The Socket Tester is an essential mains safety tester designed for testing socket wiring and RCDs. It will determine whether a socket is wired correctly or incorrectly. Used in conjunction with the coding table provided, the 5 combined indicators show the true status of the socket's wiring condition. It provides a true ground error indication through the LCD if dangerous contact voltage is present at the protective earth (PE). The use of 3 neon indicators for L-N-PE provides rapid detection of correct/incorrect socket wiring. It is equipped with an additional RCD tester for testing the operation of RCDs with a rating of not more than 30mA.
