testing A type RCDs

wallywombat

This new youtube video https://www.youtube.com/watch?v=CqQfN3-nf4s from efixx features reps from Lewden, Megger and ECA having a half hour discussion on how type A etc RCDs should be tested, in particular relation to devices being returned to the manufacturer in error as being faulty.

The rough consensus seemed to be: to satisfy BS 7671, test on the AC setting of your tester, checking for either ≤40ms @ ≥ x 5 for additional protection, ≤300ms @ x 1 for fault protection.

You can in addition test on the A setting of your tester, but now you're not in BS 7671 territory and the times you get may not satisfy 40ms - but the device may still be within the requirements for BS 61009 etc.

Discuss….

    It’s interesting and you can see how confusion arises and which result should be recorded? How to make something that was easy complicated. So do you just carry out the AC test, type A or both obviously the Megger man is both and Lewden just the AC.
