In regards to commercial occupancies, what equipment needs to be wired on the line side of the service switch besides the fire pump and the fire command station. I have a situation where i need to supply emergency power to an existing ats that is feeding a smoke purge system and an ats that is feeding stair way and corridor lightning.
Right now the generator has a 1200a main that feeds a MDP and the fire pump and command station are tapped before the breaker.
Do I need to do the same for the ats switches I need to wire or can I come right off the Mdp which would be much easier for me.
I'm not exactly clear what needs to be wired before the main service switch besides the pump and command station
