New Gas meter fitted at factory - Earth Bonding Q

[thegruf]

Hi all,

Just has a new gas meter fitted at our factory.

Was left an advice notice that there was no earth bond within 600mm of meter outlet.

The problem with this is the meter is 20 meters away from the building in a little 1970s hut all on its own with a paved parking area in between. The pipework is 50mm steel with yellow plastic covering.

How the heck I am supposed to get that bonded?
(And anyway I thought bonding was at point of entry to the building?)

Sorry if this is a repeatish thread but I could not find quite the same example and guess not many have the meter as remote as this from the property.
Advice appreciated as always, thankyou.

You right Gas pipe should be bonded were it enters the building Its Reg 544.1.2 in the green regs book sorry don't have the yellow one to hand

 

[Plonker 3]

Is it a extraneous conductive part?

 

[Pete999]

Bond it where it enters the building

 

[thegruf]

quick replies - thanks folks.

That's the point though - it is bonded with 10mm where it enters the building which I thought was correct.
But the Transco chap (or whoever it was that changed the meter) left a Warning/Advice Notice stating "No earth bond within 600mm of meter outlet".

Technically it is an extraneous conductive part as it is a metal pipe.

Am I right to consider that as most meters are within/on the building wall that the meter chap is just expecting to see an earth bond there close to the meter, and in this case he is in error re the bonding which in this case is distant from the meter but is present where the pipe enters the building.

it's because BG like to bond to the meter, even if it's in next door's outside bog. they should read wiring regs instead of the daily mirror. you're right. he's wrong.

 

[thegruf]

haha.

Bit small for an outside khazi, maybe for dwarves, but point taken - thanks.

Didn't want to get this wrong in case was different for factories instead of residential.

(reminds me of the time I put a new boiler in my house and got a gas safe bloke out to certify it, showed him the calcs I had done to make sure the pressure drop was okay for the regs. He thought I was utterly mad and had "never seen anyone do that before", just did a static leak test (no dynamic pressure drop test like he was supposed to) and b*ggered off with rather more £££ than I thought he was worth!

wiring regs are the same reguardless of where it is unless it is overruled by another reg e.g. for explosive atmospheres or in control systems and machinery

Which demonstrates that his knowledge is poor BUT at least its highlighted as an issue for somebody to resolve.

Maybe the OP should get BG to quote and see what shyte they come up with....

Just a thought....are there any electrics in this little 1970's hut?

 

[jackhammerJIM]

Whats the earthing system of the factory ?

Electrics? - not even big enough for a candle

There again maybe a candle wouldn't be the best thing :93:

BG?

Nooooooo ... erm endof

BT?

Noooooooooooooooooooooooooooooooooooooo ... definitely endof

Honest answer is I dont know for sure as never had much work done at this site

best guess would be TN–C–S /PME

 

[jackhammerJIM]

and how big is the supply ?

 

[Buckfast]

and how big is the supply ?

I can see where this is going. Is there a neutral involved ?

 

[jackhammerJIM]

it could be a small factory . then again :rolleyes4:

 

[7029 dave]

You thinking 35mm. Its possible lol

 

[jackhammerJIM]

For the incomer or bonding ???

 

[7029 dave]

Bonding, ive seen it 200amp supply.

could be bigger Dave . When the word factory springs up i can't help think of 400mm 4 core armoureds

Absolutely 50mm plus. Depends on distance and spec, overkill springs to mind though with some.

 

[mattg4321]

I had a similar thing at my house when my meter needed replacing. Told him the reg specified 'on entry to building'. He disagreed. I told him to do one.

(once he'd turned my gas back on!)

 

[emacleod]

A plumber I worked with said the same. The gas regs say it has to be at the meter. He put on his gas cert that it didn't comply being at point of entry.

 

[thegruf]

only 100A/phase - nothing exciting sorry to disappoint

please tell me you got the units mixed on that

Yep I think they've had some 'training' on this. So now when they change a meter, instead of ripping off the earth clamp & cable and leave it dangling in the wind, they're demanding to see the camp & earth on their gas pipe in the meter box.
