Earthing/Bonding advise please

D4G
Hi all, i'm after some advise and thought this would be the best place to ask ?


I have a supply cable to an out building, currently in 16mm T&E and an underground copper water supply also in the out building.  The pipe currently has no bonding.

I want to upgrade the cable to the out building.  Would a 16mm 3 core SWA be suitable, using the 3rd core as a combined CPC and bonding conductor.


Main supply to house is overhead assumed to be TNS due to the supply cable being Split Concentric....



Thanks in advance

    Thanks for you time Andy, much appreciated.


    The old T&E is unsightly as it runs around the middle of the house, I am clipping the SWA around the bottom of the house and a short underground run (about 1.5 meters) under some flags to the out building.  Also the cable was selected with a good safety margin.

    I'll stick with this idea as I have the materials and not a fan of TT.

    Not an option to replace pipe for plastic as it comes in under a concrete floor.

    Is it common to find unbonded extraneous conductors? 


    Another question, what size should the links be from the SWA glands to the earth terminal?


    Thanks again.
