Hello All! Long question so please bear with me...
NEC 2008 Section 695.1(B)(2) states that pressure maintenance (jockey) pumps are NOT covered by the NEC...
That being said, section 230.2(A) states 2 services can supply the same building, such as a seperate service for fire pumps.
Service #1 supplies ONLY the fire pump.
Service #2 supplies normal power for building AND jockey pump, WITH generator backup.
This arrangement makes no sense to me, but regardless, I can not find anything in the NEC that would make this set up a violation.
Is this setup common??
