Overview: A 3 phase adaptor lead featuring a 20A male plug and a 20A female socket allowing 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 be connected to a 4 pin power source for testing 4 pin 3 phase appliances.
This adaptor does not allow 5-pin appliances to be operated or tested from a 4-pin power source and is not designed for in-service use. it is also not suited to providing a means of RCD testing 4 pin power source RCD's using a 5-pin-single phase RCD test adaptor.
