What connects the grounded circuit conductor to the equipment grounding conductor at the service?

• A. Ground clamp
• B. Grounding rod
• C. Bonding jumper
• D. Safety switch

Answer: (C)

The connection between the grounded circuit conductor and the equipment grounding conductor at the service is facilitated by a bonding jumper. This component serves a crucial role in ensuring a low-impedance path for electric current to flow in case of a fault, which helps protect both equipment and personnel from electrical hazards. When a fault occurs, the bonding jumper provides a reliable means to clear the fault by allowing the circuit breakers to trip if an unintentional ground fault happens. This configuration effectively connects the neutral system (grounded circuit conductor) to the ground system (equipment grounding conductor), ensuring that both systems maintain a common reference point for safety and performance. In contrast, while other options like ground clamps and grounding rods are components related to grounding, they do not specifically provide the same direct connection between the grounded conductor and the equipment grounding conductor. Additionally, a safety switch does not perform this bonding function; rather, it serves as a means to disconnect power for protection or maintenance purposes.
