20s gland into wiska reducer problem

[Dan Carroll]

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.

or replace wiska box with one with 20mm entrys.

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

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

Cant you just use an unbranded adaptable box?

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.

Should’ve used a galv reducer probably

You could seal the glands with plastic conduit glue.

Was wrong footed by the same problem last week which left me scratching my head. As James suggests, I ended up fitting a banjo on the outside sandwiched between the SWA gland and reducer. Not perfect but got me out of a hole. Moral of story, check materials before heading on site!

Use a metal reducer instead of plastic and use an earthing nut.

Or put a long nipple through the reducer you've got, fit an earthing nut on the inside and a coupler on tbe outside to run the gland in to.

Or use a nipple to fit a galvanised through box to the wiska box and fit the SWA gland to that.

Use a long whisk gland kit.
