Renovated house low r2 readings !

[Soulsurfer]

Just been sorting out a right mess during a house renovation and tests on newly installed ring final are r1 0.35
rn 0.35 & r2 was expecting around 0.58 but had consistently 0.00 Ohms.
MFT was zeroed again from scratch and was still giving a zero resistance reading
Almost all cable is new and IR tests all perfect. Any ideas ? Thanks

Maybe you could add this to the never have i ever thred , we have all done some silly things in the past , at least what you have done is not dangerous and you found what was coursing your low reading before you stripped the installation down back to its component parts .

Was just getting to that Flanders was taking all the sockets off ! Oh dear, any better ways to extend cables to new boards without din rail would be a go ! Ha ha, just wanted a secure connection rather than box of wagos or crimps! As customer didn't want to go full rewire, would've been far easier and more cost effective.

Parallel paths

Oh there were parallel paths alright ha ha in the end about eight circuits of paths

Extended most of the circuits from old 3036 board to new board and used a box with din top hat mounted creating a huge earth bus bar in effect felt a right prat

10 out of 10 for updating us.... But your description suggested said ring with the problem was all new except one leg.....

Yes it is all new right to old board position in garage around a metre from new board, had to extend with new cables. Sorry fella.

Just don't use the specific 'earth' terminals for your CPCs:
