New Cooker

[Steve 34]

Hello all,
I just bought a new Indesit cooker (built under) and I am uncertain how to wire it in the cooker is rated at 5.2KW it has a double oven and grill. The instructions show wiring it with the hob but I have a gas hob which is wired seperately, so I need to wire it on its own. I have a spare trip on my CU which was used for an old cooker (rated 40 amp not used fo 5 years) I would like to use this as the old oven used to trip the 15amp breaker on the old ring when using too many appliances. The instruction show a double pole switch and 4mm cable is this correct as I cant find 4mm cable only 6mm or 10mm also what size breaker do I need (the unit is a Wylex NN )

I'm not a sparky, so don't take this as gospel.

If you have an old cooker circuit which has a 40amp breaker in the CU, this should be fine to use, although you will need to change the breaker to a lower rating to match the cooker. If it was a cooker outlet before, it should also have a double pole switch in place.
Because this work is in a Kitchen and you will be changing the "Circuit Protective Measure" this will be covered by Part P. Easiest by far is to get a sparky in to change the breaker and wire the Oven in for you.

Hello,
I have just spent an hour going through old posts (which I should have done first) I am I right in assuming that I should do the following:

Use the 40 amp trip in my CU (but change to 32amp)
Use a 45 amp double pole switch located less than 1 meter from the oven
Use 6mm2 cable

Does this work require a quailifed electrician

regards Steve

Yes

Yes

Use 6mm2 cable

Yes

Does this work require a quailifed electrician

Yes
As mentioned in my previous post, any change to "Circuit Protective Device" i.e MCB etc is Part P and will require a Part P registered electrician.

No. You can do this work yourself under a Building Notice to your LABC, together with the appropriate fee. They should then inspect/test and issue completion certificate.

However, it's probably going to be cheaper and much less hassle to use an electrician who is a member of a part P competent persons scheme (which is not quite the same as being a qualified electrician).
