• ALIVE (LIVE)- Electrically connected to source of potential differences or electrical charge so as to have a potential difference form that of the earth.
• AMPACITY- The current in amperes a conductor can carry continuously under the conditions of use without exceeding its temperature rating.
• BRANCH CIRCUIT- The circuit conductors between the final overcurrent device protecting the circuit and the outlet(s).
• BRANCH CIRCUIT, APPLIANCE- A branch circuit supplying energy to one or more outlets to which appliances are to be connected; such circuits to have no permanently connected lighting fixtures not part of an appliance.
• BRANCH CIRCUIT, GENERAL PURPOSE- A branch circuit that supplies a number of outlets for lighting and appliances.
• BRANCH CIRCUIT, INDIVIDUAL- A branch circuit that supplies only one utilization equipment.
• BUSWAY- An approved, completely assembled metal troughing and fitting therefore, containing bare conductors intended for use as feeders, the conductors being suitably supported on insulators.
• CABINET- An enclosure designed either for surface or flush mounting and provided with a frame, mat, or trim in which a swinging door or doors are or may be hung.
• CIRCUIT BREAKER- A device designed to open and close a circuit by a non-automatic means and to open the circuit automatically with a pre-determined overcurrent without injury to itself when properly applied within its rating
• DEAD- Free from any electric connections to a source of potential difference from that of the earth. The term is used only with reference to current carrying parts which are sometimes alive.
• DEVICE- A unit of an electrical system which is intended to carry but not utilize electric energy.
• DISCONNECTING MEANS- A device, or group of devices, or other means by which the conductors of a circuit can be disconnected from their source of supply.
• FITTING- An accessory such as a locknut, bushing, or other part of a wiring system that is intended primarily to perform a mechanical rather than an electrical function
• FLAME-RETARDANT – So constructed or treated that it will not readily burn or convey flame.
• MOISTURE RESISTANT – So constructed or treated that exposure to a moist will not readily cause injury or harmful change in quality.
• JUNCTION BOX- A box with a blank cover which serves the purpose of joining different runs of raceway on cable, and provided with sufficient space for connection and branching of the enclosed conductors.
• OVERLOAD- Operation of equipment in excess of normal, full load rating, or of a conductor in excess of rated ampacity which it persists for a sufficient length of time, would cause damage or dangerous overheating. A fault, such as short circuit or ground fault, is not an over load.
• SERVICE DROP- The overhead service conductors from the last pole or other aerial support to and including the splices, if any, connecting to the service entrance conductors at the building or other structure.
• SERVICE-ENTRANCE CONDUCTORS, OVERHEAD SYSTEM- The service conductors between the terminals of the service equipment and a point usually the building, clear of building walls, where joined by tap or splice to the service drop.
• SERVICE LATERAL- The underground service conductors between the street main, including any risers at a pole or other structure or from transformers, and the first point of connection to the service- entrance conductors in as terminal box or meter or other enclosure with adequate space, inside or outside the building wall.
• SERVICE RACEWAY- The raceway that encloses the service-entrance conductors
• PANELBOARD- It contains the circuit protective device such as the fuse or circuit breaker. It also consists of a set of busbars where the protective devices are connected.
• SERVICE-ENTRANCE CONDUCTORS, UNDERGROUND SYSTEM- The service conductors between the terminals of the service equipment and the point of connection to the service lateral.
