Help me connect my oven

[Piemaster]

Forgive me I am a real DIY newbie, so I may be asking stupid questions here.

We have just bought a new house and are in the process of moving in. In our previous house we purchased an oven and in the kitchen there was a large grey cable that we managed to connect up to the oven with no problems and it has worked quite happily for 6 years. However in the new house there is a switch on the wall for the oven (one of the red on/off ones) but there is no cable to connect to the oven. I assume that I need some kind of cable to connect the oven to this oven on/off switch, but I have no idea what I need to buy.

Can anybody point me in the right direction as to what we need to buy?

Thanks in advance

You need to check the rating of the oven (there will a plate somewhere).
You need to find if the supply for the cooker circuit can handle the oven capacity.
If you dont know what you are doing it may be worth getting a sparks to do it.
It should be a simple job & not cost that much.
Make a few tele calls.

Could there be a connector plate somewhere - behind a unit - where a cooker used to be?

First check inside the the CCU (cooker control unit/red switch).
There may well be a load cable that is either connected to an outlet plate or a socket-outlet, this could be behind the oven/oven housing or placed within an adjacent kitchen unit. Isolate circuit or the complete system prior to doing this.
If not you will need to consider a number of things:
The size of the existing supply cable and the fuse rating of the supply, as this will determine the size of oven you can have.
Then you will need to find out what the output of the oven you have is, to see if this is a straight forward connection.
Would say that the size of the load cable should be no bigger than that on the supply side.
But we need values, sizes, ratings and measurements of output of oven, cable size, distance the cable is run and fuse/MCB rating.

Thanks for all the help so far.

I can't find anywhere on the oven where it says the rating of the oven. I looked everywhere, so either it isn't on there or it has come off in the last 6 years at some point. In the house move we have managed to mislay the manual and I am trying to find one online (it is a Leisure Roma 50) but I can't find it anywhere.

I also can't find any kind of load cable anywhere. There is a big gap where the oven used to be (when we viewed the house I recall the previous owner having a large Range cooker) but no loose cables anywhere (although I will have another thorough look when we get back).

I had slightly better luck with the fuse box, which revealed the oven to be a 30 Amp circuit.

Time to call a Sparky?

If it's a free-standing cooker with electric hob you will usually need the 30A supply with 6mm² cable.

This is probably what you have to the cooker switch but it would be best to get an electrician to be sure.

It's definitely a free-standing cooker with an electric hob. I guess I'll contact an electrician, thanks.

Have you opened the door of the cooker, sometimes the rating can be found around the door opening.
Normally you would not expect a domestic cooker to exceed 15kW, which in most cases would be fine on a 30A fuse and 4.00mm cable.
You could call the manufacturers up and ask about the rating, as I have done a quick search and the manual is not available on-line.

 

[Diyisfun]

It is a legal requirement for a rating plate to be fitted. As said it could be on the front of the oven or grill behind the door but fixed to the frame, it could also be fitted on the bottom plinth, get on your knees.

get on your knees.

A bit forward for a newbie on their first thread

Put them in there place at the start..

Thanks for the help everyone. I ended up calling an electrician, who discovered that the output cable from the cooker switch had been completely removed. He moved the box to a better place and then installed a new cable so everything is now working.
