Martindale CP501 Classic Check Plug
The CP501 Check Plug’s a fast and easy way to ensure that 13A sockets wired correctly, indicated by all three high brightness, long life LEDs illuminating.
Wiring errors indicate by one or more LEDs 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 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 CP501 only verifies the presence of earth, it does not assess its quality. Similarly neither it nor any other tester can detect earth neutral reversal.
