1. An appliance leakage current interrupter (ALCI) for interrupting the flow of current through a pair of lines extending between a source of power and a load, said appliance leakage current interrupter comprising:

  • a. a circuit breaker having a pair of normally closed switches, one switch being located in each of said lines between the source of power and the load;

    b. a relay circuit for selectively opening the pair of normally closed switches;

    c. a fault detection circuit for detecting the presence of a ground fault condition in said pair of lines and for causing said relay circuit to open said circuit breaker when said fault condition detected exceeds a predetermined value, said fault detection circuit comprising an integrated circuit chip and a transformer; and

    d. a single-sided circuit board, said single-sided circuit board having a bottom surface and a top surface, the top surface having a pattern of conductive paths;

    e. wherein said integrated circuit chip is mounted on the top surface of said single-sided circuit board and wherein said relay circuit and said transformer are mounted on the bottom surface of said single-sided circuit board.
