About this item
  • 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
  • As with all standard socket testers the CP501 only verifies the presence of an earth, it does not assess its quality. Similarly neither it nor any other tester can detect earth neutral reversal

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
