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.

Bonding gas pipe has led to complications . Most AHJ's don't require the gas , But only require the water main

What country are you in?

AHJ; Authority Housing Jurisdiction?

Is a term for inspection. Who says you have to bond the gas pipe .

A very simple test will tell you whether the gas pipe needs to be bonded or not. My money is on it needing it, they usually do. Do you know how to carry out this test?

That's not true it is not needed And it could arc the metal gas pipe make a hole in it and cause an explosion

That is so unlikely as to be ridiculous mate, just about every building in this country which has a metal gas main entering it will have bonding to it and those that don't probably need it. If you think that this is a risk please explain where this information comes from so we can debate it.
Do you actually know the reason why services are equipotentially bonded or is it something that we do just for ****s and giggles so that we can waste some of our customers' money?

Thinking about this and it has to be a wind up, no one claiming to be electrically qualified, even at the most basic level of 5 week wondery could believe this.
Surely?

I was thinking the same thing after i'd posted. But then again nothing surprises me anymore with these wannabe chancers....

The OP or wind up merchant hasn't bothered to say what he is what quals and experience he has, which lends to to think wind up

Definitely a USA term.

I know the original question was about bonding, but where is the RCD protection for the shower circuit?
