Double insulated single core cable on outside of house to resolve earth bonding

Alan B

Hi I have to resolve an earth bonding issue where the incoming water supply pipe is cast iron and enters the house on the opposite side to the CU.

It's sold floors, beams showing although there may be a roof void but the easiest way is round the outside. I am considering using 10mm or 16m single core double insulated cable, blue or brown sleeved to green/yellow.

 

I am looking at this as a conduit run is a bit unsightly and takes time, just thinking there must be a better solution. Whats your opinion on the solution and any other ideas?

Thanks

    All thanks for your suggestions. I will give the customer the choice of just the cable or run it in conduit. I will probably use  linian super clips to make a neat job of it.

    Only needed in my opinion if the cable is to be affixed at high level and may impede egress in case of fire or other emergency inside a building. Outside it is not so much of a problem, especially if clipped at low level.  I think that the worry in a fire is “premature collapse”.

    Edit. Add.  Oh!, and never give customers too many option choices  as it can confuse them. Two options is plenty. Normally customers are looking for a neat job and an acceptable price. If you overestimate you may lose a job. “Keep it simple” often wins work.
