The PeakTech 2715 is a loop tester and circuit tester designed for checking the safety of electrical installations. This device measures the impedance of the short-circuit loop between the live conductors of a circuit, calculating the expected short-circuit current. Therefore, the circuit protection (circuit breaker) must trip at a lower current than the expected short-circuit current to prevent excessive heating of the wires and thus avoid fire hazards. The PeakTech 2715 is nearly indispensable for carrying out new installations due to its functionality and robust design. It is also the ideal companion for general inspections of electrical systems.
