I'm trying to put in a 200 amp subpanel in my shop. I have a commercial eaton 400amp panel. It takes type BA and BAB breakers. I can't find either of these on more then 100 amps. I did buy a 100 amp breaker to work for now however I already ran 2/0 copper to the subpanel so I would need to cut down the conductor to fit in the 100 amp breaker. I know it's not advised to cut down a conductor but i cant seem to come up with an alternative. I tried calling a couple of electricians and they either don't have the time or don't do commercial work. Any advice would be appreciated. I can't imagine for a commercial panel the largest breaker available is 100 amps there are other breaker types listed on the panel but I can't find any other those.
