The Facts:

	People have been killed by 100 volts AC. Any electrical device used on a house wiring circuit can be fatal under certain conditions.
	It only take less than 1% of the available current on a standard outlet to be potentially dangerous.
	GFCI detects when as little as 8 thousandths of an amp of current is flowing anywhere but thru the outlet (to ground somehow). When it detects potentially hazardous ground faults and quickly disconnecting power from the circuit.
	Condee Cooling & Electric recommends the people of Marco Island that any electrical device in damp locations have a GFCI outlet or breaker installed on that circuit.

GFCI protection is required for most outdoor receptacles (since 1973), bathroom receptacle circuits (since 1975), garage wall outlets (since 1978), kitchen receptacles (since 1987), and all receptacles in crawl spaces and unfinished basements (since 1990).

Owners of homes that do not have GFCls installed in all those critical areas specified in the latest version of the Code should consider having them installed. For broad protection, GFCI circuit breakers may be added in many panels of older homes to replace ordinary circuit breaker.

Circuit breaker and receptacle-type GFCIs may be installed in your home by a qualified electrician. Receptacle-type GFCIs may be installed by knowledgeable consumers familiar with electrical wiring practices who also follow the instructions accompanying the device. When in doubt about the proper procedure, contact a qualified electrician. Do not attempt to install it yourself.
