A device that provides a means for connecting bonding conductors for communication systems to the grounding electrode system is called what?

• A. Intersystem bonding termination
• B. Bonding jumper
• C. Grounding electrode conductor
• D. Lightning arrestor

Answer: (A)

The key idea is creating a deliberate connection between the grounding system of electrical service and the grounding used for communication systems so they share the same ground potential. The term for the device that provides this specific connection point is the intersystem bonding termination. It’s a listed device designed to bond the bonding conductor from the communication system to the building’s grounding electrode system, ensuring a low-impedance path for fault and surge currents and meeting NEC requirements. A bonding jumper is a general bonding conductor used to connect metal parts, but it isn’t the defined device for interconnecting the communication system’s bond to the grounding electrode system. The grounding electrode conductor is the conductor that runs between the grounding electrode and the electrical system—it's a conductor, not a bonding device. A lightning arrestor protects equipment from surges and does not serve as the bonding point between systems.
