Cooker becomes Oven and Microwave....any ideas?

[timhoward]

I'm interested what people's gut reaction solution would be.

Kitchen design and customer said freestanding cooker. So I first fix 10mm, and boxes for cooker switch with socket, and cooker connection plate.
No one thought to tell me it became hob (elsewhere, that bit isn't a problem), and a vertical cupboard which will contain an Ikea Microwave combi thing (<13A which came with plug) and an Ikea oven (3.490 Kw so 15A max which came with bare wires). Instructions for oven do not specify an overcurrent device..

One has fan, one has motor, I can't really claim they are fixed resistive loads, chop plugs off and connect them!
I also don't really want to be even thinking about putting a socket on 10 sq mm cable.

Any creative ideas? (It would be really handy to know if the fan was fused internally in the oven....)
I can only think of tiny consumer unit at the moment. Any help welcome!

This situation within kitchens I think has never been successfully discussed with a sound solution., leaving the installation of a dual cooker plate & everything connected to it regardless of individual appliance circuit protection.

This is a joke, don't take me seriously anyone, but an MK grid plate with a 13A and 5A fuse in parallel briefly came to mind!

Okay, fed from a dual cooker plate, isolated from Cooker Main switch? I take it this will be behind where the free-standing cooker was to be?

Cooker isolator faceplate is in a corner cupboard / walk in pantry.
Cooker plate (currently single but can swap) is behind an adjacent fitted cupboard unit which is where microwave and oven will slide in.
Plenty of access to plate luckily.

(I wasn't serious about paralleling fuses)

Why not it is a solution to overcome a problem

Connect the oven to the dual plate & MK fuse for the microwave socket outlet. Parallel fuses is better, seriously.

What is wrong with paralleling fuses and how is it different to paralleling MCB's when we install a CU

I'd put a single socket next to the cooker outlet, spurred from the terminals of the outlet in 2.5mm, for the microwave. The oven I would wire directly into the outlet.

I see your concern about overcurrent protection for the fan part of the oven, should it stall, but I can't see a 16A MCB providing that protection, bearing in mind most domestic extractors say either max 3A fuse or max 6A MCB.

I would assume this protection is provided by the oven itself.

I don't think either of you realised I fleetingly entertained joining both ends of both fuses together to construct a 20 ish amp fuse...
(We don't connect a load to more than one MCB at once.)

Anyway, the microwave isn't really a problem, I could put a short length of 6mm from a dual plate into a single socket or FCU.
It's more the oven bothering me as an appliance that generally draws 15a max is on a 32 or 40amp breaker.

Thanks. It's a good point that even fusing it down won't actually help the perceived problem.
