We have ring circuits, which are typically on 32A breakers.

3000 W / 230 V = ~13A, does this mean I could run two 3kW kettles and still have 1.3kW spare before everything shuts down?

That's massive.

And it's great, until the ring is broken. If a ring becomes disconnected, you then have a single 4mm circuit rated at 18A carrying 30A.
