Earth - neutral fault on ring final, any ideas on how to find with ease.

[ericmark]

I have split the neutrals and have half of the ring final back, I split on a USB socket, as thought the socket may have been faulty, and not have power back to 85% of sockets, that will do for tonight, now I need to find the fault, the RCBO type AC did not switch the neutral, so swapped for a type A which does switch the neutral so I can now easy switch off to continue fault-finding.

But many sockets had to get to, so considering any tests to reduce the amount of furniture I need to move. To access a socket I can cut a hole in the back of cupboards, but to remove the socket really need more room, so trying to think of a way to test without removing display cabinet.

Disconnect at a socket either side of the cabinet and test.

Its bound to be a problem at the socket you cant get to.

Did you do any IR tests?

 

[ericmark]

Did not need IR test, was down with multi-meter test. When I got one section working, was surprised how much I had not unplugged. The socket which is still not powered is not where I expected to find it, I have been trying to work out likely run, but since earth neutral the fault may have been there for years, some sockets behind this and I am not looking forward to removing the left two units and going behind them, specially since not sure if that is where the fault is.
