How to Test an RCD - BS 7671 Amendment 2 EAL Awards City and Guilds Changes to BS 7671 under Amendment 2 of the 18th Edition of the Wiring Regulation requires RCD’s to only be tested on the AC setting regardless of the Type of RCD and at the rated residual operating current of the device. This simplifies the testing process so even if you have an A, F or B Type RCD you only need to test it on the AC setting of you MFT tester and at 1 x delta n (often this is 30 mA) with a maximum disconnection t

3 Lead RCD Test in the Consumer Unit on RCBO's Saving Time During the Live Testing's Process Student training aid for testing an RCBO rated at 30mA using a MFT Megger tester. Includes a full demonstration of how to test the RCBO using 3 leads from with the consumers unit. 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 Impe
