EICR - RCD Wont trip on test button

Redo the IR but leave the cpcs connected. As already mentioned never disconnect cpcs to carry out an IR test.

I done it connected 1st then removed them to test just that circuit

Just a thought but are your spare RCD's Brand New?

The above was posted 3 years ago and they had the same problem turns out all 3 RCDs were faulty

They were second hand parts from a specialised supplier because new parts were not available but you may have the same issue?

Argh....!
We need IR figures, not 'it tests ok'.
Now we're all thinking 'I bet there was a N-E fault.
