Any electricians in the house

Just started pulling our old kitchen to bits for a new one.

We have an electric fan assisted oven at the moment and a gas 4 burner hob.

Her in doors wants an induction hob. Me = gas but I don't get a say in it lol.

Question is can the new hob be wired into the existing main that feeds the oven, think its 30 amps all to itself. ?

you'll need to check the circuit & breaker feeding the oven first to make sure they are up to doing both the oven and the hob. All four rings on a hob can draw quite a bit of current.

Assuming that is OK you could take a feed from the oven isolator to the hob, but you may need to change the isolator depending on the type.


If you are unsure how to proceed though it might be better to get someone in to do it for you.

Cheers Stu, think it might be best I get someone to have look. Think the rcd is a separate switch for the oven though

30a for an oven. Blimey! That would be okay for a hob and oven together as even if you had all four rings on they're not on full all the time so by the rules of diversity you can get away with lower ampage. As long as the mcb is rated below the cable the worst that could happen if someone did try and burn your house down by switching all the hobs on full is that the mcb would go.....

A lot of the modern induction bobs will draw big current.
You need to check ;
Cable size
Mcb size
Max oven load (whether grill can be used at same time as oven)
Induction hob load
Then report back!

I thought induction hobs were meant to be very efficient? So one would presume the current draw wouldn't be too mad? Not challenging anyone just interested to learn.

Mrs Joe may need all new pans too mate so don't forget to factor the cost in. For me, it's cooking on gas all the way.

Cheers

As said you need to check current draw on new hob and oven, also check cable size, depends on the hob but most power share so can be run off of a 2.5 mm supply.

With diversity you can put 15kw on a 30a 6mm supply. As said, it doesn't all get drawn at once, and if it did then it's only a tripped fuse to worry about.

One important input is that some new induction jobs, Siemens for instance, can be programmed to not exceed a certain current draw - even functioning on 13a at the extreme. Most times you won't even notice the difference.

Definately do not pair up on a 2.5mm. It will only carry circa 20amps

Lee. Gas for me. Electric for mrs. I cook mostly but. She wants looks. Tried gas on glass but she's not for having it

I need to get some one round I think to double check
