Professional Earth Loop Impedance / Polarity / RCD Socket Tester

A SOK36AU Professional Socket, Earth Loop, Polarity & RCD Tester is an ideal accessory for any Portable Appliance Tester. It is designed to identify a variety of faults with socket wiring, but most commonly used to reveal sockets with poor earth. Simply use your PAT Tester to test one socket of an extension lead and use the SOK 36 Professional Socket, Earth Loop, Polarity & RCD Tester to test the rest! A Socket Tester really speeds up PAT Testing.
