Which type of equipment grounding conductor is typically furnished with some types of AC and MC cable to establish an isolated ground?

The type of equipment grounding conductor that is typically furnished with certain types of AC (Armored Cable) and MC (Metal-Clad Cable) is insulated. Insulated equipment grounding conductors are used in these cable types to establish an isolated ground connection while minimizing potential interference from other electrical conductors. Insulating the grounding conductor helps to prevent unwanted interactions with other electrical signals and ensures that the grounding system functions effectively without generating electrical noise.

Insulated conductors also offer better protection against environmental factors such as moisture and corrosion, which can affect bare conductors. While bare and covered conductors are used in various applications, the utilization of insulated conductors in AC and MC cables is specifically designed to enhance safety and system performance by preventing contact with other wiring and reducing the risk of ground faults. This is crucial in maintaining the integrity of the grounding system and ensuring that any fault currents are safely routed to ground without interference from surrounding conductors.
