Hi,
I'm planning to redo my shed electrics as I've just put in a new shed!
The old set up was 2.5mm 3 core SWA (approx 6m run) fed from a outdoor socket against the house which was run to the shed (through the T&G cladding), into a RCD and fused down to 16amp to supply a light and double socket.
I was never a fan of how the SWA was tacked into the shed, it looks unsightly so I'm wanting to terminate it properly.
My thoughts are to terminate the SWA in a weatherproof adaptable box on the outside of the shed and then drill out the back of the box and feed a cable through the shed T&G cladding and up to the rcd/fcu as before.
My concern is how to maintain the IP rating of the box once the back has been drilled out - should I be using a stuffing gland which would essentially be horizontal through the shed wall and feed 2.5mm flex (or T+E?) in there for the internal shed wiring or should I be using some sort of grommet?
Or am I over thinking this and I should just run mastic around the outside of the box?
Thanks!
