Re: Reverse Polarity
I usually tell my clients about lights and toasters. You can see how the parts are still energized from the diagram below. With a toaster, even after it's popped, you could still electrocute yourself trying to dig a bit of bread out with a fork. There's other reasons, but I've found this the easiest to explain.

I've always been told that once something's running it doesn't matter since its alternating current (AC) - but, of course, it's very dangerous as Richard's sketch shows.
