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.

    Hmm interesting. I had not spotted that one. I had noted the demise of the 5 x test and a lack of any ramp test I hoped would creep in
