Is it possible to terminate SWA inside this box?

Is it possible to connect SWA to 2.5 mm mains inside this box?

Yes, but I wouldn't. It doesn't look a very good quality box and will be likely to flex and fail under the weight of the swa.

Yes, if it's external you will require external SWA glands.

Hi. I know I need to use SWA glands; the problem is these weird rubber bungs that fill the holes in the junction box. If I remove the bung entirely, the hole is too large and I can't seem to do it with the bung either due to the space it takes up around the threads on the nozzle of the gland kit.

Did you look at BAS link above
you throw the bungs away, and just fit the gland assuming there 20mm holes and glands
Using plastic may require extra work regarding earthing

What diameter is the knock-out, it's not normally a problem, once banjo and gland nuts are tightened up.

There are better ones available.

Better off with a normal GEWISS enclosure thats not pre-drilled and making your own holes for the glands with a 20 mm hole cutter.
Although i am rather liking the Wiska boxes after a demo at a local wholeslaers brekky morning.

I did look at BAS' link? But it doesn't tell me anything new - the situation is different there, because it uses a box with just the right size hole.

If I pretend that the holes are 20 mm (they are in fact 28 mm), then the box won't be waterproof anymore? Sure, the chances of water splashing up into the gap is slim, but that's not the point, right?

With the bung removed, the entire gland kit (sans boot) fits through the hole:

Then use a proper box.

Then use a proper metal box.

Edited to make for easy earthing

You failed to mention that earlier
You have it sounds a box with PG size holes, adapters will most likely cost more than the correct box
