RCD TESTING BS7671:2018+A2:2022

sparkiemike

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.

    Hi, I thought the test button HAD to be operated afterwards on an EICR, as you are testing it as you initially found it, not after ‘repairs’. I.e resetting a sticky RCD. Just a note too, that OZEV wanted proof of my Metrel tester 18th edition, by photo, before they would enrol me. Thanks

    I have often wondered similar myself - what is the point of assuming someone will push a test button when we know they never do ... and to put a label on something hidden away in a cupboard won't help remind anyone to do it either.

    Well, which is the lesser of two evils: a label in a cupboard which will never be read, or a certificate in a drawer which will never be read?

    Or perhaps, which is more or less likely

    I don't think there's an answer to this. There are lots of warnings dotted around appliance instruction manuals - but we never read those either. Often get thrown in the bin, which leads to the argument twice a year about how to set the clock on the cooker.

    Know exactly what you mean Graham. I could have cheerfully chucked the oven out the back door! Instructions? Well we have the ones for several dishwashers, fridge freezer and a ride on lawn mower but the instructions for the oven, well God only knows! So its an hour behind at the moment and I cant figure out how to alter that. Never mind...nine year old nephew is coming for Easter, I am sure he will sort it in a jiffy!
