| 12250735947 | Appliance | Equipment designed for a particular purpose (for example, using electricity to produce heat, light, or mechanical motion). Appliances are usually self-contained, are generally available for applications other than industrial use, and are normally produced in standard sizes or types. | 0 | |
| 12250765846 | Bonding bushing | A special conduit bushing equipped with a conductor terminal to take a bonding jumper. It also has a screw or other sharp device to bite into the enclosure wall to bond the conduit to the enclosure without a jumper when there are no concentric knockouts left in the wall of the enclosure. | 1 | |
| 12250795997 | Bonding jumper | A bare or green insulated conductor used to ensure the required electrical conductivity between metal parts required to be electrically connected. Bonding jumpers are frequently used from a bonding bushing to the service-eqiuipment enclosure to provide a path around concentric knockouts in an enclosure wall, and they may also be used to bond one raceway to another. | 2 | |
| 12276274518 | Branch circuit | The portion of the wiring system extending beyond the final overcurrent device protecting a circuit. | 3 | |
| 12276293659 | Feeder | A circuit, such as conductors in conduit or a cable run, that carries current from the service equipment to a subpanel or a branch circuit panel or to some point in the wiring system. | 4 | |
| 12276336469 | Load center | A type of panelboard that is normally located at the service entrance of a residential installation. It usually contains the main disconnect. | 5 | |
| 12276360204 | Metal-clad (Type MC) cable | A factory assembly of one or more insulated circuit conductors with or without optical fiber members enclosed in an armor of interlocking metal tape, or a smooth or corrugated metallic sheath. | 6 | |
| 12276392385 | Nonmetallic-sheathed cable | A factory assembly of two or more instulated conductors enclosed within an overall nonmetallic jackets. Type NM contains insulated conductors enclosed within an overall nonmetallic jackets; Type NMC contains insulated conductors enclosed within an overall, corrosion-resistant, nonmetallic jackets; and Type NMS contains insulated power or control conductors with signaling, data, and communications conductors within an overall nonmetallic jackets. | 7 | |
| 12276455827 | Romex | General cable's trade mane for Type NM cable; however, it is often used generically to refer to any nonmetallic-sheathed cable. | 8 | |
| 12276480746 | Roughing in | The first stage of an electrical installation, when the raceway, cable, wires, boxes, and other equipment are installed. This is the electrical work that must be done before any finishing work can be done. | 9 | |
| 12276517535 | Service drop | The overhead conductors, through which electrical service is supplied, between the last power company pole and the point of their connection to the service facilities located at the building. | 10 | |
| 12276548054 | Service entrance | The point where power is supplied to a building (including the equipment used for this purpose). The service entrance includes the service main switch or panelboard, metering devices, overcurrent protective devices, and conductors/ raceways for connecting to the power company's conductors. | 11 | |
| 12276588960 | Service-entrance conductors | The conductors between the point of termination of the overhead service drop or underground service lateral and the main disconnecting device in the building. | 12 | |
| 12276611870 | Service-entrance equipment | Equipment that provides overcurrent protection to the feeder and service conductors, a means of disconnecting the feeders from energized service conductors, and a means of measuring the energy used. | 13 | |
| 12276654099 | Service lateral | The underground conductors through which service is supplied between the power company's distribution facilities and the first point of their connection to the building or area service facilities located at the building. | 14 | |
| 12276688314 | Switch | A mechanical device used for turning an electrical circuit on and off. | 15 | |
| 12276709135 | Switch leg | A circuit routed to a switch box for controlling electrical lights. | 16 |
