You can switch off locally but you can't always be certain that every load is isolated, that's why the recommended procedure is on the outgoing terminals of the device with loads disconnected.

The capacitors etc. don't actually make the RCD/RCBO trip any later but as wirepuller says, they 'trick' the rcd tester into displaying a higher trip time.



so basically disconnect these items out of the loop for the benefit of thetest.

however only if your not achieving your times!

i ask this as ive never had this problem testing!
 
I think what baffled me was I had two other socket circuits on that RCD side and they were fine, so why would 1 out of 3 provide a high trip time anyone!?
 
the rcd needs testing once at source. you are proving it works when inbalanced. if it works at source it will work on every circuit connected to it. 0x 1x 5x and push the button. all done at the board or at any one circuit
