Ground fault circuit interrupter, circuit, circuit tester and method

A circuit tester comprising a ground fault circuit interrupter having opposite line sides, opposite load sides and a ground terminal, said tester having a first pair of electrical leads having oppoiste ends, said tester having a second pair of leads having oppoiste ends, said tester having a ground lead having opposite ends, said leads of said first pair being connected to opposite load sides of said interrupter in series at one lead end, said leads of said second pair being connected to opposite line sides of said interrupter in series at one lead end, said ground lead being connected to said ground terminal of said interrupter at one lead end, said other of said lead ends of the first pair, second pair and ground lead being distal ends, said ground fault interrupter is mounted on a side wall of a box having first, second, and third openings, said ground fault interrupter being within said box, said first pair of leads extending through said first opening, said second pair of leads extending through said second opening, said ground lead extending through said third opening, said distal ends being outside of said box, said distal ends have removable connectors secured thereto.

A method of testing an electrical circuit having a circuit overload device, several electrical outlets and at least one appliance connected in parallel outlets and at least one appliance connected in parallel comprising:

• defining said electrical outlet, appliance and said overload device of said circuit, determining the first electrical outlet of said circuit, and substituting a ground fault circuit interrupter for said first electrical outlet in parallel with said remaining electrical outlets and said overload device of said circuit to indicate current leakage in said circuit distal from said ground fault interrupter in amounts greater than about 0.005 amperes.

An electrical circuit comprising a power source, a circuit overload device, a plurality of ground fault circuit interrupters and one or more electrical outlets connected in parallel, one ground fault circuit interrupter connected between said overload device and a first of said outlets, said overload device connected between said power source and said one ground fault circuit interrupter, and another ground fault circuit interrupter connected between said first of said outlets and another of said outlets.
