Receptacle Tester

A receptacle tester or outlet tester is a device used to verify that an AC wall outlet is wired properly. The tester itself is small device containing a power plug and several indicator lights. Although a multimeter could be used to perform a series of tests which would give the same results, an outlet tester can perform the entire array of tests by simply plugging the device into the outlet once and observing the state of the lights. The tester performs several tests at once but the tests themselves essentially fall into two categories: tests which determine that the outlet has power connected, and tests which determine that the outlet is properly wired for safe operation.

Famous quotes containing the word receptacle:

    A lonely man is a lonesome thing, a stone, a bone, a stick, a receptacle for Gilbey’s gin, a stooped figure sitting at the edge of a hotel bed, heaving copious sighs like the autumn wind.
    John Cheever (1912–1982)
