Loop testing is a quick, convenient, and highly specific method of evaluating an electrical circuit for its ability to engage protective devices (circuit breakers, fuses, RCD’s). A “loop” is defined by including unsuspected elements, where current has found parallel paths to ground. Because a ground loop determines the effectiveness of protective devices, it is crucial to be able to measure it, in order to detect and correct problems.
