bonding conductor การใช้

• The equipment earthing conductor is usually also used as the equipment bonding conductor ( see below ).
• The equipment bonding conductor is usually also used as the equipment earthing conductor ( see above ).
• Portable appliances with metal cases also have a bonding conductor in the flexible cable and plug connecting them to the distribution system.
• See NFPA 70, the U . S . National Electrical Code Handbook ( NEC ), section on bonding and ground for details on selecting the correct bonding conductor wire size.
• Some types of metal conduit may also serve as a useful bonding conductor for grounding ( earthing ), but wiring regulations may also dictate workmanship standards or supplemental means of grounding for certain types.
• The parts of a lightning protection system are air terminals ( lightning rods or strike termination devices ), bonding conductors, ground terminals ( ground or " earthing " rods, plates, or mesh ), and all of the connectors and supports to complete the system.
• According to the standard, proper infrastructure bonding requires the following elements : a telecommunications main grounding busbar ( TMGB ), telecommunications grounding busbars ( TGB ), telecommunications bonding backbone ( TBB ), grounding equalizers ( GE ), and a bonding conductor for telecommunications ( BCT ).
• The air terminals are typically arranged at or along the upper points of a roof structure, and are electrically bonded together by bonding conductors ( called " down conductors " or " downleads " ), which are connected by the most direct route to one or more grounding or earthing terminals.
• "Equipment bonding conductors " provide a low impedance path between non-current-carrying metallic parts of equipment and one of the conductors of that electrical system's source, so that if a part becomes energized for any reason, such as a frayed or damaged conductor, a short circuit will occur and operate a circuit breaker or fuse to disconnect the faulted circuit.
