[BC] Hot and grounded chassis

[Dana Puopolo]

I remember a two prong non polarized line plug that had two 3AG type fuses in
it - one for each side of the line. You pushed them out via small holes on the
top if the plug.

The British/Irish practice of fusing the plug (up to 13 amps) might
make the most sense: this protects the flimsy line cord as well the
appliance, and puts the fuse in a location that's easy to access and
replace.

British plugs have ample volume for a fuse, but North American plugs
are probably too small, unless we want to start making them the size
of wall-warts.
