On the other hand, why have laptop manufacturers started supplying their
fully isolated PSUs with 3-pin connectors?

Because if they supplied them with anything else in the UK, you'd need to
buy an adaptor as well.


I'm not sure what you mean by that. Are you implying that it is no
longer legal in the UK to supply equipment with twin flex (and matching
2-pole connector)?

Nothing to do with legality, just practicability. If you want to sell
goods in the UK market, it is a pretty good idea to supply them with a
UK mains plug. Adaptors are for when you travel, not at home. One
current exception is mains-powered shavers (only a few left now), that
use a two-pin plug specifically designed for an isolated bathroom
connector.

A friend of mine has recently built a new house and her wiring has in
one room - quite legally - an old-fashioned 5-amp round pin socket.
