The 110V 32A Extension Lead Adaptor is a useful adaptor that is universally compatible with any PAT tester. When used in conjunction with a 110V appliance adaptor, it can be used to test 110V 32A extension leads that are typically used in the construction sector. It will carry out an earth bond test and an insulation test although it is not suitable for load/leakage testing or touch current testing. It must not be plugged into a mains socket.
