SWA/wiska box/piranha nuts

[pirate]

Some assistance please.
simple job really, 3-core 4mm SWA to be glanded into a box with a 20mm S gland, and piranha nut.
I'm not familiar with the Wiska brand, but as it gets a good name I thought I'd try a couple. Was looking at the 206, but frankly I get easily confused so maybe one of you might suggest the best box.
Thank you.

I think the whisker boxes are pre threaded to 20mm thus been plastic are not really suitable for swa earthing, the piranha nut simply will not fit, I would get a standard IP rated plastic box and gland as normal using the earth ring or piranha nut as required.

You can use the wiska gland plates

Aren't they threaded 20mm entries, P. Have a job on with the earth locking nut. Get the metal plate arrangement for internal earth linking.

Valuable information, gentlemen...thank you.
So the gland plates are Wiska's version of Piranha?

Wiska Earth Clamp Bar for SWA Glands for WK407 | Wiska (10105647)

I was keen to try the Wiska brand, so maybe I'll go with their gland plates.

Or go with Darkwood's suggestion, which clearly will work fine with Piranhas

Another vote for the earth clamp bar ?

 

[Darkwood]

Well I honestly hadn't come across these mainly because I don't tend to need things like this but good call.

I have some Piranhas though...
maybe just go with a plain box, and try the Wiska range another time.
so many plain IP rated boxes to choose from, so that's maybe my easiest solution.
I thank you all for your input...much appreciated, and gratefully received.

I personally have not tried a piranha nut thingy , I usually just put the bangos on the inside kink them up and bolt together,,,,

Yer missin' out, mate. I wouldn't be seen without them, these days.
Just installed some pvc 32A 3 phase/N/E 5 pin sockets with isolators. They leave drilling and linking banjos in the shade.
Do they go bang. by the way?

 

[Darkwood]

Piranhas are a good choice for compact stuff like isolators where a banjo simply is too big and sticks out past the edges of the box.

An earthing nut will not fit those boxes stick with the proprietary Wiska earthing plate.

And let's not forgot on wiska boxes are self-drilling - no need to pole out the knockout, just screw your gland into it and it'll do the knocking out for you .
