The 415V 16A 5-Pin Appliance Adaptor allows a regular PAT tester to be used on 415V 16A appliances with 5-Pin plugs that are used in three-phase systems. The adaptor converts a 415V 16A 5-Pin socket to a 230V 13A plug and is compatible with any PAT tester. The short length of the adaptor minimises resistance during earth bond continuity tests and it can also be used to test insulation resistance. It is unsuited to load/leakage testing and touch current testing and should never be plugged into the mains.
