Kitchen Wiring.....

Hi guys,

What size cable and mcb would you need for a oven that says total electric comsumption 2.3kw

thanks

Well, by calculation 1mm² and 10A but you wouldn't.

Do you have a cooker circuit from the CU to the kitchen?

You could plug it in to a normal socket although it is better if it is on a separate circuit.

i sorry for the lack of detail.

The cooker is currently on a 32mcb circuit not sure on the size of the cable.

My kitchen is an old extension of the back of the house so its miles away from the consumer unit.

I was thinking of adding another consumer unit into the kitchen with a source from the main consumer unit so I could add a new circuit for the cooker, a new circuit for the induction hob I intend to get, was also thinking about add the kitchen sockets onto the new consumer unit as ALL the sockets in the house are on one circuit.

Just researching into cable sizes and mcbs...

The oven totals 2.3kw and the induction hob totals 7.2kw

Just need to know what sizes and mcbs for the above circuits and a cable size and mcb to run from the 2nd consumer unit to the main unit...

My brother in law is a sparky, but does not do mates rates and is unhelpful with advice. Was going to get him in before launch day to test it lol

You can wire the oven to the same connector as the hob.

Either wire a socket to the connector and plug in the oven or
wire a Fused Connection Unit with 13A fuse to the connector and hard-wire the oven flex.

could you explain that abit better

so I could simply spur a fused 13amp socket off the cooker switch and plug the oven in to the new 13amp socket and run the hob hard wired into the old cooker circuit??

 

[ant2781]

also what would be the best way of extending the cable??

The current cooker switch is on one side of the kitchen and the new layout if I were to use the cooker switch for the induction hob it would be 3m by 1m away from the current location of the cooker switch.

Yes.

There should be a Cooker Connection Unit behind the cooker.
(If not, run a 6mm² cable from Cooker Switch and fit a CCU.)

Run the hob and oven socket (or FCU) from this CCU.

could I spur a double plug of it as the integrated fridge freezer is next to the oven

The current cooker switch is on one side of the kitchen and the new layout if I were to use the cooker switch for the induction hob it would be 3m by 1m away from the current location of the cooker switch.

The cooker switch should be within 2 metres of the hob for use in an emergency.

No.

 

[ant2781]

I'll have to move the socket nearer lol

so is this the sort of thing we are talking about

found this pic..

ta for your help....started trashing the kitchen

the wire between the ccu and the fsd is that 6mm too?

is the a maximum length allowed between the ccu and the fsd?

 

[EFLImpudence]

the wire between the ccu and the fsd is that 6mm too?

CCU and FCU - 4mm² will do

is the a maximum length allowed between the ccu and the fsd?

CCU and FCU - No.
