Bonding Gas Supply in an Outbuilding

[Piratepete]

Hi Guys
Doing an EICR of a property.
The client has an outbuilding with gas and water supplies. It has it's own CU fed from the main CU in the house.
The water is bonded but the gas is not.
The water supply is underground from the house in plastic and then changes to copper which is bonded.

The gas supply comes from the house in an underground copper pipe linked to the gas pipes in the house. So, electrically, it would be subject to the bonding in the house.
But does this negate the need to bond it in the outbuilding?

Looking forward to wise words!

Cheers
Pete

No.....

It may require it.

No.....

So with no more information than a blue plastic pipe entering a building and then converting to copper you have decided it does not need bonding? Without any information as to where that copper goes or how it is installed which could make it extraneous?

Its plastic lol

No. The installation in outbuilding is copper. Read the post properly.

You need to google the definition of extraneous.

NO the incoming pipe is plastic.

NO the incoming pipe is plastic.

So what?

So what?

Being plastic, it is not an extraneous-conductive part, and does not require bonding.

Im not talking about the plastic pipe. I am talking about the copper installation in the outbuilding. You do not know that it is not extraneous without testing it first.

Think again. It is you that does not understand. I am saying the only way you can prove that copper pipework is not extraneous is by testing. You are making assumptions.

Indeed. But if testing shows it to be extraneous, the problem may be working out WHY it's extraneous and therefore WHERE it should be bonded.

That is my point. But to get to that stage, you would have to test it first, prove if it is extraneous or not and then go from there.

Well when I went to school plastic did not make a good material for conducting electricity.
