No earth bonding to the water.

[Goody]

Been to a property and noticed that the main earth connection to the CU MET is only by a 2.5 mm blue cable. Now, that’s an as easy-peasy job to fix but the trouble is, a 10 mm cable connects only the gas and no sight of bonding to the water. It’s a non RCD board with only MCB’s and couldn’t see “Supplementary Equipotential Bonding” anywhere.

The floor in the switch cupboard is concrete and rest of the house is laminated, how am I going to do this?

2.5 mm Blue cable for the main earth.

Gas & water pipes to the boiler.

Trunking? Hideously ugly, I know but if the cable run is that difficult it could be your only option

I might be being picky here buddy but dont foget its either earthing OR bonding.......they both perform different functions........

id say test the pipe see if could be bonded elsewhere..

well do the bonding thats easy enough or put in rcd or rcbo's
where is the water to where the fuse board is

Is the incoming water supply in a metal pipe? if so could you run the main water bond on the outside wall?
