"phase"? Here in HK, we call it "live". I think we just follow the
British naming conventions.

Strange, you failed to fail to understand what I meant. :-)

Down here we often also follow the Bwitish conventions, however,
in this case, the AC plugs and sockets usually mark the contact
in question with a letter "P" for "phase". And yes, it is the same as
your "live".

What? I think it is a "switch" that is triggered by electromagnetism
to switch of the circuit when the current exceeds the designed
threshold. You can switch it on again.

And they need not be restricted to the main electric panels.
Sometimes, you find it built into some appliances or their plugs.
Maybe, they're much more expensive than use-once fuses. So, fuses are
still a common place.
