This 110V 16A PAT Adaptor converts a 110V 16A socket to a 230V 13A plug which allows testing of 110V appliance such as power tools with any PAT tester. The adaptor is suitable for performing earth bond continuity tests and insulation resistance tests and the short 30cm cable helps minimise resistance. It should not be used for load/leakage tests or touch current measurement and should never be connected to a mains socket.
