New technology is usually a good thing, except when it has to be supported by old wiring. Modern appliances use more energy than those of even a generation ago. The additional strain on aging electrical systems leaves them vulnerable to arc faults and the renter or homeowner at risk for an apartment or house fire.
What is Arc Fault?
An arc fault is an extremely hot, dangerous, short burst of electrical energy through the air between electrical conductors. Arc faults can cause fire by igniting surrounding combustible materials.
