Question | Answer |
---|---|
Alternating Current (AC) | Electricity where the electrons flow in two directions |
Ampere or Amps | A unit of measurement for electrical current flow |
Bonding | The connection of two or more points to reduce any difference of potential |
Branch Circuit | The circuit conductors between the final overcurrent device protecting the circuit and the outlets. |
Circuit Breakers | Devices installed in the service panel of a home to limit the flow of electricity through a circuit. |
Code Corrections | Procedure designed to eliminate wiring conditions that do not meet National Electrical Code requirements and safety conditions. |
Direct Current (DC) | Flows in the same direction. (batteries) |
Duplex Receptacle | This is wired into an outlet box. And will allow you to plug in electrical devices. |
E.M.T. | Electrical Metallic Tubing |
Fixture | Any permanently connected light or other electrical device that consumes power. |
Fuses | connections blow apart and break the circuit if an overload or short occurs. |
GFI (Ground Fault Interrupter) | A device whose function is to break the electrical circuit to the load when there is a fault current to ground. |
Grounded | Connected to earth or to some conducting body that serves in place of the earth. |
Grounded Conductor | A system or circuit conductor that is intentionally grounded. |
Grounding Conductor | A conductor used to connect equipment or the grounding circuit of a wiring system to a grounding electrode or electrodes. |
Inverter | An inverter takes DC power from a 12-volt battery and converts it to household AC power. |
Junction Box | A metal or plastic box used to enclose splice connections. |
OHM | The unit of measurement for electrical resistance. R=E/I. |
Outlet | A point on a wiring system at which current is taken to supply electrical devices. A receptacle is placed in an outlet. |
Pigtail | A short, added piece of wire connected by a wire nut. Commonly used to extend or connect wires in a box. |
Receptacles (Duplex) | Power sources located throughout a building to provide electricity where needed. |
Romex | Plastic coated cable. Has a soft flexible jacket. Used mainly for indoor wiring in residential buildings. |
Surge | A short duration high voltage condition. May last for several cycles. |
Switches | Circuit interruption devices used to control the flow of electricity to lights, appliances, and outlets. |
Thermostat | A low voltage electronic switching device that monitors temperatures inside the home and turns on and off the heating or cooling system in the home. |
Three Phase Power | Three separate outputs from a single source with a phase differential of 120 electrical degrees between any two adjacent voltages or currents. |
Type U.F. Cable | This type of cable is used mostly for direct burial in the earth. This is a branch circuit cable that also can be used for outside wiring. |
Volt | A unit that measures the amount of electrical pressure. |
Watt | A unit that measures the amount of electrical power. |
Wirenut | A device used to connect spliced wires together. |
Wiring | A distribution network of wire that conducts electricity to receptacles, switches and appliances throughout a building/home to provide electricity where needed. |
