Appliances - 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. Bonding bushing - 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. 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-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.
