Live earth fault on every leg of the ring

[T Wilson Elec]

Brief run down for you all

Checked end to end of ring that’s sound
Meggered LN sound NE sound LE 0.03

Split the ring same stuff
Split it again same stuff again

Long story short stripped all sockets off on the ring and every single leg has a LE fault

Was rewired 2010

Only logical thing I can think is just a bad drum of cable was used ?
The CU is a screwfix off brand thing so one can only assume it is screwfix special T&E used

Anyone got a better suggestion please let me know left me scratching my noodle for a while

EDIT:
there are no neons
The cable is twin and earth 2.5mm
All sockets were removed ring completely split at every outlet

what value is the reading L-E?

0.03 mate when ring was connected the it varied from leg to leg got as high as 3.48

Is this twin and earth cable

Yes mate standard stuff 2.5mm

if those readings are in Megohms, the 3.48M is acceptable. the 0.03 looks like a neon. hidden FCUs?

Any of the following still connected?
neon lights on spurs or switches
surge protected sockets or usb sockets
rcd sockets
rcbo on supply?

That is sounding very much like bad cable. Odd it is just the L but presumably it could have been the brown PVC mix that was contaminated in some way.

I wonder if it was like that new and the installer just ignored it, or if it has gone bad with time?

The rented "anti vandal site office" we have just is a bit like that, but all circuits in the 0.2M region for both L-E and N-E even though not much T&E. Not ours to fix though

But a neon to E?

 

[pc1966]

If you have isolated a section socket-socket and it shows the same behaviour surly it has to be the cable?

They are yes mate 3.48M is acceptable but not on a 12 year old install NE LN>999M

House is fairly simple no fcu just two living rooms on one ring

Surge protected extension leads still plugged into each separated section?!

Every thing is disconnected pal literally just legs out the wall and every single leg has a LE fault some 0.03M next one coul be 0.59M one leg was 3.38M but every single leg was faulting

Can you get enough of the T&E to read the manufacturer's details, etc? Wonder if there is any site with recall information on bad cable.

Not at the minute left my suggestion and findings with homeowner he’s ringing home insurance to see if he can get them to foot the bill
