AFCI and GFCI Outlets and Breakers

As new technology brings us new tools to make our lives easier, it also provides new devices to keep us safer in our homes. Anthony Perry's Inspections checks and recommends GFCI and AFCI circuit protection for every home, GFCI protected electrical receptacles and AFCI protection circuit breakers are small technological wonders. They are outlets and / or circuit breakers that contain some extra specialized and micro-miniaturized electrical circuits that can detect the specific, characteristic signs of household electrical current problems that are present when certain dangerous situations occur. When the detect such conditions, they automatically shut down the electricity, providing an extra layer of safety and, possibly saving a life in the process. Regular circuit breakers are designed to protect the house's electrical system, not people! The amount of electricity that is needed to kill a human being is thousands of times less than the amount that will 'trip' a regular circuit breaker.

Fuses and Circuit Breakers - Fuses and circuit breakers, also called "over current devices" are used in your house's electrical system in order to guard against too much electrical current running through the house's wiring. As electrical current flows through the wires, it loses some of its power because the wires have an electrical resistance. This is safe, but if too much current flows, based upon the wires diameter and resistance rating, the wire may get too hot and start a fire. To prevent this, fuses or circuit breakers will detect when too much electricity is flowing and will blow (fuses) or trip (circuit breakers). When this occurs, it usually means that someone has tried to put too may electrical devices on one circuit. Fuses an circuit breakers are designed to protect the house's wiring from fire. They are not designed to protect the people in the house from being electrocuted. That is where GFCI and AFCI devices come into play.

GFCI Electrical Outlets - A GFCI outlet (GFCI stands for Ground Fault Circuit Interrupt) is a special electrical outlet device that provides much greater protection from electrical shock than a standard electrical outlet does. Think of a GFCI outlet as a small, ultra sensitive circuit breaker that is built right into the outlet but it does not guard against fire, but against human electrocution. it should be called an 'Anti-Electrocution Device'. Here's how it works.

When the amount of electrical current coming out of the 'hot' prong of the outlet (the smaller slot) is just 5/1000 of an amp different from the amount of electrical current coming back into the outlet on the 'neutral' prong (the larger one), the GFCI outlet will 'trip', i.e. shut down the outlet. In such a case, the GFCI outlet senses that it is putting out more electricity than it getting back. The only place that this missing electrical current can be going is to another source of electrical ground, which is probably a person! GFCI outlets are now required to be used anyplace in your house where there is a close proximity to the grounding of a human being. Such places are; all kitchen counter tops and islands, within 6' of other sinks or water sources, bathrooms, unfinished basements areas, garages and all outdoor outlets.

Please Note: If your house was built before GFCIs were required, local building codes do not necessarily require them, but proper home safety does! Going beyond the minimum safety requirements of mere local building codes, to the higher standards of safety, is part of what a professional InterNACHI home inspector does.

Besides, having your older house retrofitted with GFCI protection is inexpensive and easy. Why would you not want to protect your family from electrocution? GFCI protection can be installed with GFCI receptacles or with the whole circuit being equipped with GFCI Circuit breaker.

AFCI Electrical Outlets - AFCI protection is much like a GFCI outlet, but it protects against an entirely different potential danger. Sometimes, certain types of electrical appliances will be used to convert electricity into heat. Sometimes, these devices will also cause heating where the device plugs into the wall. This is called arcing. You sometimes see it when you quickly unplug a heating appliance, like a clothing iron, from an outlet while it is switched on. Electrical arcs can also be caused when someone drives a nail through a wire that is in a wall (like when hanging a picture) or by mice or squirrels who like to chew on electrical wiring.
