Martindale CP501 Check Plug

Martindale CP501 Check Plug

The CP501 Check Plug is a fast and easy to use Socket Tester that ensures that 13A UK sockets are wired correctly as, indicated by all three high brightness, long life neon's illuminating. Potential faults are indicated by one or more neon's failing to light. This failsafe system means that any neon not lit indicates a problem! A great Socket tester.

The Martindale CP501 check plug is fitted with a 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 socket testers the CP501 only verifies the presence of an earth, it does not assess its quality. See the NEW Martindale E-Ze Check Xtra™ earth loop impedance socket tester below for verification of earth loop impedance.
