I would personally prefer to have a 13A fuse on an extension cord plugged into a 15A outlet so that the fuse would blow close to

Probably somewhere in this thread, the UK you have 30-32A ring circuits and current about half here with correspondingly small
cord wire so you need fuses in plugs. One fuse?

I would think that you'd want to open the (both) hot(s). Much like how you want a double poll breaker to open both hots on a 240

I think UK is 230V hot-neutral?
When I was growing up it was 240V live-neutral.
And changing to 230V would have been unthinkable due to the number of "why has my TV picture width shrunk" complaints which would
have occurred.
I may have heard the word "hot" in other contexts but not for AC power.
Also, some wiring installations still existed with live (hot) in red, neutral in black and earth (ground) in green.
It may be the case that 240V has now been reduced to 230V in line with the rest of Europe.
And these days most, perhaps all, electronics won't care about the difference.
In the UK I remember being asked to wire a plug for a 230V piece of equipment which had arrived from the US.
Fortunately by then I knew that black wasn't neutral in the US.
