RCD TESTING BS7671:2018+A2:2022

Anybody notice the changes to 643.7.1 and 643.8 when it comes to RCD testing. In the note it says that "Regardless of the RCD type, effectiveness is deemed to have been verified where an RCD disconnects with in the time stated below with an alternating current test rated at residual operating current I△n"

So the minimum requirement is to set your instrument to RCD type AC and carry out the test even if you have a Type A or Type B RCD.

  • Good question Sparkingchip, I was wondering the same thing.

    I can't see anything in section 722 for additional testing requirements. The IET's CoP basically refers you back to BS7671 and manufacturers instructions for inspection and testing.
