I was thinking about DB changes earlier and started to stumble when it came to IR Testing...

    Testing RCBO x5 times

    Hello everyone, Is it necessary to test RCBO x5? Some say that you can’t even test at x5 times because it can damage RCBO. Others that you can, but we don’t put the result in testing sheets. I found a recommendation that it is advisable to test x5. Cheers
