Loop testers are used to test the safety of electrical systems. These devices measure the impedance of the short-circuit loop between the outer conductors of a circuit, calculating the Prospective Short-circuit Current (PSC). The protection of the circuit (circuit breaker) must therefore trigger at a lower current than the prospective short-circuit current to avoid excessive heating of the lines and thus a fire hazard.
