4.2kw is almost 18 amps and 2.5 Twin and earth is rated at about 22 amps depending on how it is run/fixed etc. I would be happy to leave it in place with a 20 circuit breaker at the supply. And a 20a DP isolator near the oven. 6 or 10mm cable is reqd for a COOKER, but you obviously have a double oven. Just establish that the cable is not passing through thermal insulation on its route, as this could lead to overheating. If in doubt replace with 4mm , you will never get 6mm into the terminals anyway.
***Sparky, It's an OVEN not a COOKER and 4.2KW,not 8 ***

It will actually run on 230 volts, it was changed when we went to European standard. So 4200 divided by 230 volts gives you a current of 18 amps. if your run from the consumer unit is less than about 6 metres then it should be fed with 6 mm cable by a certificated and qualified electrician. They have to issue you with a certificate now under new legislation. Legally you can't change the cable yourself. But if you were a qualified and certificated electrician it would go straight to the consumer unit on a separate circuit breaker rated at 30 Amps. The cooker must be well earthed and all connections should be good - or there is a fire risk. the electrician may even check different parts of the cooker to see how well they are earthed and adjacent units like the sink or washing machine - even water pipes must be earthed.

Is the oven the only item on this circuit.
It would be perfectly safe to do so, on a radial only feeding the cooker only, on a maximum 20A circuit breaker. If the cooker is on a circuit, feeding other items, or sockets, it would be advisable to upgrade to 6mm. you'll also require an isolation point (cooker switch), not more than 2 metres from the appliance. Being in the kitchen, classed as an increased risk area. i recommend you get a local self certifiable sparkie, to do any work involved, as this will help getting it sorted quicker.

.......No, you should use 6mm twin/earth cable. By the way are you aware that the new regulations prevent you from doing this work yourself unless you are a qualified electrician able to provide a certificate to the local authority. On the other hand, no one knows you have acquired a new cooker. Make sure you use the correct rated MCB.

Do yourself a favour and change the entire circuit over to 6mm twin and earth. If you cook a large meal and draw the full current over 2.5mm cable you may have problems. Check to see that you have at least a 40amp breaker at the fuseboard. Also check that some ******** hasn't spurred it off of one of your ring mains!

No - it should have it's own separate supply rail rated at 30 - 45 Amps, cable size 6mm. If in doubt, consult a qualified electrician.

Quick answer....NO . Regulations specify 6.0 m.m.cooker cable, in fact there are French ovens that require 10.0m.m. cable

I have the old easy bake oven that me and my sisters had as kids. I was thinking of busting it out and baking a cake. Wanna join me? Maybe you can provide the milk that the recipe so desperately needs.

watts divided by volts equals amps so 4200 w divided 240 v equals 17.5 amps 2.5mm is good for about 15 amps so no unless you want to start a fire be safe go for about 6mm
