Replacing Old Oven

[Bobbya82]

Hi,

My Oven has given up and finally died, everytime you turn it on it trips the consumer unit.

I am looking at replacing it with this type of oven which comes with a plug attached,
https://ao.com/product/hhf113br0b-bosch-serie-2-electric-single-oven-stainless-steel-61057-45.aspx

The current cable going to the oven is a really thick one, guessing 6 or higher maybe 10mm? which connects into a socket above the worktop (this socket also has a plug socket on it which i have my microwave plugged into) and then the thick cable goes back to the consumer unit into a 32amp fuse labelled just for the oven.

My question is, will the size of the cable be a problem, I was just going to remove the hardwired cable going into the old oven and wire it into a socket, I can then just plug the new oven into this new socket

Will this be ok given the size of the cable, I cant recall how it works in terms of size of cables and amped fuses, when the cable would burn before it trips etc.

I have attached some photos which will hopefully help show the current setup.

Many thanks for your help.

Having a cable that's thicker than what you need isn't a problem. Using one that's thinner would be !

Great thanks, so the socket plan will be fine?. Anything else I need to consider/ be mindful of?

Thanks again

The circuit should be RCD protected. Fitting socket directly behind the oven may impede the oven from going far enough back to the wall.
Turn off power and prove circuit is dead before fitting the socket ,to state the obvious .

your picture appears to show cables going into the wall with no protective cover. This is wrong. Additionally, there appears to be a bare metal thing (perhaps studwork or lathing?) adjacent to or touching the wires. This is very worrying since they could conceivable become live if a wire comes loose.

If there is a square metal box in the wall, that the wires come out of, there probably is an incomplete Cooker Cable Outlet in it. If not, please add one. The connector block inside is sized to take those big cables; there is a clamp to prevent them pulling out, and a plastic protective cover. Crabtree is a good make.

the components inside will be something like

due to the size of the cables, they need a deeper backbox than usual. If yours is not deep enough, you can get a plastic surface one. 44mm deep should do.

thanks for the feedback, really appreciate it.

will put the socket below the oven in the cabinet underneath.

The bare metal thing is part of the oven I believe where the cables go into in.

Am i ok using just a normal socket then like https://www.screwfix.com/p/crabtree-capital-13a-1-gang-dp-switched-plug-socket-white/57089 with a surface back box, I assume the cables should fit ok? and that I dont need something like this https://www.screwfix.com/p/schneide...h-13a-dp-switched-socket-white-with-led/8103j

Thanks again

Yes to the single socket ,you don't need the led one. But the surface mounting box needs to be deep ,the thick cable is a bit awkward to work with.

Cheers guys

No it is not. Twin and earth cables can be plastered directly into the wall. A cover is nice but not required by the regs.

Wall or oven, don't look right to me either

with no sheath on them, and no enclosure?

Nope.

Also, I see now it is laminated chipboard, probably the oven tower, and not the wall (thanks rocky)
