Help please.
Firstly the kit I'm using.
Wiska 607 box. 25mm knockouts.
4mm 3 core swa.
20s gland
Wiska 25-20mm reducer
Secondly the issue.
The 20s gland is to short to show thread through the reducer, this means I can't fit either a banjo and locknut or an earthing nut.
The Wiska earthing plate, ec607, is 25mm so wouldn't maintain the ip with a 20s gland.

So what can I do?
It seems i need a long 20s gland or a 25mm gland for that swa.

I'm sure someone has come across this issue before.

Thought about that. But I'd just fitted it and can't be bothered taking it all off. It has 6mm T&E, 2x 4mm flex and 4mm swa. So i went for this one for the size. I'm still learning, obviously, but this might be the only option.
P.s. do you live on here, that was fast

Need outdoor, but my god they look expensive. If rather the faff of changing the box.

i always bin fast. I'm a scouser. you have to be fast to avoid the fuzz when you got a bag full of knock-off gear.

25mm banjo and you are away?

Presuming the m20 to m25 adapter is metal, not plastic!

See what your saying but, the reducer is plastic and even so the reducer sits flush in the box and the gland sits below so nothing to fit a gland and locknut to regardless

It looks like this is the path I'm going to have to take.

So next question then would be.
I know it's best practice to earth the swa armour at both ends, but you can do it at one end.
Can that end be the load end?
Obviously if you had a long swa run it would make the return path far too long, but I'm only using about 7m of swa.
This way I could keep the box on the supply end the same. Large to accommodate the cables and use a small one with 20mm knockouts at the load end.

It has to be earthed at at least one end and preferably the supply end.

Key word preferably.

You could seal the glands with plastic conduit glue.
