3 cookers

[EFLImpudence]

13800 / 240 = 57.5A (a bit less at 230V)

47.5 x 0.3 = 14.25 + 10 + 5 = 29.25A (is there a socket on the switch?)

Second part of my question, the smaller oven (built in microwave combi) spec states "Required Fuse (A): 16" How do achieve this on a cooker circuit? it has a cord but needs hard wiring.

This is the source of a fair few arguments.

Some would just ignore this, BS7671 requires manufacturers instructions to be taken into consideration, it doesn't require them to be precisely followed. Personally I think it is foolhardy to fit a protective device rated significantly higher than what the manufacturer specified but others may disagree with me.

Some would run a seperate 16A circuit.

Some would stick a MCB in a suitable enclosure.

Devil's advocate:

Yes frequently.

They would.

Some would run a seperate 16A circuit.

As in Europe where it is made. Could that be the reason for the stated requirement?

Some would stick a MCB in a suitable enclosure.

That would also not be following the instructions, would it?



Why does it have to be hard-wired?

Why does a 12.5A appliance need a 16A fuse.

What about fitting a larger flex? It can't be rocket surgery, can it?

Well the maker (AEG) manuals state that has to be done by their Service Centre staff

If you can’t get the microwave on the cooker circuit. You could always fit a b16 mcb in an isolator enclosure
And hook it Upto the socket ring.

Be nice to isolate the Neutral too.
One of then double width devices ?

But the MIs state it must be a fuse.

So it depends which MIs you are happy to ignore because you have worked out what is really necessary.

If you insist on a taking the word fuse literally then fuseholders are availble in the same form factor as MCBs.

 

[AndyPRK]

Do they even do 16a fuses in Europe?

I’m sure an Aeg engineer would be happy with a 16 mcb.

I know there help desk can be a little silly at times.

Hager certainly list 16A fuses and fuse carriers to put them in on both their UK and french sites.

Yes, I know. I am just playing Devil's advocate (being awkward) to point out that whilst people are saying the MIs must be followed (even if overload protection might not be needed) there are other MIs that they happily ignore.
