In a service grounding system, which of the following is a grounded conductor?

In a service grounding system, which of the following is a grounded conductor?

• A. neutral conductor
• B. equipment grounding conductor
• C. grounding electrode conductor
• D. main bonding jumper

Answer: (A)

In service grounding, the grounded conductor is the neutral conductor because it is the conductor that is intentionally connected to earth at the main service disconnect to establish a reference potential for the system. The equipment grounding conductor is there to provide a fault-current path back to the source and is not the normal grounded conductor. The grounding electrode conductor links the system to the earth, but it does not carry normal operating current as the grounded conductor. The main bonding jumper bonds the neutral to the grounding electrode system at the service, but it itself is not the grounded conductor.
