advice for fitting new electric oven

[steunited]

Hi all we are looking at replacing our 14 year old zanussi single oven which is only 2.15 kw.
Some of the ovens we have looked at are rated over 3kw so need to be 16amp.
Is it possible to tell if our wiring will be able to cope with an oven over 3kw just by looking when i pull the old oven out.
Also what work would be required to enable a 3kw oven to be fitted.
thanks

1. is the new oven fitted with a plug top?
2. how is the existing oven connected? is it hard wired from a 45A switch?

a pic would help.

Is there a hob on the same circuit or just oven? more than likely it is wired with a minimum of 6.0mm cable. As Tel said post a picture of the oven outlet and consumer unit.

haven't actually chosen an oven yet till we determine whether we can only have 13amp one or 16 amp and i haven't pulled the old oven out as yet to see what connection is behind it.
i will have a proper look tomorrow and get a photo
just thought i would ask beforehand
thanks

As above mate. If you post a pic of the CU then that will give us a good idea of what you have. Or see of you have a 'cooker' breaker and tell us the size.

Have just switched both oven and hob on and flicked the cooker switch on the wall off and both went off so must be on same circuit

what make of single oven are you going for!

if we have to go for 13 amp it will probably be a Bosch but if we can get away with 16 amp we were looking at AEG

^^ that would suggest you have a dedicated circuit that is supplying the cooker and hob .............. what type of hob do you have?

 

[buzzlightyear]

Zanussi!

 

[telectrix]

what he said^^^^^.if you have a dedicated cooker isolator like this:

with or without a socket outlet, on a 32A MCB ( as labelled in your pic of the CU), you're good to go up to 15kW hob and oven combined. the actual connections will be behind or to one side of the oven via a cooker connection unit. like so:

 

[buzzlightyear]

BOSH no plug wire in.
AEG no plug wire in .

It's a Zanussi same as the oven and was fitted new when the house was built in 2003 but don't really know if it's ceramic,halogen etc

[buzzlightyear]

ceramic,halogen etc

ceramic is the glass ,halogen heat,

as i thought. you should have no problems there.

what a clean kitchen, hot milk for the coco drink then !

Thanks that's good news i didn't want to order a higher rated one and find out it couldn't be fitted when it got delivered but also didn't want to order the lower kw one only to be told i could have had the higher rated one after all.
Will i be able to wire it in myself or would it be wise to get pay the extra £90 for fitting(eek)

 

[buzzlightyear]

most ovens are A rated ,by the SS of EU directive .

 

[Toneyz]

At a well-educated guess, you should have a minimum cable of 6.0mm
once you take the old oven out you should be able to post a picture of outlets behind as there are several different ways the existing could be done.

most electricians would charge around £50 -£55 for that. it's only an hour's work including a quick test to prove the circuit healthy. for DIY you just isolate ( preferably at the consumer unit) and use the existing cables by dissing at the oven and hob themselves and just connecting into the new appliance/s. however, some of these newer appliances are a bitch to connect the terminals, so for the sake of the £50 i'd get a professional in. ( but don't let some muppet try and talk you int rewiring with 10mm cable, as some of the newer generation of sparks would advise).

Agree, had a job just like that before xmas, new cooker and hob, the cooker had the most frustrating termination block on the back, it had a screw, 2 push in clips and another clip that needed to be pushed in and lifted at same time whilst pushing the top as the plastic had flexed and moved at some point. It made it a nightmare. once done you could then reach the prize of 3 screw terminals!

I know quite a few sparky's so will see if one of them will do it

well just ordered this one from very and and also had a 10% off code to use so with delivery it came to £457 and AO.COM are selling it for £549.
Decided to go for one slightly under 3kw

thanks for all the advice i received

 

[telectrix]

don't bin the old one. if you want to get rid and do some good at same time, contact age concern.

to be honest not sure they would want it as the fan sometimes takes a couple of minutes to come on and it's pretty horrible inside

Look, check the side of the Oven, there is an information there, you will see the voltage Ratings and the wattage. You have to use the Amps on the Oven to select the circuit breaker

Think he'll have fitted it and cooked several dinners with it by now
