In a typical electrical installation, to which point is the equipment grounding conductor connected on equipment?

• A. To the equipment's live terminal.
• B. To the equipment's neutral terminal.
• C. To a separate floating node.
• D. To the equipment's grounding terminal.

Answer: (D)

The main idea is that the equipment grounding conductor is bonded to the equipment through a designated grounding terminal. This creates a low-impedance path to earth so that any fault current can return to the source and trip the protective device, keeping the metal enclosure at earth potential and reducing shock risk. It should not be connected to a live or neutral terminal, because that would energize the chassis during normal operation or faults. Neutral is only bonded to earth at service equipment, not at each device. A separate floating node wouldn’t provide a grounding path at all. So the equipment grounding conductor goes to the equipment’s grounding terminal.
