Hi guys,
With respect to green hornet's answer, I'd like a couple more opinions on this scenario please.
I'm copying and pasting from the eleectricians talk 'elecsa' thread, hopefully I can put it together like a jigsaw puzzle Pray
Cheers in advance.
Had my assessment today... had a non conformance!
Basically took him to see a small job (utility room ext, SWA to small cu, 1 ring 3 outlets, 1 light 2 outlets) and I'd changed the CU in main house. I & T and cert, building notice already paid due to builders, no probs.
Basically the kitchen had been altered since I was there, gas meter also moved, so main bonds were no longer visible at clamp, kitchen end.
Do you think it will be alright if I run a (single) 10mm earth to external white box gas meter (and loop off to new sink/hot/cold directly behind white box inside) from my new mini CU in the utility room, that is fed by a 10mm 3 core SWA from main CU?
Effectively I'm proposing to use the 10mm earth core of the SWA for the first part of the run of a new main bond, whilst also using it to supply the earth path for the mini CU.
2nd part of the run to be a new 10mm earth (single).
I hear you, I just thought it was arguable whether the SWA is a circuit in it's own right, or just no more than meter tails effectively.
It could of course be argued that every installation is just ONE circuit seeing as there is a main fuse covering all branches from... :|
I now can't tell what has happened to the gas meter end of that particular main bond, as it's lost behind the new kitchen units, and they would require dismantling to gain access.
The water main bond is also in this area, I have in fact since my first post managed to blindly grab this and pull it, unfortunately i've pulled it clean out, I don't think the kitchen fitters had clamped it on properly. To further complicate things this is in the complete opposite corner of the room to the sink position now, with a large conservatory to go around if I take that route.

Thanks Green Hornet.Short answer would be no.Main bonding should be stright through to the main earthing terminal for the instalation.
What you propose is to "piggy back" the bonding.
If you do that you have connected the bonding to a cpc of a circuit.
