Gas Bonding??

[ShaneD]

Hi all,
Upgrading a consumer unit and bonding for a customer and would welcome any ideas.

Domestic property TN-S 100A incomer, run in a new 10mm bond to water and there is already a 10mm in the MET which I assumed to be bonding for the gas.

Gas meter is out the front of the house in a cupboard, no clamp there, no probs I'll find it where the pipework enters the house. Wrong!

I have taken down lots of boxwork, coving etc around boiler and gas fire and can
I used a wander lead to test continuity from the 10mm earth cable, removed from the MET, to gas pipework at the meter and before the regulator in the boiler and got low resistance continuity 0.09 ohms.

How would it be best to record this on EIC?

Any advice appreciated

Shane.

Acceptable result. It is effectively bonded.

Record it as so and state 'not inspected' and 'cannot be inspected' blah blah and sleep happy in the knowledge that you have done your utmost.

No visible bond to gas service
Gas pipe reading to MET verified and acceptable

Thanks for replies,
I just realised 0.09 ohms reading was beofre nulling the wanderlead, doh! actual reading is 0.02 ohms. I guess this is better.

Cheers

Seeing as this reading is below the 0.05 stated in ol'red, then the deviation of the position of the clamp can be noted on the cert.

shouldent all bonding clamps be accessable for inspection and testing?
