Change from Gas to Electric Hob

The size of the MCB required for an induction hob is dependent on the power output of the hob. The power output of an induction hob is measured in kilowatts (kW) and can range from 2kW to 7kW or more, depending on the number of cooking zones and the size of the hob. The MCB, or mini circuit breaker, is designed to protect the electrical circuit from overloading and short circuits. It is important to choose the correct size of MCB to ensure that it can handle the power output of the hob without tripping or causing damage to the circuit. A qualified electrician will be able to determine the correct size of MCB required for your specific induction hob installation. It is important to ensure that the MCB is installed correctly and that the electrical circuit is tested to ensure that it is safe and meets all relevant safety standards Having a double oven already installed on one circui, if you where to spur off this and add another 32A induction hob to this you would be overloading your circuit which will cause the MCBs to trip under a overload condition when you’re cooking using both Oven and Hob

Hello, It depends on the size of the induction hob(Kw rating) really. I would imagine a new circuit will be required as most induction hobs can be 7kw+. Current is worked out as 7Kw or 7000W(your load) divided by 230v(your supply)= 30Amps. I am presuming your double oven is electric and therefore I would recommend that an oven and a hob is too much for the "red switch", as it would exceed the (presumed)32 amp rated breaker your oven is on, if both appliances are being used at the same time. If however your oven is gas then it may well be appropriate and within regulations to add it onto the red switch. Hope that is of some help. Conor

Depending on the size of the power output on your new induction hob. This could be either have a new cable (cable size dependent on power needed) or potentially use existing cable from the double oven. Generally the fuses are only upto 13Amp though (around 3kW). It all depends on the new load power to the hob and also the load & cable of the existing cable. Ideally you would run a new feed into the hob.

It all depends on the current rating of the induction hob as to what size cable, the length of run and how it is run and the existing overcurrent protective device you require, electricians will never agree on anything, but if you have received written quotes from electricians who are part of a competent person scheme who have actually seen the work required you are best gathering information from them, best of luck

All the answers on this topic are trying to reinvent the wheel. It does depend on the rating of the oven, yes, but its not an industrial oven or industrial hob pulling mega watts, its a standard domestic environment. With load diversity there is rarely any need to do any more than a standard 32A circuit with a 45A isolation switch. This arrangement is good for a total load of 15kW. Its been in use for many many years and too many electricians try to reinvent the wheel. Nothing complicated about it, just a 6mm2 T&E cable on a 32A mcb connected to a 45A double pole switch then through an outlet plate or direct to the appliance. Simple.
