Wagos for oven

[Steviecuk]

Hi all. Hope you are well.

So my dad has just bought a new induction oven. He already has an electric oven under it which appears that it is hardwired from 6mm T&E that literally just comes out of the wall

the new induction hob has 5 wires (which obviously has doubled up lives and neutrals) but along with the oven as well it would be much easier in a confined space to connect in a junction box with Wagos.

I was thinking the Wago 41A junction box and the Wago 211 41A 4 or 5 way lever connectors. The box would then be mounted on the wall.

Does this conform to regs a) using Wagos and b) with the built in Wago strain relief clips.

I just know trying to jam 4 wires into a traditional outlet box won't be easy in a tight space.

Look forward to hearing back from you.

if you use the 6mm2 version of the wagos and its in a MF box ,suitably located ,it should be ok.
The only concern is the protective device ,protecting the flex cable,this is no different to a flex outlet

ok so something else has now come up in working this out... the oven is rated at 15a and the hob at 30a. The MCB it's connected to is only 32a. The fuse board has the old Centaur Type 1 M4.5's.

I know the oven won't be at full tilt along with all 5 induction rings on max at the same but will this work with the current setup or keep tripping? If so is it possible to get a newer 40a MCB fitted in its place?

I believe the 6mm and 40A MCB debate is a little contentious at times.
It depends on the installation method, being pretty close to the tabulated max current for 6mm you can't be de-rating it much at all.

It's worth looking at the data sheet for the hob. Some pull close to their max on only 2 rings, for this reason I tend not to run with diversity too much with induction hobs. If possible I'd run a 2.5 or 4mm radial from the board with a 16A rcbo and have the cooker on a separate supply, appreciate that's not necessarily an appealing option though.

Also, and I'm very happy to be told otherwise, I'd probably consider the connection to be accessible, so probably wouldn't worry so much about the de-rating of wagos you're meant to apply in MF applications.
