🔍 Key Concepts

• Grounding of electrical equipment cases and enclosures • How fault currents are safely carried away from personnel • Difference between static charge buildup and direct contact shock hazards

💭 Think About

• If an internal fault causes the transformer winding to contact the metal case, what happens if the case is grounded versus not grounded? • How does grounding the case affect the potential (voltage) difference between the case and nearby metal structures or earth? • Could grounding help with more than one type of hazard, and how would that relate to the answer choices given?

✅ Before You Answer

• Check whether grounding mainly protects against contact shock, static buildup, or possibly both. • Consider whether leaving the case ungrounded could allow it to rise to a dangerous voltage relative to ship’s ground/hull. • Think about standard marine electrical safety practices: are equipment cases typically both grounded and bonded to the hull/ground?
