I would like to change the electricity supply to my detached garage. The garage is about 1 meter away from the house.
The house was rewired 12 months ago to 17th edition. The kitchen is on its own ring - 10 sockets, 6 of which are almost never used. Its not possible to run SWA all the way from the CU, so I want to use kitchen ring.
My plan is to put a suitable junction box to extend a leg of the ring main down the inside to about 50 cm from the floor. Drill through the outside wall run T&E into the back of an external SWA junction box. Then run 4mm 3 core SWA cable down the outside wall (clipped) into the ground to a depth of 45 cm, then take it across to the garage (underground w/ warning tape 15 cm below ground level) and come up on the inside of the single block garage wall. Run the SWA up the wall (clipped) and connect to garage CU.
Does this seem OK?
