RCD test 6 months

lyledunn

I was asked why the change to six months. To be honest, I couldn’t answer with confidence. I did hear that folk might be more inclined to test the RCD at  the twice yearly clock change. Can anyone point me to an authoritative explanation?

    Quite simply, it's a national requirement only (not in HD 60364-5-51 or IEC 60364-5-51), and it's what was decided upon when the original quarterly requirement was looked into in preparing BS 7671:2018.
