SWA Cavity Wall Exit

mackatoon · May 17, 2021

Hi guys. Just after some advice on what you think the best way of getting swa through a cavity wall.

Do you use just use T&E, conduit and wiska boxes before transfering to swa or just go straight through with the SWA? What do you think the tidiest method is?

I only ask as I'm running power to a hot tub and the swa cable will need to come out above the front door so easily visible.

Thanks in advance

I always take it to the board, and usually put a suitably sized pipe in the wall as a sleeve

I have recently run a supply to a shed and glanded the SWA in to one of these which was sprayed black,

with a rubber gasket over the top.

Cut a hole out the back of the conduit box and thread some plastic or steel conduit on the back and poke throught the wall. Can then run the cores in conduit/trunking etc back to the board.

Looks tidier than a wiska box IMO

My personal preference is to keep the swa cable continuous, especially if it’s a simple run and small swa cable can easily be run through the house.

I always try to keep the swa going straight to the board. Don't really understand why you'd use twin and earth for the first bit it's just an extra joint on the cable unless it is already there.
