Martindale CP501 Classic Check Plug
With over 2 million of these socket testers sold, the Martindale CP501 is the most popular socket tester available. The classic check plug is a quick and easy way to ensure that 13A 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.
The plug induces less than 5mA of earth leakage, well below RCD trip thresholds.
Detects 28 fault conditions.
