The (single) garage is only a couple of metres from the house and I have 3 core SWA (2.5mm) running under the path into the garage. According to the TLC calculator this will give up to 5kW power.
On the house side I have not run the SWA all the way to the CU and need to connect it to 2.5 mm T&E somehow. The SWA runs up a wall and will be boxed in so I had planned just putting a blanking plate on the plasterboard allowing access to the cable join. Is it feasible to use choccy blocks for this?
The T&E will run to a spare way on the CU (not RCD protected) and will have a 2-way CU in the garage. The garage will only have a lighting circuit and one (maybe two) double power sockets.
I had planned to export the house earth using 1 core of the SWA.
Presumably at the join to T&E the outer steel protection should be cut away completely?
At the garage end I might try and take the SWA directly into the CU but if this is awkward I could join it to some T&E just before the CU.
Any comments gratefully welcomed.
