Wiska connection query

[Sadruddin]

I'm a self builder in the very very late stages of a build in which I'm doing the electrics and having them signed off by a Napit inspector.

So. I had a Greenbrook connector connecting shower to mains, (both 6mm cables)

My electrician says I should use Wiska connectors. I've bought a Wiska 110x110 but the connectors aren't really big enough for 2x6mm to go in them.

I can't see a connector replacement to go inside the Wiska.

1) Is there one?
2) If not, is the a replacement for the whole Wiska which either has big enough holes for both cables, or connectors like the Greenbrook which will connect the two cables into 2 holes.

WISKA? Are you sure that he/she didn't say WAGO?

Some, not all, Wagos can take 6mm² conductors. But do check out how many amps your shower pulls. Some Wagos are only rated up to 20amp, some can handle 32amp, not sure about anything bigger - which today's showers tend to be.

I recall buying a wiska box with 6 terminals to join some 6mm cables.
Never got round to using it, but it looked upto the task

They still do, but the smaller 110x110 size boxes do not accomodate joining 6mm cables.
The 57amp 1010 has larger termination capability.

But why go for Wiska? Is the junction outside?

If not, then this is a better way, assuming it will be accessible.

What have I missed? A new shower feed doesnt need a junction box at all.
