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: Disappearing act
In this photo, we see a PVC pipe secured to a pole. The PVC pipe itself has not been damaged by sunlight since it is constructed to be "resistant to sunlight effects" in accordance with 352.100. The clip, on the other hand, has been severely damaged by the effects of being in the direct rays of the sun for a prolonged period of time. The clip has become very brittle and has cracked almost completely through.
Hint: Disappearing act
This is a violation of 300.6(C), which requires nonmetallic raceways, elbows, couplings, fittings, supports, and support hardware to be made of material approved for the condition they are placed. These items shall also comply with 300.6(C)(1), which states "where exposed to sunlight, the materials shall be listed as sunlight resistant or shall be identified as sunlight resistant." The material that the clip was made of is clearly not sunlight resistant.
