Now i am pulling my hair out

[buzzlightyear]

Just put a new cu in started testing .so here it goes start doing rfc line 0.33 nn 0.32 cpc 0.55
Ins all good now this a split load
Dis the cpc what i was working on and now showing earths in and are out so theor is no parallall paths has far that i can see the main earth is out but showing earths all water and gas have been disconnected

If you connect the gas and the water what are the *readings?

















*I may be taking the pee pee..........

 

[buzzlightyear]

not conneted the gas.water.
Met. Earthing. Disconnected. But showing earths sockets .

 

[Ian1981]

I always wondered if buzz had hair under that headgear?

 

[buzzlightyear]

Unless his house is one big earth rod .but how the hell it showing earths if no earths are in play only on the sockets .

 

[Flanders]

Ring circuit cable damaged on central heating pipe cpc now touching heating pipes immersion heater or boiler sending earth path back to sockets . Just an idea

 

[buzzlightyear]

There is three ring circuits all showing the same problum.

 

[westward10]

Have you got any old imperial cables in situ which have larger csa cpcs.

[buzzlightyear]

No westy all 2.5 frm cables in all three rings are the same prob all earths disconnected but showing earths .

 

[westward10]

Another possibility is the existing rings have been extended to enable more outlets, the lines and neutrals are incorporated into the existing ring but not the cpcs not so they have effectively become a figure of eight.

 

[Flanders]

Have you tested between the ring cpc and other posible earth sorces such as pipes and other cpcs

 

[buzzlightyear]

No dout that dis the earth to the cu showing earths are in play .i have three socket and see pluged in showing earths.

What exactly is the problem here?

 

[buzzlightyear]

The problum is earths not in the cu but showing on the plug in testers on all 3 frm and no earths on the met or gas or water .

Metal back boxes connected to or touching steel frame partition walls ?

 

[Gavin John Hyde]

Any metal stud work in the property? a lot of other trades use the metal stuff rather than timber these days. often find boxes joined to the metal studwork.
Also any chance of damp or moisture in the walls between back boxes if they have the cpc in them?
Came across something similar when I was still at college and just started working. property had a bad damp problem that once sorted out resolved the irregular readings??
