3 Phase Exposed Earth Leakage Adaptor - 5 Pin 20 Amp

This exposed earth adaptor provides an easy and safer way to test 3-phase appliances for current leakage than traditional methods. The exposed earth conductor allows testing of either differential leakage or earth conductor current. Measurements can be made using a current leakage clamp meter or current leakage clamp accessory for testers such as the Metrel 3309BT.

The adaptor features a unique earth test lead connection, including a 4mm banana plug adaptor. This allows for testing of earth continuity without needing to disconnect the adaptor prior to the leakage test. The piggyback-style 4mm plug enables both the connection of the earth test lead and the current leakage clamp to the Metrel 3309 terminals simultaneously.
