Was wondering how to calculate how much amperage will be on a grounded conducter. I understand in theory it's purpose on a mutli-wire branch circuit, but how is it different in 3-phase? I was working on a 225 amp main lug only panel today and the phases were somewhat balanced and it made me think.
Black leg had 42 amps.
Red leg had 53 amps.
and Blue leg had 41 amps.
But the nuetral had 25 amps. Does this seem right to you?
