I remember when these first came out, building codes required them on the
duplex outlet circuits to bedrooms so electric blankets didn't cause fires. Now
a lot of states want them everywhere.
Typical government/committe expansion of what was originally a good idea
(maybe).
Same with GFICs used to be only in bathrooms, expanded to kitchens near a sink,
now ALL countertops with duplex outs in a kitchen need them even if not near
the sink.
GFIs don't need a ground to work, they sense a difference in in/out current. In
some older homes people install them in the old two wire dulpex outlets so they
have protection and a 3 prong outlet.
