Abstract: An electrical device for automatically combining two input power source supply circuits with either aligned or unaligned phases, into a single operational circuit, with an output load capacity totaling approximately the sum of the two lower capacity power supply circuits. The device and adapters, through a series of coupled relays and contactors, incorporates internal circuitry and components which sense the phase relationship and alignment of the supply circuits, and depending upon conditions chooses the correct path, and automatically connects the supply circuits to the load circuit without the need of manual switches, or additional adapters.
