[QUOTE="springcrocus, post: 25161, member: 935"] I will be taking a run of 6mm 3-core SWA down an outside wall and into a trench to supply a summer house at the bottom of the garden. I am thinking of protecting the cable at the point it enters the ground (and at the other end, on exit) by placing the cable in a hockey-stick shaped piece of gas barrel or some other kind of tube. The opening of the tube would be sealed with a good dollop of sealant and/or a SWA boot. :) Reasoning behind this is to protect the cable from lawnmower wheels etc. :_| My questions are: Would you bother or am I being too fussy? If you would, what sort of pipe would you use and how high above ground level would you set the top of the pipe? Note for Steps: The supply is TNS and I will be taking an earth connection from the house, connecting the armour at the house end but not at the shed end. Wondering about banging a rod in at the other end as well. ]:) [/QUOTE]
