An aspect that I just heard of yesterday, from one of our Product Safety
engineers, is that Australia, Argentina, and the People's Republic of China have
what looks like the identical plug. The Australian plug is used over much of
the South Pacific. The prongs for the Chinese plug are 1mm longer than the
prongs in the Australian plug. The prongs in the Argentina plug are 1mm longer
that the prongs in the Australian plug, AND hot and neutral are swapped!
