Socket & See SOK 36 Professional Socket/Earth Loop/Polarity/RCD Tester Details

The SOK 36 is used to check that the internal wiring of sockets is all correct, and when used it can be used to check true earth loop, polarity and to test residual current devices (RCDs).

With the ability to detect over 17 wiring configurations, including 'good' and 'bad', the SOK 36 also is one of the first socket testers in the world to tell you exactly where the fault lies, whether its in the Live, Earth or Neutral.

Key Features

  • Audible different tones give clear indication of the status of wiring
  • Bright LEDS build in for wiring detections
  • Unique circuitry ensures the socket tester will not trip RCDs
  • Continuous audio tone for good, warbling tone for bad configurations
  • Works with accuracy even on noisy circuits
  • New patented 'Fault Locate' allows you to find up to 17 fault wiring conditions
  • Built-in self check
  • Tests true earth impednance
  • LEDs also indicate status of earth loop and it performs full earth loop test

Not fit for purpose

Review by BookIT (Posted on 16/10/2018)


Had a SOK 32 for years, great bit of kit. Needed another tester bought one of these. First problem is sound is so high pitch anyone my age struggles to hear it! ELI test is hopelessly inaccurate. Manual says Good is less then 1.8 ohm, my unit showed errors for sockets which my Fluke 1664 measured at 1.1 ohm . Returned for refund.

Useful quick assessment of circuit

Whilst the professional tester cant be used for certification, it is a useful quick first guide to the circuit condition.
