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. Can you identify the specific Code violation(s) in this photo? Note: Submitted comments must include specific references from the 2017 NEC.

FEBRUARY WINNERS
This month’s winners were: Adam Stapleton, an electrical engineering specialist for Strang, Inc., in Madison, Wis.; Mark Sefira with CFM Commercial HVAC, Inc., of Orwigsburg, Pa.; and Valerie Muszynski with Southern Electric of Hartford, Conn. They all knew that securing cables to the exterior of raceways was not the correct method for supporting those cables.
Section 300.11(C) generally prohibits using raceways as a means of support for cables unless the cables are for Class 2 circuits used for controlling equipment that is powered by the circuit conductors in the raceway connected to that equipment. Raceways could support cables where the raceway is identified for that purpose, but PVC conduit is not made for this purpose. Section 800.133(B) also prohibits communication wires and cables from being attached by any means to the exterior of raceways as a supporting means.
Another concern with this installation is the possible lack of support for the PVC conduit itself. Section 352.30(A) requires this conduit to be securely fastened with 3 ft of each installed conduit body, box, or other conduit termination. Lastly, the yellow NM cable installed under this deck is a violation of Sec. 334.12(B), because NM is not permitted in this outdoor damp location.
