Wiring up a new oven.

I'm replacing our single oven with a double, the old one is plugged into a 13amp amp socket.

The new is too powerful to run on a ring so will need it's own connection to the fuseboard.

I know it will need an isolator but will it need a separate fuse?

My limited knowledge of electrics tells be the fuse board is there to protect the wiring and each appliance will have it's own fuse of the correct rating.

As the oven is the only thing connected to the fuse board will can I rely on the board or will it need another fuse? If so should it be before or after the isolator.

The oven can use 4.9kw so the fuse will need to be ~25amp, would a 32a breaker be ok?

If it needs a separate fuse should this go before or after the isolator.

you'll need a connection to the consumer unit. that will need to be connected, via the correct sized cable (6mm will be fine for that size), to one of these:

https://www.screwfix.com/p/mk-2-gang-45a-dp-switch-with-neon-white/15973

or similar, above the worktop somewhere. that then connects (again using 6mm) to one of these:

https://www.screwfix.com/p/mk-45a-cooker-connection-unit-white/16686

under the worktop, which then connects to your cooker, using the cooker cable.

32A breaker will be fine.

all advice to be taken at your own risk, etc etc.

Legally, I think it's something that is now only meant to be sorted by a qualified electrician.

Most houses have a 30A spur with an isolator for the oven. Get an isolator with a socket and you can plug your welder into it (when the oven is off).

Use 6mm sq cable.

I rewired my entire house, including a double oven supply with the assistance of a Collins diy manual and some pdf's I downloaded.
If you've got the motivation, it's easy stuff.

As much as various tradesmen have pissed me off for many of the above reasons and more. You really are just better off paying for it to be done.

Or, if you have not purchased the double oven - AO.com will fit one and send a 'competent' person to do it for an extra fee.

I had entire an new gas central heating installed last week and the plumber wanted to plug the boiler in to one of the kitchen sockets. I insisted we just got an electrician to install a proper spur for it... it's only a few quid and the job is proper.

Oh well, no kittens died.

Yes I was pissing around it would seem, looking at the best rated Trust a Trader and check a trade and leaving messages for each of the top 3/4 in the area was a total waste of time. Where are these magic plumbers you get then? I suppose I will have to endure several more of your smug mocking posts before you dispatch any actual advice as per usual...
