TT to pme..main bonding..

[xr4x4]

Hello all,

Following on from my other post, the DNO came out and done a Ze test, which passed.

I've been told they will send a letter asking for conformation of main bonding and for a earthing terminal to be fitted, when that is signed and sent off, they can install the PME earth.

Now, can I do this myself and what needs to be done?

Water supply comes in via plastic then to copper in the meter cupboard, so that's easy. Also running through this cupboard is a copper pipe to the hob from an external LPG bottle the other side of the wall, does this need to be bonded too?

All the other pipes, in bathroom etc have supplementary bonding.

So install a 4 or 8 way earth block near the cut out and run 2 16m2 earth cables (I know it's too big but I have a reel of it) to the water and gas pipes via pipe earth clamps?

Yep. The gas will definately need bonding within 600mm of the point of entry to your property.

Does the water come in in plastic and then change to copper inside the property?

Yup, comes in plastic, then place is plumbed fully copper.

I can do all this myself and consider myself competent but will they be happy with this, am I allowed basically!!

Yes, definitely not notifiable...

...and you can test with your new meter, so all above board.

I would say you probably dont need to bond the water, but it's going to save any arguments later on if it's done.

I'd say you're competent to run and connect the bonding, but I'm not quite sure whether the DNO will want something signed by an electrician, or if it's just a case of get a signature to pass the buck if anything happens as a result of inadequate bonding.

Ok, thanks.

I'll bond the water anyway.

I'll wait untill the letter comes through and see what it says first.

They did say they would do a few quick visual checks first.
