Hypothetical situation?
Overcurrent protection for the primary conductors is about 125 feet away from a 75 KVA transformer that is to be mounted ten feet AFF. There is no drop ceiling.
The secondary conductors are about ninety feet in length and feed a 225 Amp panel.
It is my assumption that, in this installation, the secondary conductors would need overcurrent protection because they are over ten feet 240.21(C)(6) 240.92(B)(1)(1).
Does the transformer need overcurrent protection additional to the circuit breaker feeding the transformer primary conductors or would a disconnecting means be code compliant?
