Gas Water bonding

528.3.3 Where an electrical service is to be located in close proximity to one or more non-electrical services it shall be so arranged that any foreseeable operation carried out on the other services will not cause damage to the electrical service or the converse.

NOTE: This may be achieved by:
(i) suitable spacing between the services, or
(ii) the use of mechanical or thermal shielding

and this applies to what and how?

Make sense to me.


Mr electrician installs 1 main bonding conductor from db to gas, to water.
Mr gasman moves meter and in the process throws away the pipework originally bonded.
Now if mr electrician cut the cable, or put 2 x lugs in the clamp, what is stopping mr gasman from taking them off and thinking the job of re-instating belongs to mr electrician.
However if the cable was not cut then mr gasman would theoretically just take it off the clamp, leaving the water bond perfectly sound.
Unless of course mr gasman is a green&yellow cable cutting plonker

says "proximity to", not "connected to".. so no cable tieing it to gas pipes..

I see where you're comming from, but I think this is more to do with Mr Plumber melting a wire with a blowtorch when soldering a pipe and such..

Well mr plumber appears to be using nothing but plastic these days when will things get easier for the sparkie

if you use a decent crimper then yes, it's mechanically sound.. more so than wrapping a conductor under a screw..

you put 1mm in red crimps designed for 1.5mm, 4mm in yellows for up to 6mm so 20mm into a 25mm crimp should be fine..

Red crimps are not designed just for 1.5mm.
They are designed to accept a range of sizes between, iirc red are between 0.25mm and 1.6mm. Similarly with the blue and yellow crimps they are not for a specific size.
When crimps have the size stamped on them then I cannot see how they can be deemed suitable for a range of sizes, otherwise would they not have the range size stamped on them?
