• Product Description

    The MARTINDALE CP501 Check Plug is a fast & easy way to ensure that 13A sockets are wired correctly, indicated by all three high brightness, long life neons illuminating. Wiring errors are indicated by one or more neons failing to light, with the pattern of lit neons indicating the type of fault. This failsafe socket tester system means that any neon not lit indicates a problem.

    The MARTINDALE CP501 has a virtually indestructible, flame retardant ABS case with a sculpted shape for easy removal. The CP501 Check Plug induces less than 5mA of earth leakage, well below RCD trip thresholds. As with all standard socket testers the Martindale CP501 only verifies the presence of an earth, it does not assess its quality. Similarly neither it nor any other tester can detect earth neutral reversal.
