My question is about backfeeding a transformer. This is a 480 delta grounded system. The transformer will be a 480 delta too a 480/277 Y 4 wire. I havent ran across this situation yet. I just don't understand how this can backfeed without blowing anything up! please help me understand.The engineer said it will be fine but wont explain. Talked to another engineer and he said he wouldn't be caught even near it. Seeing that I am the one turning it on I just want to be sure. Any input or insight would be helpful.
Thanks
