A bit of a dispute here has came up and I was wondering if somebody could clarify. I was almost certain that an electrical closet needed to be labeled "Electrical Closet" or simular on the door for the given closet. In our case it is a bi-fold door with a disconnect, 208v panel, and timeclock/contactor. I have been trying to verify where I thought I read that in the code and I am at a loss..any help would be appreciated.
