I own a 6 family apartment building in Brooklyn, and the electric was upgra ded back in 2000. I noticed on these panels in the basement, the feed coming straight from th e meter to the panel, there is no main disconnect. Only way to disconnect t he electric to the apt is to shut off the individual breakers ( see pic), or in the more recent renovations, shut off the main breaker in the baseme nt panel feeding the sub-panel in the apartment.
(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.
