Sınama Cihazı

An electrical testing device for determining the continuity between ground terminals of an electrical power cord and determining the electrical grounding of an electrical power tool. The electrical testing device can also be configured to determine the proper polarity on each of the hot, negative, and ground cord wires of an electrical power extension cord. The electrical testing device includes a plastic case housing one or more batteries which supply power to a test button and the ground terminal of a female receptacle installed in the case. The top surface of the case includes a female receptacle, a test button, and a ground light. The top surface may also include a male plug and an additional female receptacle installed in the case. On the side of the case is an extending metal contact element. The test button is a single pole momentary contact test button. When this test button is actuated it closes the test button contacts thus completing a circuit which will illuminate the light if the light and the battery are good. #
