In this video, master electrician Scott Caron shares tips for preventing shocks and electrocution with Kevin O'Connor.
1. Circuit breakers protect a home's electrical system from an overload or short circuit.
2. An overloaded circuit is caused when too much electricity is drawn from a single circuit.
3. A short often occurs when a live wire is accidentally cut or damaged.
4. When a breaker senses an overload or short, it trips, cutting off power to that circuit.
5. To reset a tripped breaker, first switch it to the off position, then flip it on.
6. An arc-fault circuit interrupter protects against overloads and shorts, but also against small sparks or arcs that occur from a worn, damaged wire.
7. Ground-fault circuit interrupters (GFCI) are installed in damp locations, such as baths, kitchens, outdoors, basements and garages.
8. GFCI protect against ground faults, which occurs whenever electricity travels the path of ground. These devices prevent electrical shock should someone come in contact with a live circuit while wet or in a damp environment.
9. GFCI-protection is available in electrical receptacles, breakers or extension cords.
