Minor works and bonding

[ianmacd]

Hi All

Just looked at a job where they want a fused spur outlet in a garage for an electric garage door. Was looking good as someone had previously extended the ring to 2 new sockets and used a JB within a meter of the new outlet so was going to spur form that. Then I checked out the bonding.

Gas bonding was missing. Apparently had a meter replaced a while ago but it never looks like it was there. The flexible pipe from the meter goes straight into a T piece so I am guessing it will need 2 clamps on each pipe just after the T? No real issue here.

Water is bonded (kinda). Seems to be in 4mm to the stopcock about 8m away (under the floor). The stopcock has been boxed in as part of a fake stud wall with a small flap to get to the tap but there is no way to get to the bonding clamp without ripping the wall apart/down. Can this be left and just noted on the MWC or will it need some major demolition work to get it up to 17th?

The supply is TN-S. I suspect if its a problem with the water bonding they will say leave it and suspect will get someone in to put in a spur unofficially (if you know what I mean).

I was hoping to use this as a backup for my ELECSA assessment (will already have 1 notifiable + EIC and 1 Minor with MWC) so I need to be able to justify any action taken.

Thanks for any advice.

Ian.

Gas should be bonded in 1 place, before any branches. you will need to upgrade earthing to 10mm to both gas and water. dont forget you may need to RCD your work depending on cable runs etc, or if the garage door spec says it needs RCD

RCD already in place on CCU (I suspect it has been replaced in the last few years but its not a split one and no EIC ).

I didn't think we could bond to the flexible metal pipe from the gas meter? There is very little room to bond before the T otherwise (well the flex pipe connects directly to the T).

So big mess in the kitchen to get to the stopcock then?

Thanks.

the flexible pipe is usually on the inlet to the gas meter?

Maybe bond both sides of tee if its conex. if its sweated, bond one side

you will need access to stopcock, but to replace cable, you may be able to tie onto one end and pull through new cable

Not sure pulling it will work cos it seemed to be heading into a concrete slab. Think I may have to find another route for it.

Thanks.

outside?

I think that may have to the the option for now but that's going to be a long old run and for sure they will not like it (nice green and yellow cable around the house). Getting at it is also an issue cos someone built a box of at least 25mm wood all around the stopcock and the rest of the pipe is inside the wall/riser.

Can reroute it in the future as they suggested changing the laminate floor in the bathroom so could get access then and reroute below the floor.

Fun Fun Fun.
