GFCIs are generally not used on circuits that (a) don't pose a
	safety risk, and (b) are used to power equipment that must run
	unattended for long periods of time.  Refrigerators, freezers,
	and sump pumps are good examples.  The rationale is that GFCIs
	are sometimes prone to nuisance trips.  Some people claim that
	the inductive delay in motor windings can cause a momentary
	current imbalance, tripping the GFCI.  Note, though, that most
	GFCI trips are real; if you're getting a lot of trips for no
	apparent reason, you'd be well-advised to check your wiring
	before deciding that the GFCI is broken or useless.
