Martindale Check-It Socket Tester

The CP501 Check Plug is a fast and easy way to ensure that 13A sockets are wired correctly, indicated by all three high brightness, long life LEDs illuminating. Wiring errors are indicated 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. The CP501 Check Plug shows 28 potential faults.
