another 'replacing hob' thread

[PrinceofDarkness]

Well, let's discuss it now, shall we Echoes?

Small ovens are often supplied with a 13A plug or MFI's instructing the use of a 16 or 20A circuit. This is because the manufacturer has no idea whether his oven will be 'standalone' or used with a hob.

Ovens, hobs and freestanding cookers are notoriously impossible to protect with a single device. This is why we select the protection solely for the fixed wiring of the circuit.

Take the case of a freestanding cooker (or oven): The protection would have to handle a fault on any one - or all elements including oven, grille etc. It would also be required to handle a single fault to the oven timer or the oven light even.

Since none of those individual components are fused separately, and since none of them can be overloaded, then the main consideration is short-circuit protection for each and all of them and therefore for the appliance overall.

Merely pointing out that despite all that, all of which I agree with, the manufacturer's instructions often specify that a 13A fuse is 'needed'.

You seem to be anticipating an argument: "Well, let's discuss it now, shall we Echoes". You won't get one. Since you have articulated the issue, would you recommend the OP uses one or not, box-tickingly unnecessary though it may be?

Thank you, Echoes, no I'm not looking for an arguement.

This hob and oven combined can be regarded as a single appliance with no other protection but that of the fixed wiring protection.

A bit of activity overnight then... Thanks again for asking the further question and then also answering it too
