What’s Wrong Here? Hint: Duct Tape to the Rescue

Aug. 11, 2021
Think you know how this installation violates the NEC?

No amount of duct tape can fix this mess. I am assuming the raceway laid on the ground between the parking lot pole lights was a temporary fix for some broken underground wiring. Unfortunately, the raceway has gotten damaged and broken away from the pole.

Section 110.12(B) prohibits damaged parts that may adversely affect the safe operation and mechanical strength of the equipment. The broken metal raceways are not mechanically joined to the pole as required by Sec. 300.10 to provide effective electrical continuity. The broken raceway also brings into question whether an effective ground-fault current path exists per Sec. 250.4(A)(5).

I think the time has expired for this temporary fix; it’s time to make some permanent repairs here.
