Trader summed it up nicely. If you have the polarity swapped on your
toaster, the switch is opening the neutral and when you stick the fork
in there to get the bagel out, it will light you up.


That Stormin guy said much the same. The toaster
shell should either be isolated, or grounded.

I read once toaster shells aren't grounded because of
what could happen if people hit the heating element pushing
the toast down. Forks? Knives?



Could be isolated. I've never put a VOM on a
toaster, might do that some day for raw
excitement. My toaster has two wire cord and
plug, so the shell is probably isolated. Does
anyone have a three wire corded toaster to test?
With the possible exception of a commercial unit I don't think there
has been a grounded toaster sold in North America in over 40 years -
and I have NEVER seen one that was not isolated from the factory..
Some of the better ones even switched both wires years ago.

Does switching both wires increase the chance of GFCI's tripping?

I'm picturing a situation where there's a lag between the opening of hot
vs. the neutral. Wouldn't the GFCI sense that?

Nope. Dr Kirchoff says the current in a circuit is equal everywhere if
there is only one path. When the first switch opens, the current
stops.
