Martindale CP501 Check Plug is a fast & easy way to ensure that 13A sockets are wired correctly

Martindale CP501 Check Plug

With over 2 million of these Martindale CP501 Check Plug sold, the Martindale CP501 Check Plug is the most popular socket tester available. The Martindale CP501 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.

  • Quick & easy testing of socket wiring with the UK’s favourite check plug
  • Detects 28 fault conditions
  • Three bright LEDs with clear & simple fault codes on the plug
  • Tough sculpted design for easy removal

Martindale CP501 Check Plug comes complete with a calibration Certificate Traceable to National Standards when purchased new.
