A controller is disclosed for determining that the currents from the two AC power sources are correctly phased. Required circuitry can be disposed within a housing from which extend power cables having single phase 240V AC, 50A male connector plugs connected at remote ends. Prongs in each of plugs can be arranged so that the plugs are connectable to a 240V, single phase AC source. A power cable, having a connector at a remote end, can also extend from the housing. The power cable connector can be connected to an AC power supply. The power cable connector supply a power transformer with single phase AC power at 240V and 100A. The circuitry can assure that the phases and voltages of the two AC sources driving the connectors are properly connected to the connectors to enable the cable to supply the power cable connector with single phase AC.
