AT RISK WATER MAIN EARTH BONDING THROUGH METER BOX BACK PLATE

[ShaunCorbs]

Read what I said again please - if the hole in the wall is filled in.

Obviously the cable needs re-routing first and I'm not arguing otherwise. Would you, speaking seriously, replace the entire meter box to remedy a small hole in the back that could be patched up? Reason I ask is many gas boxes of a certain age have damaged doors or rodent damage and landlord's certificate inspections don't seem to care too much, which I assumed was because there wasn't a path to the inside. Is this wrong?


Who's info is irrelevant?

Yes no different to the gas pipe not being sealed the spigot / manufacturer holes are there for a reason

Can you guarantee that hold will stay sealed / tight to the cavity just by putting a blob on it

A broken door - if there’s gas escape, chances of entering the building are slim.

A siliconed hole - whereby the hole into the fabric of the building won’t necessarily be sealed - chances are more likely (a risk).

Only similar to the material used to seal the pipe to the box coming away - and it happens when they've used putty.

Appreciate everybody taking time to comment by the way folks thanks very much everyone.

Hiu Shaun,

I agree with your point: a blob would be a bodge and a proper repair would be more laborious.

However, if the wall were mortared up AND the hole in the plastic repaired using Araldite (or better still actually glue a patch over the hole), I think it's guaranteed no gas will escape to the cavity. As an RGI, would you be happy with this or is it still a no no?

 

[chris123]

Does anyone have any recommendations or suggestions for a sleeve for the earth cable so it can be put safely through the cavity wall near to the gas meter box?

 

[Ric2013]

Assuming it's outside the box, and it's going straight across the cavity, I'd be interested to know whether electrical regulations strictly require a sleeve? If not, then I'd suggest any common sense material (offcut of pipe or hose) would do as they would class as a cable installation aid.

right thanks, just with it being probably near the meter installation thought it would be for the best. cemented in place and with a good bit of non setting compound perhaps in the end. they suggested 20mm conduit on the electrician forum

 

[ShaunCorbs]

20mm conduit or a bit of 15mm copper either acceptable

Thanks Shaun.

Today the company have replied to a recent initial email I sent with the photos saying:

"Hi,I have returned from annual leave this morning , I will investigate this and get back to you when I have more information. Are you happy for us to seal the wire? Thank you"

I havent replied with an alternative yet. Just wanted to formulate the best counter suggestion.

Cheers

I wouldn’t want them to as they wouldn’t be able to guarantee it also you might have a service later on and someone flags it up

yes thanks that's what I thought too, about follow up problems

Yep also it’s modifying the meter box technically as it’s not an approved hole so needs a new meter box and the earth moving externally or via an approved entry

I found this thread on the Electricians forum, I was not aware us sparks could not drill a hole in the meter box, but now I know, it makes sense. Maybe I'm the only spark that does not know this, but I doubt it. There is nothing in our regs, and we are the ones fitting the bonding, so the IET should include this in our regs so we don't continue to do this. But as commented previously, there must be loads of boxes that do not comply. Replacing the whole box seems over the top if this is the only non compliance.
Looking at the regs snip, it seems to me that the requirement is to make the rear part of the box air tight. I'm thinking a Wylex Membrane Cable Entry gland should be sufficient. I know the Wiska membrane glands are IP66, I assume Wylex will be the same. So this could be an easy fix ?

 

[ShaunCorbs]

Problem is it has to be tested to be air tight tbh these days I don’t know why there isn’t a m20 threaded hole so you could put a gland in it etc

Yeah I agree, it’s all about proof.

M20 thread Sounds like the perfect solution.

I was just thinking we could just drill and use compression gland, but often the spark arrives after all done, so we could not get a nut on.

Although most import thing is education.

Hence why they drill a hole where they can get too it’s one of them needs more communication on new builds

External box tested air tight? Is this real? Our gas meter cupboard door doesn’t even seal properly😁

Yes in regards to leakage into the cavity

every day is a learning day.

shame the gas regs people and the electrical regs people cant agree on consistency of wording of regs 😊

Classic one is the new ones 18th am3 I think, if poly / plastic incoming yours doesn’t require to have sup bonding where as ours stat you must 😀

This day and age you would think they would get together and have a meeting
