An electrical connection between the wiring of an electric motor and its metal frame is known as what?

🔍 Key Concepts

• Safety grounding in electrical systems • Purpose of connecting metal frames or cases to the ship’s electrical return path • Difference between magnetic effects (like flux and eddy currents) and protective wiring connections

💭 Think About

• Ask yourself: What is the main safety reason for bonding the metal frame of a motor to a specific point in the electrical system? • Which of these terms refers specifically to a protective connection path for fault current, not a magnetic or AC characteristic? • If a live wire inside the motor touches the frame, what connection must exist so a protective device (fuse/breaker) will operate correctly?

✅ Before You Answer

• Identify which choice describes a protective conductive path between equipment and the system reference point (often the ship’s hull or return bus). • Eliminate any options that refer mainly to magnetic fields or AC resistance rather than a physical safety connection. • Confirm which term is commonly used in marine electrical safety to describe bonding exposed metal parts to prevent shock.
