The 415V 32A 4-Pin Appliance Adaptor is a 30cm adaptor with that has minimal resistance. It can perform earth bond continuity tests and insulation resistance testing on 415V 32A appliances with 4-pin plugs which are frequently found in three-phase systems. It converts a 415V 32A 4-Pin socket to a 230V 13A plug and is compatible with any PAT tester. It is not suited for load/leakage testing and touch current testing and should not be plugged into the mains.
