Martindale PC104 63A 3-Phase Socket Tester

The three-phase Martindale PC104 socket tester checks for phase, phase sequence, and PE in addition to promptly assessing the wiring quality of four-pin 63A sockets. To start the socket tester's examination, just insert the PC104 into the preferred outlet. The presence of phases, as well as any faults or missing phases, will then be shown by the illumination of green and red LEDs.
