Claim 0:
1. A series arc detection apparatus comprising:
a power source terminal;
a circuit load terminal;
a protective device having a Line In side, a Line Out side, and a trip signal input, wherein the Line In side is connected to the power source terminal and the protective device is configured to interrupt an electrical connection between the Line In and Line Out sides when a trip signal is received at the trip signal input;
a wire conductor having a first end and a second end, wherein the first end is connected to the Line Out side of the protective device and the second end is connected to the circuit load terminal; and
a differential voltage sensor connected on a first end via a sense wire to the circuit load terminal and connected on a second end to the Line Out side of the protective device, the differential voltage sensor additionally connected via a trip wire to the trip signal input of the protective circuit.
