Re: Wow!

Further to what Zorpman has replied, the polarized plug is also used in conjuction with the appliance on/off switch to help reduce shock hazards. I believe it is standard to have the hot lead switched at the appliance, this ensures that the appliance itself is not energized when turned off. If the nuetral wire was switched the appliance would always be energized, even when off, just waiting for a ground connection to cross it path.

The double insulation practice with polarized plugs ultimately means two appliance failures is required instead of just one for a shock hazard to exist (under intended usage)

I now have to go and pry that damn bagel out of the toaster.
