Ernie- I thought no one was going to give an opinion but alan was brave enough to start the ball rolling.
I just read 695.3 ('02 NEC) and what I get out of it is the key word "reliable" and if this system is "reliable" than there are some options that kick in. They are listed in 695.3. Knowing you you've already read them. If this is a "Required" fire pump and I'm sure it is, than Article 700 would kick in. The transfer switch and associated wiring needs to be installed in such a way to give priority to the fire pump. We are talking about load shedding and capacity as well as the isolation of wiring. I don't have NFPA 20 but I'm sure some Engineer on this BB will join in and help us. Kinda a "straddle the fence answer but then, I'm not a fire pump expert by any means. See Ya in September as well as Alan Nadon
