Earth Bonding

[TimW]

I have discovered that my incoming gas and water pipes are not bonded to the CU.

The gas and water pipes are situated near to one another, but some distance from the CU.

Is it acceptable to bond the water pipe to the gas pipe and run a single bonding cable back to the CU? Or must I run two separate bonding cables, one from each pipe, back to the CU?

Hi Tim,

No problem, so long as the cable is unbroken, you can 'daisy chain' between the pipes back to MET.

Hi,
This topic was discussed here a little while ago.

Now would that be the MET inside the CU, or the MET on the incomer lead sheath?

I have seen it where the cut cables are put into a single 25mm lug and bolted down, if the bolt is taken off then the cable is still as one

Doesn't matter far as I know. Some installs will have an external earth terminal whereas in others all the earths and bonding go straight to earth bar inside the C.U.
