Electrical room: we have 1,200A MLO distribution panel, this panel is protected by 1,000A CB in upstream panel.
Do we have to follow 110.26(c) rule so the room need to have two entrance doors? ... Or one entrance door if panel satisfy double clrearance requirement?
Since the panel is protected by 1,000A CB, we can consider panel rating is1,000A not 1,200A right? Then, we may need only one door for the room. I am not sure if panel is wider than 6', could be less than that. This will be another support factor?
