industry needs to take immediate action,” Mason stated at the time. “After extensive consultations with experts in the field, e-bike and e-scooter lithium-ion battery safety is a large and immediate subject that we need to act on now. The advisement statement we have prepared for retailers takes the interest of e-bike continued growth within the industry and safety for all. If we do not address the core issue, we may see this propel to something beyond our control.”    With the recently proposed bans on e-bikes getting many people charged up, it is important to consider that the authorities proposing these changes are doing so with public safety in mind. When improper and unsafe charging of e-bikes takes place, tragedy can follow. People who use e-bikes should continue to learn about the intricacies involved in safe charging. Doing so will not only impact their own personal safety, but the safety of their neighbors as well.

Amazon Solar Shutdown Provides Opportunity for Praise and Reflection on Safe Solar Installations

According to recent reports from CNBC and other major news outlets, Amazon temporarily shut down all solar power generation at their North American facilities last year as they worked to investigate potential fire safety issues with these systems. While the details of what Amazon found in their investigations during the shutdown are unspecified and therefore can’t be expounded upon, knowing that Amazon recognized a compounding problem and made safety paramount by shutting down their solar generation at 47 North American sites should be commended. Although there was significant financial loss to Amazon by moving forward with the shutdown and launching the investigation, making the decision to do so aligned with the principles established by the NFPA Fire & Life Safety Ecosystem™—specifically, the company chose to make an Investment in Safety. The NFPA Fire & Life Safety Ecosystem is a framework that identifies the components that must work together to minimize risk and help prevent loss, injuries, and death from fire, electrical, and other hazards. There are eight key components in the Fire & Life Safety Ecosystem. These components are interdependent. When they work together, the Ecosystem protects everyone. If any component is missing or broken, the Ecosystem can collapse, often resulting in tragedy. Almost always we can trace the cause of fire and life safety tragedies back to the breakdown of one or more components. Aside from the aforementioned Investment in Safety, there are several other key areas of the Ecosystem that apply to safe solar installations. Codes, compliance, and skilled workers With a technology that is constantly changing like solar photovoltaic (PV) power, using the most current codes is critical for a safe installation. Within the Ecosystem, this would fall under the Development and Use of Current Codes component. As an example, NFPA 70,® National Electrical Code® (NEC®), covers the installation of PV systems in Article 690, including the array circuit(s), inverter(s), and controller(s) for such systems. Article 691 covers large-scale PV electric supply stations not under exclusive utility control, such as privately owned solar farms. Yet many areas of the country do not use the most current edition of the NEC, with some areas using editions dating back as far as 2008. That is a 15-year difference between the most current NEC and some of the oldest versions being used. As can be expected, there have been significant changes in product development and safe solar installation requirements over those years. For instance, rapid shutdown is a means of solar equipment reducing the potential for electric shock within 30 seconds of activation of shutdown, intended to raise the level of safety for firefighters that are responding to potential solar array fires. Rapid shutdown was introduced in the 2014 cycle of the NEC so anyone utilizing prior editions would not be providing this level of safety for first responders. This is a clear example of why it is so important to utilize the most current codes for solar installations in order to achieve maximum safety.   Fortunately, even for jurisdictions that are lagging behind in the use of the most recent codes, professionals can choose to take trainings on more recent editions. The NFPA 70, National Electrical Code (NEC) (2020) Online Training Series, for example, provides trainees with key information and interactive exercises on the 2020 edition of the NEC. With the 2023 NEC having just taken effect September 1, be on the lookout for forthcoming training based on that version of the NEC.   Another area of the Ecosystem that is necessary for a safe solar installations is Code Compliance. The only way to truly ensure a safe installation is by verifying it through effective code enforcement. Those tasked with inspecting solar installations for safety must consider everything involved while reviewing the systems. NEC requirements as well as manufacturer installation requirements are critical items that must be met. It is also important to remember that code compliance does not end with the initial installation of the system. Any time a solar installation gets updated or modified, it is just as important to have that system reviewed again for continued compliance with the necessary codes as it was to have it inspected in the first place. The individuals that perform the solar installation matter as well. The Ecosystem requires a Skilled Workforce in order to ensure safe installations. Those that are considered skilled are aware of the most current codes and know how to apply them to the installation. They have been trained to properly handle, install, and maintain the equipment that is involved. From an enforcement standpoint, the NEC takes skill a step further by requiring that only qualified persons perform the installation of solar equipment, associated wiring, and interconnections. By definition within the NEC, a qualified person has skills and knowledge related to the construction and operation of the electrical equipment and installations and has received safety training to recognize and avoid the hazards involved. One critical way a Skilled Workforce can be created is through training programs like the ones offered by NFPA. The Photovoltaic and Energy Storage Systems Online Training Series, for example, is a four-part online program that covers topics that can assist with design, installation, maintenance, and inspection requirements for PV and energy storage systems. The training educates users on relevant code requirements for PV systems and ESS not just within the NEC, but also within other leading codes including NFPA 1, Fire Code, NFPA 855, Standard for the Installation of Stationary Energy Storage Systems, NFPA 5000®, Building Construction and Safety Code®, and others. When it comes to safe installations of solar power it is critical that we play offense, instead of defense. Choosing to be proactive by ensuring safe installations that align with the NFPA Fire & Life Safety Ecosystem up front will prevent the need for reactive decisions to correct any potential problems down the line. In the United States alone, solar power capacity has grown from approximately 0.34 gigawatts in 2008 to an estimated 97.2 gigawatts today. With no slowing down in sight, it is critical that those involved in performing solar installations and maintenance are doing so with safety as an important and necessary part of the process.

