3 Lead RCD Test in the Consumers Unit on RCBOs Saving Time During Live Testings Process

Note my default position is always 3 lead testing as it’s my preferred method of testing for Earth Fault Loop impedance when RCD protection is present. 2 lead tests can also be carried out for both testing RCDs and circuit Impedance.

Student trading aid for testing for external earth fault loop impedance Ze test using a MFT Megger tester. Please note this test is carried out with only the external earth path in circuit. Includes a full demonstration of the test in a domestic single phase installation in the real world.

Student training aid for the live test measuring prospective fault current PFC using a MFT Megger tester. Includes a full demonstration of how to measure PFC current. This test is shown being done out in the real world.
