I'm sure this has been asked before but I can't find it or an NEC reference.
Secondary conductors (from a 480V-240/120V 50KVA xfmr) single phase 3 wire sep. derived system go to 3 pole fusible disconnect. 2 poles fused (150A), the third pole of the switch is used for the neutral (grounded) conductor, and a busbar installed in the fuseholder (instead of a fuse).
Is there anything wrong with this (NEC)?
Thanks
