MARTINDALE CP501 13A 240V CHECK PLUG

The classic check plug is a quick and easy way to ensure that sockets are correctly wired, indicated by 3 bright long life LEDs. Wiring faults are indicated by one or more of the LEDs failing to illuminate, with the pattern of lit LEDs indicating the type of fault detected. This fail-safe system means that any LED not lit indicates a fault. The robust ABS housing has a sculpted shape for easy removal and there is a look up chart on the tester for quick fault diagnosis.
