The short answer is "no", somewhere in 695 it tells you to isolate the fire pump disconnecting means from all other disconnecting means and label it so there's no confusion. And if you're using a breaker instead of an unfused disconnect, it's rated for the locked rotor current, right? Modern fire pump controllers usually have the properly sized OCPD inside the controller cabinet.
Gadfly/RB1,
Thanks for all the comments.
Gadfy- I believe that you are referring to section 695-4 3 (a) normal power source.
I agree with RB1 comment "For high-rises, the International Building Code classifies fire pumps, elevators, and ventilation systems as standby loads". This should be verified with AHJ and local fire marshall.
According to 695-4 3b. Disconnecting means for an on site standby generator used as an alternate power source shall be installled in accordance with 700.10(B)(5) for emergency circuits, indicating for wiring of two or more emergency circuits supplied from the same shall be permitted in the same cabinet.
Fire pump feeders can not be installed in the same vertical switchboard section with conductors supplying loads that are designated or classed as legally required standby. To help minimize inavert opening of the fire pump circuit, the disconnecting means is required to be capable of being locked in the the closed position.
Can't see where in the code it indicates for the fire pump alternate source generator breaker must be isolated from other emergency circuits. Appreciate if you can direct me to this section of the code.
Breaker sizing for a generator breaker as altenate source should per NEC 430, Max 250% and is not required to carry the lock rotor current indefinently.
Appreciate more comments on this subject.
