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.

Videos are training aids for City and Guilds (C and G) and EAL courses Level 1, 2 and 3.
