Oven connection

Even though the plug fuse is after the 2.5mm cable? The way I imagine this circuit is the 2.5mm cable has nothing before it down-rating the 32a circuit. In other words it is being 'fed' by a 32a MCB.

Circuits aren't 'fed'; the loads 'draw' current.

MCB's aren't self negotiating, are they?

I'll say "No" but am not sure what it means.

So take a simple circuit of MCB > cable > FCU > appliance, even though you might have a 3a Fuse in the FCU, the circuit is delivering 32a up to the FCU? After that it's 3a so can use 1mm cable.

The circuit is not 'delivering' anything.
The current 'drawn' is dependent upon the load and the characteristics of this load mean that various means can be implemented to ensure it is safe.

Not sure if you saw my edit before posting?

I didn't, however...

Thanks guys,
So to summarise, it doesn't need the rcd socket.
Am I right?

You are.

I would think that it was installed because 'newly fitted sockets must be protected by an RCD' but that does not really apply to a socket behind an oven - unless you plug in your lawn mower there.
