I had a transformer 45 kva 480 volts pri..120/208 sec.
The elevator guys use a FMC on the secondary side like me on the primary side of the transformer ,The transformer is protected for a 70amps fuse only on the primary side. I sized my EBJ (primary side of the transformer) based on table 250.122 , for the breaker size. On the secondary how i have to size the EBJ ? It will be the same size as the primary?
