I am looking at a new service installation with 480 utility service to an MDP. The MDP is serving Multiple Step Down Transformers which are feeding a panel with a main breaker. The code commentary says the GEC connection can be at any point between the source terminals and the first disconnecting means.
If the GEC is at the transformer then the neutral bar in the panel should be isolated. If the GEC is at the transformer then the Neutral bar in the panel would need to be bonded.
The electrician put a ground rod at the transformer AND at the panel.
Is this ok? and if it is should the Neutral bar in the panel be bonded??
