Gas Bond Yes or No?

[James Croxford]

I have just carried out an EICR and the only C1 defect I found was no 10mm bond to the gas. As this is not a fixed gas feed but only a gas cylinder I guess this still requires an earth bond from the DB? (feeds hob only)

My next question is, if the rubber hose from the cylinder was to continue in plastic all the way to the hob would it then be exempt from having to have an earth bond at the cylinder?

Here's a picture I took yesterday....

Have you checked to see if it is in fact an extraneous conductive part by means of testing.

Haha, very funny, from the wording it looks like you are asking do you need to bond a rubber or plastic pipe:lol:

 

[James Croxford]

......

 

[James Croxford]

The pipe work passes continuity (R2 lead test) as the hob is earthed through the fused spur. This would still be classed as an extraneous conductive part, correct?

 

[GLENNSPARK]

and further more...sinse when has an absense of main bonding been a ....`cat 1`..whatever the hell that is..

i think you mean code 1..

still...not a c1......is it...

That is not the correct method to determine if a service is extraneous or not apart from the need for a wander lead

No.

To test whether it is extraneous you must isolate the pipe (disconnect) and IR test it to the MET.
As you are doing an EICR and you will not want to do this perhaps you should assume that it was deemed not extraneous when fitted because it doesn't go to earth.

P.s. it is 'earthED (equipotential) bonding' not 'earth bonding' - subtle difference.

but if he isn`t sure (visual)...then he proves it by means of IR & wander lead....doesn`t he...

 

[Geoffsd]

Isn't that what I said?

He's doing an EICR.

No help doing an IR with it connected to the hob and CPC.

Would he test or be worried by an outside tap?

well...alls i can say is this:

if he is carrying out ECRs...but cant grasp how to prove extranious (method used)..

well, what more can i say..

I re-wired a house a few years ago out in the sticks with the gas set up like this. Didn't bond, Didn't need to.

I'm not sure about the regs. regarding LPG, but if this were Natural Gas and you ran it in plastic you would have you balls cut off - and rightly so !!

Running gas in properties through non-metallic pipework fell out of favour just after the Ronan Point disaster !! ( Google that one sometime! )

 

[Guest55]

1. missing bonding is a C2 , as glenn correctly infered.

2. a gas bottle sat on the floor is not an extraneous part in any way and doesnt not require bonding , and neither does the pipe which isnt even touching the ground.

seems to me like some poor home owner has recieved a failed inspection to which they did not deserve , which is all down to p*ss poor understanding of basic principles.

 

[ChrisElectrical88]

Plus the fact the gas bottle thingy is only connected to the pipe with rubber, which if rubber is a conductor I have made a massive **** up in some earth free environments!

James,
As the guys have already stated................bonding the pipework and the gas bottle would be the perfect example of 'introducing' a hazard by unnecessary bonding.
An earth fault on the system would /probably raise said pipework and cylinder to mains voltage(think aluminium double glazing in past years) and the poor sod that comes to change the bottle will be it's path to earth.........probably

Brief and to the point. Quite restrained and a bit disappointing really. ... Has you Tiger tank broken down an left you using your stand-by water pistol???

Ah, the Sturmgeschütz III was a fine fighting machine, given the choice a brilliant selection for a tank commander to see through an ambush or a meeting engagement. The Jagdpanzer IV however with its better armour arrangement, longer range and faster speed made it a great weapon for blitzkrieg!

Personally however, with the freedom to choose from either side the tank I would most want to be in would have to be either a Hetzer or a Hellcat. Shoot and scoot is and always has been my MO!

Probably why I often like to bodge it and scarper

 

[GLENNSPARK]

i think its a captured tank is that...as these are german soldiers stood around it...

Aye?? ........... I always thought there was summat funny aboot Granddad.

i prefer to stand there and fight it out:

Naaa, hit and move.. Hit and move. Stick around like a concrete block you'll get shredded eventually.

your grandad? i thought it was you.

What a beautiful piccie !!

I have one of a WW1 Dreadnought sailing down the Tyne on its way to its sea trials after being built at the famous Armstrong's works.

Bloody magnificent sight - all smoke, might and majesty. I'm reminded of Tidyboiler every time I see it.
