40 amp fuse

[Angela Robertson]

I am in need of a new built in single oven. The current oven I have is hardwired to the mains with a 40amp fuse at the box. However, the oven I want to replace with BOSCHHBA63R252B requires a 13 amp hardwire, (as are most of the others I have found). Is it just a case of replacing the fuse in the box or would this mean a total rewire from the oven back to the fuse box?

Thanks for any advice in advance.

As it is 13A, it should come with a plug.

If not, as the details do state, then you could fit one and fit a socket instead of the wall connector.

I had paid for it to be installed but the guy this morning said he couldn't fit because it's a 40 amp fuse at the box and the oven needed 13 amp. My solutions were either choose another oven or have the fuse converted. Since almost all the ovens are 13amp, some with and some without plugs. I was trying to work out if I'd be better to change the fuse in the long run, a sort of future proof it.

If they are rewirable fuses,

you could change the fuse to a 15A one - no 13A fuse wire - or just replace the fuse wire in the 40A holder to 15A.

If you do this, it would be advisable to leave a note nearby.




It might be alright just to connect the oven to the existing wall plate but I would advise having an electrician test the circuit to verify this.

If they are rewirable fuses

Weren't rewirables 45A? 40A Suggests MCB to me, I could, and probably am, wrong though. I can probably count on one hand the number of Wylex boards I've seen with anything bigger than a 32A in

 

[EFLImpudence]

There are 40A ones.

Some boards should not have higher than 30A - but it wouldn't matter with an oven.

 

[EFLImpudence]

Actually - now you ask, I may be getting confused with cartridge fuse holders.

 

[EFLImpudence]

So, to Angela - What do you have?

 

[sparkwright]

The 'classic Wylex fuse box' would have cartridge fuses for 40 and 45 amp.

Wouldn't the best solution be to fit a socket onto the end of the cooker circuit?

Assuming the cable is 6mm2 or greater.

Hopefully you have a cable outlet behind the oven, which would be a straight swap for a single socket.

Photos would be helpful, though not essential.

I have a feeling this will be a cooker, not an oven

the cables will be very big and stiff.

Presumably there is an outlet on the wall similar to this

Is there any reason not to put a surface socket box adjacent to it? Wired to the terminals in the cooker outlet block.

Then the cooker outlet is ready for next time an electric hob or cooker is installed.

Your installer was just looking for an excuse to finish his rounds quickly. Argos by any chance?

Its a single oven, not a cooker
The info says

So, @Angela Robertson , the best option is to change the wall outlet to a standard single 13A socket, and connect up a cable with a 13A plug on it.

Other options are available, but will involve work in your fusebox, and you really don't want to do that.

re

The opposite is the case! Many ovens (such as those made for a general European market) are rated at more than 13amp. So a UK plug doesn't work.
Also I see many folk wanting to have a single oven PLUS something like an induction hob. Your wiring, as it stands, would support such a future requirement.

I'm putting my money on Currys...
