Gas & Water bonding

[Jay Sparks]

Hi Guys,

Is there a reg that says you can not bond the water and gas using the same 10mm cable?

i.e. A piece of 10mm cable from the board to the water stop tap the from there to the gas meter about 2 foot away.

If you came accross this on a PIR what code would you give?

Cheers in advance.

Jay

as far as i was aware this is quite acceptable so long as the sheath is removed without breaking the conductor

You can bond it however you like but you need to take into accout the earthing system. It is generally agreed that seperate services earthed by the same conductor must be unbroken

As the other guys have said no problem as long as the earth has not been cut ,if it has been cut then i would code 2 , requires improvement , i know the other guys might say code 4 which you could also use

if it is not unbroken, could it not be re-terminated, unbroken at say , the water, and the piece to the gas thru crimped ?

 

[Jay Sparks]

Ok so basically it goes to the water tap on a clamp, then from the same clamp with another piece of 10mm to the gas clamp. This would be classed as broken? So as nick says, I will code 2 it as I cant find owt in the regs to say how it should be. But as you guys have said it needs to be one piece with only the sheeth cut.

Cheers

The reg you need is 528.3.3 p 109 have a read as it is not an obvious one.

EEEEEHHHH????? Just read it and what a head scratcher. Cant see how this relates to the bonding though. It sounds like it relates to maybe a new mains board being installed close to gas &/or water services but not too close so that when gas/water services are being maintained or worked on that it does not damage the electrical mains board.
Or am I totally missing the point?

The reg no. is 411.3.1.2 pg. 46. But no mention of seperate bonds.

Im using a mains board as an example it could relate to and electrical service.

 

[Sintra]

Any electrical service could be bond to gas and water which is connected to a non electrical service. My interpretation of the reg I stated is that if a plumber removes the water pipe and replaces in plastic then there is no disruption to the bond to the gas main or vice versa. I would be interested to hear others views on this.

agree with sintra on that. can't see any other reason for it

I see where your coming from. They should have wrote it how you've explained it. How easy was that. Im gonna send a copy of the regs to Dr. Steven Hawkins and see if he understands it. I must say though, it is open to interprutation and can be missleading.

Cheers
