security camera improperly installed

What’s Wrong Here? Hint: Camera Enclosure Catastrophe

Think you know how this installation violates the NEC?

Hint: Camera enclosure catastrophe

I discovered this contraption during renovations to an apartment building lobby. This camera was hidden behind a piece of oak attached to the front of this wooden box mounted on the lobby ceiling. There was a hole cut in the oak for the camera to provide the tenants a view of the foyer and lobby on the TV in their apartment. Whoever provided power for the camera did not even bother to put the receptacle in a box. They simply connected the duplex receptacle directly to the NM cable conductors. Not installing a box for this receptacle is a violation of Sec. 300.15. You may also notice the giant hole bashed through the wall where the NM cable passes through. This is a violation of Sec. 300.21. Openings through fire-resistant-rated walls must be firestopped using approved methods that maintain the fire resistance rating of the wall. The lack of any supporting and securing of the NM cable is a violation of Sec. 334.30.
