Unsure about main bonding

[golfpaul]

Hello.

Been asked to add bonding to gas, as British Gas has advised customer gas has no bonding.




Gas meter shows no signs of bonding, cannot see bonding to water either.




They have a shower cu which has a 10mm2 earth to it from the main earthing terminal - no other earth cables leave the MET which leads me to believe that neither gas or water are bonded...however:


With this 10mm2 from the shower connected to the MET, i get 0.00 to gas and 0.00 to water.


With the 10mm2 disconnected, i get a reading of 80v, and tester will not continue with continuity test.


There is a clamp of some sort near the stoptap, with bare cable running through the garage, where it appears to be broken in parts.




Does the gas and water need bonding, seeing as though i get a 0.00 with the shower cu 10mm2 connected to the MET.
And why do i get 80v on shower cu 10mm2?

Ta.

I'd stick your tin hat on and dig a trench for this question fella.

Yes it does and just a point 0.00 what https://www.youtube.com/watch?v=rnvNfI__kYU

 

[telectrix]

yes... gas and water need bonding. that's only part of it. what a bloody abortion.

Does the gas and water need bonding,

Oh No Gasp!!

I don't mean does it need bonding, but could it already be bonded given the results.

Hi,

I usually get into trouble when I mention Bonding on here, But this is my take on it anyway.
You say there is no evidence of any Bonding, but you get a reading to the MET from the Gas/Water pipes. Are they extraneous, that's the question you need to answer.
The reading you are getting is probally where there is an earth connection to a Boiler or Immersion , or something similar; and as we all know Earthing is not Bonding- they have different functions.

Finally, that set up in your picture looks a bit of a mess.

Regards.

a bit of a mess? it's a total shambles. a 5 year old could have done better. @OP. do the bonding as in BS7671, then sort that rat's nest out.

I don't mean does it need bonding, but could it already be bonded given the results.

But you said there was only one earth wire evident, so it cannot be, can it??

 

[Guest55]

tin hats wont save the OP from a right royal flaming on this query.

the gas pipe entering the house is metal yes ?

if it was , i wouldnt be messing around with continuity tests looking for some excuse to just leave it like it is..

and the piddling bit of old earth wire in the last photo doesnt look like 10 or even 6mm to me.

course it bloody needs bonding , cant believe theres any doubt or discussion.

clearly not , given that earlier said was..........

no other earth cables leave the MET.

10mm2 HE or 10mm2 bunker buster???

 

[golfpaul]

Thanks all!!

I was more unsure about the reading despite no visible bonding being present - and the voltage indicated.

Thanks for the tin hat MDJ

Maybe just how I've read this, also can't see the pic too well but I'm wondering. ..
You say no other wires coming from met other than 10mm to shower cu?
Anything going to the main CU???

Hello.

Been asked to add bonding to gas, as British Gas has advised customer gas has no bonding.

how did BG advise this? Via EICR, or did they do some electrical work there?

 

[tony mc]

Most likely a meter reader or a BG worker touting for business!!!

My next door neighbour has just had his gas meter moved and they reconnected the bond to the new position, it was fitted that good that the clamp slid down the pipe and the cable dropped out. They had cut the cable as the meter was nearer the CU and in doing so the crimp was no more and they bodged the connection !!

 

[percysybil]

deep breath and sort it in accordance with BS7671 or walk away from the job would be my advice pal...

 

[trev]

But you said there was only one earth wire evident, so it cannot be, can it??

GASP! You mean.....The one cable could be continuous to both services?
GASP!

 

[Guest77]

GASP! You mean.....The one cable could be continuous to both services?
GASP!

No the one cable was the shower earth, no earth visible at gas or water

 

[trev]

Oh. Gasp! I had the completely wrong idea!
My apology is due.

[telectrix]

can't knock weston's. the real ale version of cider. how come no alcohol? don't say doctor's orders. same doctors prescribed thalidomide.
