Fitted Kitchen.

Devonian_Rodders

My son had a new kitchen fitted, complete with electric oven & hob, by a DIY chain just over 3 years ago.
During the warranty period there were issues with the oven, which were fixed. However after the warrantry period the oven continued to give problems on a regular basis, necessitating visits from a manufacturer approved service engineer at £70 plus parts per visit.
Being somewhat frustrated at the inconvenience of having to make himself available on a specified day, he decided to purchae a new oven from elsewhere, in an attempt to eiliminate the issues, since neither supplier OR manufacturer were concerned.
When the new oven was delivered, the retailer declined to fit it since the original had been fitted incorrectly. This was because the original should have been wired into the circuit, rather than havee a 13A plug fitted which was lethal !
Although there may be no chance of proving the Kitchen installer incorrectly fitted the oven, this might serve as a warning that package deals from D I Y chains are not always good value.

A lot of electric ovens(but not all) only need a 13amp plug they don't need a dedicated circuit. Check the current/wattage sticker there's usually one on the oven somewhere.

It could be that the new requires a dedicated cooker circuit while the old one didn't and the fitters are just getting confused.

Hobs usually are the bit that need there own dedicated circuit.

If not then follow the usually routes complain to the company.

Most modern ovens DO need a dedicated supply (16A or 20A).

Incorrect.

Most single cavity built under ovens operate at under 3kw and therefore do not need a dedicated supply. They can be plugged in on a standard 13amp 3 pin plug or wired into a 13amp fsu. A dedicated circuit us not required.

We have been looking into a new kitchen and therefore a number of appliances and we have been told that our induction hob will need to be wired in properly as it uses a heavy load, BUT for 2 single oven they will be connected via plugs it is only double ovens or slide in ones that need the heavy duty cabling where the draw would be high.

phill99 - Apart from 1 entry level model from BSH, everything is 16A. Everything from Electrolux (Zanussi/AEG/Electrolux) group apart from some entry level models is 16A. Everything from Miele is 16A+.

I am talking about single ovens only.

I think that alone covers well over 50% of the built in oven market.

Regardless, this does not address OP's concern.

A 16A oven wired into a 13A supply isn't lethal as long as its been fused. Its definitely poor workmanship.

Well to be honest I am now mightly confused with the advice I have received and then Ryder72's comments. Who are we supposed to believe then when our kitchen is fitted in a few months time???

I presume your son's work would have been completed with a Part P sign off by an electrician, your son should have his details as you need the form when you sell the house plus it is lodged with the council could he contact the electrician to clarify the situation?

The oven will come with fitting instructions provided by the manufacturer. If it isn't fitted in accordance with them it may well invalidate any warranty. So believe them.

Just to be clarify - a 16A oven should be wired into a 16A supply for best operation but connecting it to a 13A supply with a fuse while not recommended it will not be major problem.

Thanks Devonian Rodder for highlighting this.

Our induction hob will use the old oven dedicated point - changed accordingly and we are having a new ring main put in for the 2 new ovens and sockets.

Your post means I will make sure that they are fitted in accordance with manufacturers guidelines as Direct Debacle says and not assume the kitchen fitters know what they are doing. To be honest I don't know much about electrics, so assume the experts do, everything else I have paid particular attention to.
