Hi, My downstairs ring main kept triping the 32A MCB.
I think I have found the fault, a cable from one socket to another was under a concrete floor and I noticed a low resistance between the live and earth.
I have disconnected the cable and all now seems fine.
I suspect the cable has been crushed under the floor?
I did also notice there is a PD of 182VAC between the earth and live, is this correct?
The PD between the live and neutral is also 182VAC, is this a little low??
Thanks for any help.
