What is the danger with this type of installation?
Dennis Alwon said:I guess we are looking at 312.5(C). I have never quite understood this exactly. I would say this is legit if (b) is satisfied. I am not sure if that is penetrating a structural ceiling.
Of course I am not sure (c) or (d) is followed either
Needess to say it is done quite often.
Oh yeah-- minor details....oopsinfinity said:You missed the part about it being surface mounted. A recessed panel does not fall under the exception.
infinity said:Dangers? I see none, the NEC feels differently however.

Yeah, kinda no different than the fire traveling through a snap-in bushing into the wall.
