I am hooking up a temporary service on a commercial site. I found an already built temporary service at our shop. It consist of a meter with 4/0 AL coming off the line and load side. The load side goes into a gutter and is then tapped with 2 sets of #2 Cu. Each set goes to a 100 amp single phase panel. According to table 310-16 4/0 Al is only good for 180 amps. Wouldn't I need 250kcmil? Or is there something I am missing. Could I change the main breaker in the panels to 80 amp?
