Earth Potential’s 13amp UK socket tester is designed to be simple to use and understand. Just plug the tester into the socket, turn the socket on and the results are displayed immediately. It is safe to use as there is no need to unscrew the socket from the wall to check the connections. The tester will indicate the presence of live, neutral and ground connections as well as polarity reversals and missing connections. For a correctly wired socket the indications should read (left to right) Unlit, Green, Green. If the tester shows any other result we strongly advice that you contact a qualified electrician to investigate and correct the fault. An RCD, or earth leakage circuit breaker test facility is also included. Simply press and hold the button on the front of the tester for a couple of seconds. If the RCD breaker is working correctly the indicators on the tester should all go out indicating the loss of power to the socket. Power may also have been lost at other sockets in the area. Don’t forget to turn the breaker back on again at the buildings distribution board after the test in order to restore power to the tested circuit! The AST01UK is designed to fit a standard UK 13amp socket and operates on 220 to 250 volt power.
