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. Joe Tedesco, who has a knack for finding shoddy electrical work, did the dirty work and found this mess. Now it's your turn to identify the violation.

Something tells me that this installation doesn’t quite meet the intent of the installation requirements of 314.15. Don’t you agree?
Per 314.15(A), boxes, conduit bodies, and fittings installed in damp or wet locations shall be placed or equipped so as to prevent moisture from entering or accumulating within the box, conduit body, or fitting. In addition, the boxes, conduit bodies, and fittings installed in wet locations shall be listed for this use. And FPN No. 2 requires protection against corrosion as per the requirements of 300.6.
But that’s not the only violation evident here. The lack of electrical continuity of the metal raceway is also a problem. Per 300.10, metal raceways, cable armor, and other metal enclosures for conductors shall be metallically joined into a continuous electric conductor and shall be connected to all boxes, fittings, and cabinets so as to provide effective electrical continuity. Unless specifically permitted elsewhere in this Code, raceways and cable assemblies shall be mechanically secured to boxes, fittings, cabinets, and other enclosures.
