Well, to confuse you even more, _all_ European EQ is only ment to
have _one_ switch and _one_ fuse inside the circuit - and there is
basicly _no_ distingtion between 'hot' or 'neutral'
> They expect the neutral to be at / near ground.
Acording to actual EU (and local) regulations it is not allowed
for devices to expect any single wire to have a special potential,
with an exception of the PG of course.

A fuse will never protect _you_ nor the device. It is only ment to
protect the house/the installation. A devices fuse solves still its
purpose (by means of the codes) if it is not blown while parts of
the device are damaged thru an electrical fault, as long as these
parts can't cause any further damage outside the device (liek fire).
And for this, there is no logical need to have it in a special position
of the circuit. The same is true for switches.
Alas, don't forget, Neutral is by definition _not_ Ground (PG). A
proper system (house instalation) is only supposed keep it that way.
And just remember all the 2 wire plugged gear - they also have in
almost all cases only one switch and one fuse - and you can plug
them either way. We are still talking about AC.

P.S.: Sallam: I guess this could give a nice speach for VCF (Europe).
