What type of conductor connects non-current-carrying parts of equipment to a grounding system?

The type of conductor that connects non-current-carrying parts of equipment to a grounding system is the grounding conductor. Grounding conductors serve a critical safety function by providing a low-resistance path for electrical current to flow back to the ground in the event of a fault. This helps to prevent electric shock and equipment damage by enabling overcurrent protection devices, like circuit breakers or fuses, to operate effectively and disconnect power when necessary.

By connecting non-current-carrying components, such as metal enclosures of electrical equipment, to the grounding system, the grounding conductor helps ensure that any stray voltage or fault current is safely directed to the ground. This process not only protects individuals from electric shock but also helps maintain the integrity of the electrical system and minimizes the risk of fire hazards.

The other types of conductors listed—service conductor, feeder conductor, and branch circuit conductor—are designed for delivering current to various parts of the electrical system rather than connecting to grounding systems. Service conductors bring electricity from the utility service to the premises, feeder conductors distribute power from the service equipment to various parts of the installation, and branch circuit conductors supply power to individual loads or receptacles. These functions are different from the role of a grounding conductor, which
