For a system to be considered grounded it must ____________?

• A. Be connected to water pipe
• B. Be connected to the building frame
• C. Have at least one conductor or point intentionally grounded
• D. Have multiple grounds

Answer: (C)

Grounding a system means there is an intentional connection from a conductor or a designated point to earth (or to a grounding electrode) so fault currents have a low-impedance path and the system voltage is referenced to earth. This intentional grounding establishes a stable reference and provides a safe path for fault current to travel, which helps protective devices operate quickly to clear faults. It isn’t about being connected to a water pipe or the building frame—those connections aren’t the defining feature of grounding and can be unreliable. Having multiple grounds isn’t required to be considered grounded; a single intentional grounding path is enough to establish the reference and fault current path, though additional grounds may exist for other design reasons.
