I have been asked a question in which i am unable to find a clear answer. So I will ask it here.
So if i am feeding a 3 phase 480V switchgear from a pole mounted transformer with parallel conductors is it allowable to land the sets of parallel feeders on seperate breakers? These breakers at one time fed the buss from generators but they are now out of service. i am looking to use these breakers to feed the buss from grid power. The only advantage i can see to doing this would be for future breaker maintence by shedding all the load except critical items and being able to work on one breaker without shutting completely down.
