Question:
You are going to install a medium-base screw-shell lampholder at a distance of 14' above a floor and supply it with a 277v (nominal, to ground) circuit, will this be a correct installation?
A
Answer:
Section 210-6(c) lists the ways a 277v (nominal, to ground) circuit may be applied to lighting and supplying a medium-base screw-shell lampholder isn't one of them, the distance of 14' above the floor has nothing to do with it.
