5 de feb. de 2019 · For our typical AC electrical system, the purpose of the “Main Bonding Jumper” is to connect the equipment grounding conductors (E.G.C.) contained in each branch-circuit and the metal (conductive) service-disconnect enclosure to the Neutral Conductor of the electrical service.
7 de jul. de 2019 · The main bonding jumper connects the service neutral wiring to the grounding electrode conductor(s) (GEC), and also to the service enclosure (panel box). By connecting these three components together, it eliminates any voltage potential (current) between them.
1 de nov. de 1998 · The main bonding jumper performs three major functions: 1. Connecting the grounded service conductor to the equipment grounding bus or conductor and the service enclosure.
7 de mar. de 2024 · Main bonding jumpers, also known as bonding cables, are conductive cables used to establish electrical continuity between two or more components of an airplane. They are made of a highly...
21 de jul. de 2017 · Bonding Jumper, Main. Main bonding jumper is the connection between the grounded circuit conductor and the equipment grounding conductor at the service. A main bonding jumper is clearly shown in Figures 1 and 3.
11 de ago. de 2022 · The green screw is the main bonding jumper connecting the grounded busbar to the enclosure. A threaded hub (upper right) provides secure bonding to metal enclosures. The smaller bare copper conductor on the left is the equipment grounding conductor providing bonding.
The main bonding jumper is installed at the incoming service equipment. The system bonding jumper is any bonding jumper in a downstream separately derived system (transformer). For example if the facility receives 480 volts at the incoming service, there will be one main bonding jumper.
