Could I just ask for some advice , as I am doubting myself..., or my test results
Dual RCD board, in an unoccupied house, (between moves)
Recent rewire, probably a year old - No installation certificates.
Doing insulation resistance tests.
Global test, gives poor readings, so I separate all the lives , neutrals,
and test to cpc - still the same so I separate cpcs , and still the same.
One side of the RCD, these circuits test around the 200 M ohms. For a new install I would expect off the range. (Megger 1741, so 999)
The other side, Im getting 0.2 Mohms on every circuit.
This is with all the circuits separated.
Testing between line and CPC's and Line, with another circuits CPC, I still get a really low reading in the 0.2 Mohms range.
Neutrals- CPC readings in the 200 Mohms range.
Circuits are Oven. two socket circuits and two lighting circuits.
Lighting circuits have dimmers, transformers etc. nothing plugged in, well its an empty house.
Am I missing something that can effect a Line to CPC IR reading.
Thanks
