Abstract
An electrical continuity tester has a handheld housing having batteries, switch, test bulb, a probe and a power cord having a grounded plug on the end of the power cord. The handheld tester is used to first check that a common grounded outlet is wired properly by closing the switch and observing the test bulb. The test bulb should come on if the grounded outlet is wired properly. After the outlet has been verified, the probe can be used to touch any metal or conductive parts of any electrical device or appliance to verify that the metal part is properly grounded or wired to the hot side of the circuit. The tester's the cord and plug provides one connection and the probe provides the other connection.