Now Issued, We Thank Those That Brought the 2023 NEC to the Top of the Mountain

It’s been a long climb to the top, but we made it – together! The NFPA Standards Council has voted to issue the 2023 National Electrical Code® (NEC®) with an effective date of September 1, 2022. With a pandemic overarching most of this revision cycle, we faced challenges never before seen in working through the NFPA Standards Development Process to create the 2023 NEC. A very special thanks goes out to the public for their valuable inputs and comments, the countless volunteer committee members for sharing their valuable time and knowledge, and NFPA staff for all of their hard work of governing the process and keeping everything on task through the challenges brought about by the pandemic. This truly has been an NEC cycle like none we have ever seen before. While there were new challenges along the way, it never delayed the development process which is rather inconceivable considering the way the world was being impacted by the pandemic. Not only did it not slow down, but it also increased. Every actionable item of the NFPA Standards Development Process increased in the 2023 NEC cycle versus the 2020 NEC cycle including: Public Inputs (PIs), First Revisions (FRs), First Correlating Revisions (FCRs), Correlating Notes (CNs), Public Comments (PCs), Second Revisions (SRs), Second Correlating Revisions (SCRs), and Certified Amending Motions (CAMs). After two years of not having our annual NFPA Conference & Expo in-person, 2022 allowed us to finally all get beck together in Boston for C&E in June where the Technical Meeting was held. During the meeting, the 55 CAMs for the 2023 NEC were presented and most were debated by membership on the meeting floor. The only CAMs that were not debated were those that were not pursued by the submitter, often due to the results of a previously debated CAM around the same topic failing to get the necessary votes from membership. In early August, the NFPA Standards Council heard fourteen appeals related to the 2023 NEC, which after the voting of the Council resulted in 18 amendments and four concurrently issuing Tentative Interim Amendments (TIAs). Some of the topics of the appeals that were heard dealt with optical fiber cable, copper-clad aluminum wiring, surge protection devices, GFCI protection, and swimming pool bonding. After all was considered, the preliminary minutes for the NFPA Standards Council Meeting concluded that the Council set an issuance date for the 2023 NEC as August 12, 2022, and the aforementioned effective date as September 1, 2022.   After the thrill of climbing the mountain, and all that was overcome, every good climber sticks a flag in the ground to celebrate their accomplishments. The mountain that we all climbed to reach the pinnacle of the 2023 NEC should be commemorated as well. Our distinctive flag in the ground for the 2023 NEC comes by way of NFPA LiNK®, which is NFPA’s digital access to codes and standards, plus so much more. All previous NEC code cycles always had a delay between when it was issued and when it was available due to the time it took for printing, but the 2023 NEC will be different. The 2023 NEC will become available in NFPA LiNK® on September 1, 2022. That’s right, if you are a subscriber to NFPA LiNK®, the 2023 NEC will be available to you on the same day that it becomes effective. For individuals that still prefer the book version of the NEC, the softbound, spiral, and handbook versions are available for preorder now and will become available this fall. The best view always comes when you reach the peak of the mountain. From what I can see, our ability to make electrical installations around the world safer just improved with the addition of the 2023 NEC. A very special thank you goes out to all of you that helped us to climb the mountain!
