Statistics show that fuse panels have a significantly higher
	risk of causing a fire than breaker panels.  This is usually
	due to the fuse being loosely screwed in, or the contacts
	corroding and heating up over time, or the wrong size fuse
	being installed, or the proverbial "replace the fuse with a
	penny" trick.

	Since breakers are more permanently installed, and have better
	connection mechanisms, the risk of fire is considerably less.

	Fuses are prone to explode under extremely high overload.  When
	a fuse explodes, the metallic vapor cloud becomes a conducting
	path.  Result?  From complete meltdown of the electrical panel,
	melted service wiring, through fires in the electrical
	distribution transformer and having your house burn down.
	[This author has seen it happen.]  Breakers won't do this.

	Many jurisdictions, particularly in Canada, no longer permit
	fuse panels in new installations.  The NEC does permit new
	fuse panels in some rare circumstances (requiring the special
	inserts to "key" the fuseholder to specific size fuses)

	Some devices, notably certain large air conditioners, require fuse
	protection in addition to the breaker at the panel.  The fuse
	is there to protect the motor windings from overload.  Check the
	labeling on the unit.  This is usually only on large permanently
	installed motors.  The installation instructions will tell you
	if you need one.
