The voltage to ground on the system is 110/208/110 3 wire. Im not sure if this is a corner grounded system or a y there are no labels. phase to phase its 213/213v/244v. interesting thing There are 2 small 100 amp, year 1925 transformers connected to the 110 legs(1 for each leg). only thing I can make out is 100 amp ratio 20 on the label? I have no idea why they would put those on there? They are mounted in a 6x8 pull box and go up to the meter in #10awg wire 1 hot line per phase line side and 2 coming down to the transformer from the load on meter. The system is 2/0 i believe its in rag wire hard to make out. They have them on 200amp breakers witch i think someone changed the amps. i proposed ripping it all out and puting a new meter/panel in. My concern is that those transformers burned up they bypasssed them then had this heat up problem. I have no idea why those transformers where in line my only theory is the old meters where not made for big gage wire so they installed the transformers to connect meter??? Also what the proper way to ground this 3 wire no nuetral system (2 ground rods continuos cold water bond?
