What is primarily used to prevent shock hazards in separately derived systems?

The primary function of a grounding electrode conductor in separately derived systems is to ensure that there is a safe pathway for fault current to travel back to the ground. This is crucial in preventing shock hazards because it helps to stabilize the voltage during a fault condition.

A separately derived system, such as a generator or transformer, creates its own grounding reference and requires a proper grounding connection to safely dissipate any fault currents. The grounding electrode conductor connects this system to the earth. In the event of a fault, the grounding electrode conductor provides a low-impedance path to ground, ensuring that any electrical energy is safely directed away from individuals and equipment, thereby reducing the risk of electric shock.

In contrast, the other options serve different protective functions but do not specifically address the prevention of shock hazards in the context of separately derived systems. The system bonding jumper ensures that different grounding systems are electrically connected, promoting system stability. Overcurrent protection devices are designed to interrupt the circuit in the event of excessive current flow but do not directly mitigate shock risks. The equipment grounding conductor provides a path for ground faults but does not specifically relate to the grounding of the separately derived system itself.

Thus, the grounding electrode conductor is essential for establishing a safe grounding connection in these systems,
