The 3-phase adaptor lead features a 32A male plug and a 32A female socket, enabling the current leakage testing of 4-pin appliances using many commonly available 3-phase 5-pin leakage adaptors and 5-pin appliance testers. It allows 5-pin current leakage adaptors or instruments to connect to a 4-pin power source for testing 4-pin, 3-phase appliances.
Important Note: This adaptor does not allow 5-pin appliances to be operated or tested from a 4-pin power source. It is not designed for in-service use and is not suited for RCD testing of 4-pin power source RCDs using a 5-pin, single-phase RCD test adaptor.
