    But still a problem if you needed a 125 amp feeder. With (B)(7) and 125 amp - you are about 4 amps too much for #1 so 1/0 Aluminum is what would be required.
    Your contractor needs to replace that SER, are you sure he had a license???

      Since this is becoming a DIYer thread I am closing it.

      Cubgirl, good luck with getting this resolved.
