What does a grounding conductor connect to within an electrical installation?

• A. Only to the circuit breaker
• B. Metal parts of equipment and grounding electrode
• C. Only to the neutral conductor
• D. Device enclosures

Answer: (B)

A grounding conductor is an essential component in electrical installations that serves to protect both equipment and individuals from electrical faults. It establishes a connection to the metal parts of electrical equipment and to the grounding electrode. The grounding electrode is typically a rod or plate that is buried in the ground to provide a safe path for electrical faults to dissipate safely into the earth. By connecting to the metal parts of equipment, the grounding conductor ensures that, in the event of a fault, the electrical current flows through the grounding system instead of through a person who might touch the equipment. This significantly reduces the risk of electric shock. Furthermore, the connection to the grounding electrode is crucial as it helps maintain the electrical system's stability and facilitates the operation of protective devices, such as circuit breakers and fuses, by providing a clear path for fault currents. This dual connection to both metal parts of equipment and a grounding electrode is key to ensuring safety and compliance with electrical codes.
