I understand that when carrying out RCD testing an RCD should trip within 300ms at 1x and 40ms at 5x but is it common that on occasions for the RCD to trip quicker at 1x than 5x. I never had it occur personally.
I am just looking at some old certs and on some circuits the RCD is tripping marginally quicker at 1x than 5x.
Any thoughts?
