(Only the 2 apartments on the first floor do not have a sub-panel within t he apartment). All of the panels in the basement are main lug. There is a main 200A disconnect for the entire building.
Is this correct? Isn't it necessary to protect the wiring or provide a mea ns of disconnect from the meter to the panel?
I'm asking because we are doing a bathroom reno on the first floor, and I r an a new 12/2 BX just for the bathroom. And when I installed in the panel, to be safe I wanted to de-energize the entire panel, but the only way to do that was to turn off the entire building.
I managed to install it anyway while the panel was live.
