Went to a property yesterday to do some odds and sods, replace the cu and do some remedials following a condition report customer obtained prior to purchasing the property. The cu is made by GE and was installed in 1997, half the board rcd protected and half not.
One of the observations on the report was a C3 for 'rcd will not reset after test'. After brushing against the test button and tripping the rcd I was unable to reset it. I then tried to reset it with all rcd protected mcbs turned off and then removing one by one all the neutrals from the rcd protected neutral bar, still no joy.
How did the person who performed the periodic a couple of months ago manage to undertake the trip tests and then re-energise the installation when he had already diagnosed that it would not reset? Am I missing something?
I did manage to sort the C2 for cooker hood protected by a 13A fuse all on my own!!
