New electric oven and induction Hob

[Ant62]

We have decided to change the oven and hob for new ones.
we currently have 6mm from the consumer unit running to a junction box the current fuse on the consumer unit is 30amp.

The length of the 6mm cable from the junction box to a double wiring point is 5m..
The wire from the consumer unit is about 6m long...

The intended oven is 3200watt.
The induction hob is 2.3 - 3.2kw..


Do i need to replace the 30amp to 45amp...

No.

No.

I concur, my cooker is rated 47.5 to 52 amp to save you working it out, was on a 32 amp MCB now a 32 amp RCBO and it has never tripped, the induction is more energy efficient to a resistive so although it may peak more, the average use is a lot less.

So do i leave the 32amp in or replace it

You leave it.

Why did you ask the question in the first place?

The intended oven is 3200watt.
The induction hob is 2.3 - 3.2kw..

That is only a total of 27A.

That is only a total of 27A.

Thanks for letting me know....

3.2kW is very small for a hob; are you sure about that.

Whatever it is you still leave the 32A in place.

Hob​

Burner Power Range
2.3 to 3.2 KW......

The circuit breaker is there to protect the cable.

If the circuit breaker is changed to a higher value unit, the cable would fail before the circuit breaker trips - which is BAD

Burner Power Range
2.3 to 3.2 KW......

That means the rings are 2.3 to 3.2.

So if there are four then they might be 2.3, 2.6, 2.9 and 3.2kW.


It doesn't matter, whatever the hob is it and the oven will be fine on the existing circuit.

The circuit breaker is there to protect the cable.

In a way yes, but with installed appliances, it can also be required to protect the appliance, the idea that the fuse is to protect the cable only is only true with 13 amp plugs, and portable appliances, with a fixed appliance it can also protect the appliance.

No, the manufacturer should do that where necessary - and does.

the idea that the fuse is to protect the cable only is only true with 13 amp plugs, and portable appliances,

Perfectly illustrated counter to your own argument.

Portable appliances with flexible leads have different rules.

with a fixed appliance it can also protect the appliance.

Well it also can but that is not its purpose.
