SWA straight into building or does it have to go through a junction box?

I've got some jobs to do at work involving running an SWA out of an attic, down the wall, and into a lean-to which is attached to the house.

I've had two thoughts - running it into a wiska via an IP65 stuffing gland and then into the house just so it looks better, or running it straight in.

I think running it straight in is fine since i'm not making it off until it's well inside the building but obviously it will just be a cable disappearing into the building with nothing around it.

Since it's not being made off until after it enters the building the wiska imo is simply decorative and doesn't serve any other function since the SWA will still be intact as it runs through.

What would you do?

  • Personally I'd prefer straight in, via a down hill sloping hole (edit down to the outside, so it drains...), mastic and carry on in  terminate in the dry inside at an accessible place where you can easily your get spanners on the glands etc. Anything else is just another potential rain trap and/or thermal bridge,
