Abstract: A system and method for controlling power includes a power source, a plurality of primary control circuits (20a - 20n), a load, at least one secondary control circuit (22a - 22n), a switch circuit (24), and a control channel. The plurality of primary control circuits (20a - 20n) are connected to control load power from the power source to respective ones of a plurality of load power inputs. The load is configured to receive power from the plurality of load power inputs. The at least one secondary control circuit (22a - 22n) is connected to the power source, and the switch circuit (24) is connected between the at least one secondary control circuit (22a - 22n) and the plurality of load power inputs. The control channel is configured to control the switch circuit (24) to connect the at least one secondary control circuit (22a - 22n) to a selected one of the plurality of load power inputs.
