Electricity- Source of energy that can be easily converted into light, heat or power

Ampere (Amp)- Unit of measure of the rate of flow of electricity through a wire

Volt- unit of measure of electrical pressure

National Electrical Code- handbook that sets the minimum standards for electrical wiring (Revised every 3 years)

Underwriters Laboratory (UL)- a laboratory that tests electrical wiring materials. A UL stamp ensures the product meets the minimum safety standards.

Circuit- complete path through which electricity flows; from power source to lamp and back to source

Fuse- safety device which burns through when current becomes too great

Circuit Breaker- safety device that trips rather than burning

Conductors- wires through which electricity flows

Service Entrance Panel (SEP)- panel located inside the house from which every circuit branches

Ground Fault Circuit Interrupter- protects form shock, can be installed at SEP or on receptacle

Branch Circuit- circuit between last breaker and one or more outlets

Feeder Circuit- circuit between the SEP and the fuse or circuit breaker protecting a branch circuit

Conduit- thin walled steel pipe used to protect electrical wires

Short Circuit- improper connection between the hot and neutral wires or between hot wires

The trip level of a GFCI is between 4 and 6 milliamps (thousandths of a amp)

GFCI disconnects in as little as 1/40th of a second

GFCI disconnects circuits in situations where a breaker or fuse would not

1) Within 6 feet of a sink 2) In garages except where not accessible 3) Unfinished basements 4) Crawl Spaces 5) Boathouses 6) Bathrooms

1) Single Pole- used for 120 circuits2) Double Pole- used for 240 circuits
