No

their appliances always blow the circuit (eg downstairs ring main)
What ring main? Everything is wired as (chained) radials. But yes,
the only fuse is in the consumer unit.

Are ring mains mainly a UK innovation, then? I hadn't realised that.

Yes, I believe it was basically a copper saving idea in the post 2nd
war years.

Personally I think the disadvantages outweigh the advantages, I always
install 20 amp MCB radial circuits in preference to ring circuits.
