Getting to the Heart of NEC Listing Requirements
Does electrical equipment need to be listed? This is a question that practitioners have asked recently of NFPA and it’s one that comes up on a regular basis. Today, communication is dominated by social media and online forum discussions and as a result, people say they are having an increasingly difficult time determining what is required to be listed and what is not.

In his latest NEC column for NFPA Journal, author Derek Vigstol gets to the heart of these misconceptions and tackles that one important question everyone seems to be struggling with: What does it really mean for something to be “listed”?
