Cards

Term
Arc-Fault Circuit Interrupter (AFCI)?
Definition
Protects receptacles from internal arcs.
Term
Authority Having Jurisdiction (AHJ)??
Definition
city, state, township, county or municipality of the electrical installation.
Term
Bonded Conductor or Jumper?
Definition
A reliable conductor to ensure the required electrical conductivity between metal parts required to be "bonded" back to ground.
Term
Branch Circuit?
Definition
The circuit conductors between the final over-current device protecting the circuit and the outlet(s).
Term
Circuit Breaker?
Definition
A device designed to open and close a circuit by non-automatic means and to open the circuit automatically on a predetermined over-current without damage to itself when properly applied within its rating.
Term
Continuous Load?
Definition
A load where the maximum current is expected to continue for 3 hours or more.
Term
Garage?
Definition
A building or portion of a building in which one or more self-propelled vehicles can be kept for use, sale, storage, rental, repair, exhibition, or demonstration purposes.
Term
Ground?
Definition
The Earth.
Term
Ground Fault?
Definition
An unintentional, electrically conducting connection between an ungrounded conductor of an electrical circuit and the normally non-current-carrying conductors, metallic enclosures, metallic raceways, metallic equipment, or earth.
Term
GFCI (Ground Fault Circuit Interrupter)?
Definition
A device intended for the protection of personnel that functions to de-energize a circuit or portion thereof within an established period of time when a current to ground exceeds the values established for a Class A device.
Term
Grounding Electrode?
Definition
A conducting object (8' copper rod) through which a direct connection to earth is established.
Term
Listed?
Definition
Equipment, materials, or services listed with the UL (Underwriter Laboratories)
Term
Non-automatic?
Definition
Requiring human intervention to perform a function.
Term
Outlet?
Definition
A point on the wiring system at which current is taken to supply utilization equipment.
Term
Rainproof?
Definition
Constructed, protected,or treated so as to prevent rain from interfering with the successful operation of the apparatus under specified test conditions.
Term
Raintight?
Definition
Constructed or protected so that exposure to a beating rain will no result in the entrance of water under specified test conditions.
Term
Special Permission?
Definition
The written consent of the authority having jurisdiction.
Term
Switch, General-Use?
Definition
A switch intended for use in general distribution and branch circuits. It is rated in amperes, and it is capable of interrupting its rated current at its rated voltage.
Term
Ungrounded?
Definition
Not connected to ground or to a conductive body that extends the ground connection.
Term
Watertight?
Definition
Constructed so that moisture will not enter the enclosure under specified test conditions.
Term
Weatherproof?
Definition
Constructed or protected so that exposure to the weather will not interfere with successful operation.
Term
What are 4 locations where you will find GFCI's?
Definition
1. Kitchen
2. Garage
3. Outside Circuits
4. Bathroom
Term
When can rainproof, raintight, or watertight equipment fulfill the requirements for weatherproof?
Definition
Where varying weather conditions other than wetness, such as snow, ice, dust, or temperature extremes, are not a factor.
