The 400 Amp ASCO 185SE 2-wire Start Service Entrance Rated NEMA1 are 2-wire control switches that are compatible with all 2-wire start systems from all manufacturers. The switch monitors incoming utility power. When the utility power fails it starts the generator and transfer the emergency load onto the generator. After the utility power is restored it will transfer the load back to the utility source, cool down the generator and then return to a standby mode.
