Abstract
Disclosed is an earth leakage detection device, which comprises a printed-circuit board incorporating an earth-leakage-detection control circuit, a reset function-equipped switch mounted on the side of one of opposite surfaces of the printed-circuit board, an earth-leakage-detecting current transformer mounted on the side of the other surface of the printed-circuit board, an externally connecting terminal for introducing and outputting an electrical power, and an electrical wire member arranged to penetrate through the earth-leakage-detecting current transformer and connected relative to the externally connecting terminal. In this earth leakage detection device, the reset function-equipped switch is connected to the earth-leakage-detection control circuit with the interposition of the externally connecting terminal therebetween. According to the present invention, components of the earth leakage detection device are arranged above and below the printed-circuit board in a compact manner using a significantly simple mechanisrh. Thus, the earth leakage detection device can be reduced in size and cost, and suitably arranged in a housing for various apparatuses, such as a copier and a printer.
