13A UK socket tester with RCD test function

Handy socket tester, ideal for checking the supply to your caravan, EV, hot tub or any other appliance. Particularly useful for checking for the common issue of live-neutral reverse on European campsites. Also great to perform a basic check before plugging in an EV granny charger. 

Specification:

Detects missing E, L/E reverse, L/N reverse and missing N.  As with all plug in socket testers, the unit cannot detect N/E reverse.
Built in RCD tester - pressing the test button generates a 30mA fault, which should trip the RCD. Useful for establishing if a socket is RCD protected, or if an RCD is functioning correctly.
Easy to use with a clear LED indication of wiring status.
