Extraneous parts

[tigerpaul]

Supposing I have my Main Incomer (4c70mm2) at one side of a very large warehouse.

My incoming water is on the far side.

My Main Earthing bond (35mm2) is from the incomer to the M.E.T.

I am going to equipotential bond my Structural steel close to the M.E.T. (25mm2)

Can I then come off the Structural steel on the far side to bond to the water incomer?

Or would I need to run a seperate 25mil all the way from the M.E.T.?

How many other services could I use the Structural steel to bond in the same way? Is this acceptable?

Thanks in advance!

Surprised no-ones clocked this one...
All incoming services should have their own dedicated bond run to the MET.
Reasoning behind it is that say for whatever reason you lost your MET connection to the structure, in your situation by proxy you would also lose protection on the service, in this case the water pipe.
Hope this helps
