>Comment: The type C 20A breakers Belgian use for the sockets will thus trip between 100-200A. The type B 32A breakers that Paul use for Ring mains will trip between 96-160A. Hence, there is less risk of fire and an appliance "blowing up" when it is connected to a British socket with live and neutral reversed, than when it is connected to a correctly wired Belgian socket.
You are forgetting that those breakers also have a thermal protection and therefore at 40A consumption on a 20A breaker type C will also trip after 25 seconds. A type B breaker 32A will never trip at 40A consumption.
Here is a link to the graphic display of the differences between B and C curves:
