We have a 12.5kv transformer from the utlity company that we are knocking down to 480v and feeding an MCC. I was told today by an electrical engineer that the arc blast would be much higher on the 480v side than on the 12.5kv side even if both sides theoretically had 200 amps each. Can anyone explain why that would be in laymans terms because when he was explaining it to me he really confused me? Sorry if this is a dumb question, I haven't got alot of experience on the industrial side.
