I once visited a large Navy hospital that had several large backup generators.? They got them all up and running connected in parallel and then connected to the commercial power coming into the facility.? Raised the voltage and took over the load and then cut the commercial power away to let the generators carry the load for a test time.? Did the opposite to go back on commercial power.?
