Classic Check Plug (MARCP) Classic Check Plug (MARCP)

The MARCP Check Plug is a fast and easy way to ensure that 13A sockets are wired correctly, indicated by all three high brightness, long life neons illuminating.

Wiring errors are indicated by one or more neons failing to light, with the pattern of lit neons indicating the type of fault. This failsafe system means that any neon not lit indicates a problem.

The MARCP Check Plug has a virtually indestructible, flame retardant ABS case with a sculpted shape for easy removal. The Check Plug induces less than 5mA of earth leakage, well below RCD trip thresholds.

As with all socket testers the MARCP only verifies the presence of an earth, it does not assess its quality.
