Looked at it today...I was wrong, it is a fused switch, 1200 Amp GFI, the kind you have to pump the handle twice to turn on.(high pressure contact switch) The rep I called is looking at the job file to see if it has been programmed (or calibrated?) properly. They will have a record of it if it was. I was not involved if it was, but will report back what I find out. Must be related to this feature, as the load is nowhere near 1200 Amps and there is very little motor load. It has no transformers on the load side of it, just the one for 4160 to 208 which feeds it.
