What’s Wrong Here? Hint: A Double Whammy

June 16, 2016
Think you know how this installation violates the NEC?

How well do you know the Code? Think you can spot violations the original installer either ignored or couldn't identify? Here's your chance to moonlight as an electrical inspector and second-guess someone else's work from the safety of your living room or office. It's your turn to identify the violation.

Hint: A double whammy

Find the Answer

Not only is this storage cabinet blocking ready access to this panelboard and its circuit breakers, but flammable liquids are also being stored in this room as well. This is a really dangerous combination of problems. The working space for the panelboard is not permitted to be used as storage space for anything, especially flammable liquids!

Section 110.26(B) states very clearly that this working space area cannot be used for storage. Unfortunately, this is an all-too-common violation. Section 240.24(A) requires overcurrent devices (such as circuit breakers) to be located so as to be readily accessible. The definition of “readily accessible” from Art. 100 means capable of being reached quickly for operation or inspections without the need for using tools or to remove obstacles, or resorting to using portable ladders and so forth. I would say that this storage cabinet violates the intent of being readily accessible. If nothing else, it certainly elevates the danger by having flammable liquids being stored near equipment that may produce arcs or sparks, which also violates Sec. 240.24(D).
