Now i am pulling my hair out

[buzzlightyear]

I am now checking for any parrell paths so here it goes up stairs ring cpc r1. In board in r2 wander lead mothod testing to boiler 23.6 ohms and all pipe work the same . water service disconnected and gas .any thouhts

 

[sparksfly]

sorry if I repeat anything said/done.....but forget the plug in tester. Use your multimeter on all RFC's dead test end to end & also test for any cross over of RFC's r2 on cct1 to r2 cct2 (neutrals as well)etc and RFC r2 to the met with other ccts attached...anything ?
If you want to work live test at sockets removing neutral from cct ?

I suppose this is what is meant when @buzzlightyear says "To infinity and beyond" and then flies off.

 

[The Ghost]

Are the sockets surface or sunken? If sunk do they have a fly lead to the box and is the wall damp at all?

 

[buzzlightyear]

Vort all boxes are sunk in the walls the. Fly leads that are in should not show any earths it should be clear .

If I understand correctly, you have one specific RFC that has a connection to earth somewhere, despite the installation earth & bonding connections all being disconnected?

As others have mentioned, I'm not totally understanding why this is a problem? I'm assuming nothing is tripping, and you just want to know why, rather than needing to disconnect this other earth? Normally I'd just move on.

Assuming you really do need or want to know, then can you not just split the RFC into two, and find which half is still earthed. Then repeat with the earthed bit, until you narrow it down? Just like looking for any other fault on an RFC?

And when you say earthed, are you measuring a resistance to the suppliers' earth? If so, what value (from each end of the RFC)? Or did I recall seeing you are measuring Zs values on this RFC (with main earth and bonding disconnected)?

come monday, when buzz has recharged his dilithium crystals, he''ll find it in a nanomonth.

Usually it's me trying to find out why something does not compute - go Buzz go !
Perhaps confirm IR on that circuit and then isolate any backbox connections. With 23.6 Ohms it sounds like there's "an earthrod" attached .

 

[Wilko]

I have just given up for the day, sun shot from putting up outside lights last 2 days. Can I come over and lift some floor boards instead?

Buzz, what sort of walls are the metal back boxes fixed in?
what sort of building is it?

possible that a metal soil pipe is buried in the wall that's what I'm thinking. .

common brick .

i shouldnt joke if you are doing your head in, but maybe its them electric ants I read about on the dailymail earlier. apparently they get into buildings, backboxes etc and cause havoc with shorting things out??

 

[telectrix]

it's all them pesky electrons taking a stroll down.......

 

[Taylortwocities]

It’s more like

Surely its as simple as something metal, probably the incoming cold water pipe, connected via other pipes to an earthed metal appliance. Very easy to prove too.

not if the earths are connected to the c/u ,but showing earths on sockets in brick walls . and cables under wooden floors and not touching any pipe work. I have checked for that .even up stairs socket showing earths where present .

Are you sure building is not old enough to have - underground "Panic Room" / priest hole !
" Stealthy alarm system install ".
Been in attic yet?
Has it ever been the home of a radio ham or a DIYer
fearing a lightening strike !

looked under the floor boards ,
even looked for a missile bunker and any trap doors leading to some steps .
