Can anyone help me choose the correct junction box to join 6mm t&e to 6mm swa (3 core)... I'm connecting internally before swa leaves building.....



Fair enough I just use the wiska as standard.If it's inside it doesn't need to be weatherproof, would suggest adaptable box.

Have any of yous actually used wiska boxes? The ones I use have m20 threaded entries and you'll not get a piranha nut on the back of that, they offer their own proprietary earthing clamps for use with these (which I'd recommend if you're going that route). You'd also need a gland you can make off and split or you'll end up shagging the box tightening it up. Nothing wrong with drilling through a metal box for banjo and they take more abuse. Also, what do you think "adaptable box KO" stands for?I'd also use a piranha nut to secure the SWA and link the Earths rather than a banjo & strap. A stuffing gland for the T&E
I would also opt for a Wiska as it has knockouts making it very easy to use. A slightly deeper box helps get the SWA fixed too

Yes, if you read my post I stated you need to use a deeper one the 51mm aren't suitable. I'm fully aware what KO stands for the Wiska's are threaded.Have any of yous actually used wiska boxes?
