NCCER ELECTRICAL MODULE 11 COMPLETE QUESTIONS AND CORRECT ANSWERS | GRADED AND THE LATEST SERIES

Question: Bonding bushing Ans: A special conduit bushing equipped with a conductor terminal to accept 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. Question: Bonding jumper Ans: 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-equipment enclosure to provide a path around concentric knockouts in an enclosure wall, and they may also be used to bond one raceway to another. Question: Branch circuit Ans: The portion of a wiring system extending beyond the final overcurrent device protecting a circuit Question: Feeder Ans: 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 Question: Load center Ans: A type of panelboard that is normally located at the service entrance of a residential installation. It sometimes contains the main disconnect. Question: Metal-clad (Type MC) cable Ans: A factory assembly of one or more insulated circuit conductors with or without optical fiver members enclosed in an armor of interlocking metal tape, or a smooth or corrugated metallic sheath Question: Nonmetallic-sheathed (Type NM) cable Ans: A factory-assembly of two or more insulated conductors enclosed within an overall nonmetallic jacket. Type NM contains insulated conductors enclosed within an overall nonmetallic jacket; Type NMC contains insulated enclosed within an overall, corrosion-resistant, nonmetallic jacket; and Type NMS contains insulated power or control conductors with signaling, data, and communications conductors within an overall nonmetallic jacket. Question: Romex Ans: General Cable's trade name for Type NM cable; however, it is often used generically to refer to any nonmetallic-sheathed cable Question: Roughing in Ans: 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 Question: Service drop Ans: The overhead conductors, through which electrical service is supplies. Between the last power company pole and the point of their connection to the service facilities located at the buildin
