Abstract
At least one aspect is directed to a transfer switch including a first input to couple a first multiphase low voltage electrical supply to the transfer switch, and a second input to couple a second multiphase low voltage electrical supply to the transfer switch. The transfer switch also includes a first set of switches in electrical communication with the first input and a second set of switches in electrical communication with the second input. A control module monitors and controls operation of both the first set of switches and the second set of switches to detect a malfunction of any switches included in at least one of the first set of switches and the second set of switches and prevent the first input from being placed in electrical communication with the second input.
