Induction hob + double oven in new kitchen

[xr4x4]

hi all again,

as i didnt get my answer in my last post involving this, im trying a different tact.

doing a kitchen refit for customer, they want a induction hob to replace gas hob and a double oven to replace single oven.

will be starting monday and have already assessed the power and only have a 6mm cable on a 32mcb, which fed old single oven.

customer wants us to look into cost to run new cables etc.

now i know i will have to call in a electrician as its not my company and its not my neck on the line and it looks like we might have to get the fuse box updated now anyway.

for my own piece of mind and being to type of person that likes to know how things work, id like to know how it needs to go about being done.

new double oven will be 20 to 32amp, induction hob 32amp. no spare ports on fuse box.

what do we need to get a quote for?

thanks.

Simplest answer really is get your electrician in to survey the job and he will provide your quote.

What is the WATTAGE of Each Appliance?
How long roughly is each cable run?

As for changing the CU, this will depend on a range of items, you could however fit a second board for these new cicuits, again a survey of the job is required.

doesnt mean that he will be correct tho does it, id like to know at the time if its right.

oven 7400watts, hob the same.

about 5meters on the cable, each.

What do the manufactures instructions recommend?
That will normally take president.

as said 32amp and 30amp.

.

But you said the oven was 20amps = 4600 watts??

I dont believe the 7400 watts figure for the oven. Can we start again with the correct info?

Which post was that?

for my own piece of mind and being to type of person that likes to know how things work, id like to know how it needs to go about being done.

1) Ensure your piece (sic) of mind by getting a competent electrician to do the electrical work.
2) Learn how it's done by watching him.

what do we need to get a quote for?

Who is project managing all this?

 

[1john]

You need quotes for the following -

1 - Periodic inspection report (to asses the existing installation against compliance and condition)

2 - Some sort of hourly rate / quote for any required remedial works raised from the PIR (he needs to do the PIR first for this)

3 - Quote for installation of the consumer unit (if not already covered by #2)

4 - Quote for circuit design and installation for the additional loads in the kitchen

Also, you said that you are

doing a kitchen refit for customer

Is the electrical work limited to the induction hob and oven or is there other (lighting, sockets etc).

If so all the work will need to be done to the new regs and will require RCD protection.
This may need a change of the consumer unit, or substantial updates to it.
That can only be determined by a site survey and a view of the plans.

the oven hasnt been choosen yet, will be 20 or 32 amp, which one we choose might depend on our wiring limitations. so it seems obvious to run/have a 32amp radial for both oven and hob, as i dont think one 10mm cable will cut it, let alone how big the mcb will have to be.

there will only need to be one new curcuit run, all the other wiring fcus and sockets are all in place, they might just have to be moved a bit.

im not sure if the cu has rcd protection, the cupboard is full of ****e, although i can reach it, i cant read the info on the main switch. it has a test button on the main switch which cuts everthing off.. is that a rcd?

 

[Taylortwocities]

Yes, but the main switch should not be an RCD - unless you have a TT installation. So that will need sorting out.

needs a photo of the board and of the incoming mains head to determine.

Nad as I said above

That can only be determined by a site survey

You cant determine this sort of thing on a DIY forum. You need a registered electrician on site to give you a design, pricing and to do the work.

The new induction type hobs can draw far more than 32A so if you are fitting a new supply then you should be looking at a 45A supply to allow the use of larger hobs in the future.

The 'other thread' is here:

However this:

doing a kitchen refit for customer

will be starting monday

is outrageous. You are supposedly installing this kitchen for a customer in less than 24 hours time, yet you apparently have no provision for electrical work at all, including not even knowing what type of consumer unit or fusebox this property has.

there will only need to be one new curcuit run, all the other wiring fcus and sockets are all in place, they might just have to be moved a bit.

All notifiable work, so if you start doing any of this, you will be breaking the law, and putting your customer and their home at risk of injury, fire or worse, since it is obvious that you don't have any of the required knowledge or experience to be undertaking electrical work.
