Had a new electric oven delivered today from Ikea, the (picture) instructions show a man fitting a plug to it and just plugging it into a wall socket, it a simple as that. The wife wants to get an electrican in to do it, I don't want to pay someone £50 just to plug the damm thing in
Surely the instructions are more detailed than that?
There are very strict regulations about the supply of electrical goods in the UK. If they are designed to be plugged into an ordinary electrical outlet (3 square pin , usually called '13 amp'), then they must be pre-fitted with an appropriate plug and fuse.
What kind of oven is it? What model? If it's a typical built-in or free-standing cooker oven, with or without hob, then it is almost certainly rated at well over 13 amps, and you must wire it into a higher-rated circuit with its own on-off Cooker switch. In that case, it will have been supplied without a plug, and the cable will be very heavy duty; much more so than say the lead from an electric kettle. You will need an electrician to do that. What do you have already?
If you mean simply a work-top oven (microwave or similar), then you can plug it into an ordinary socket, but, as I say, it should have been supplied with a pre-fitted plug.
What do the instructions say about power rating (watts or amps)?
