Ground-fault protection of equipment is not permitted for fire pump circuits or required for a continuous industrial process where a non-orderly shutdown would introduce additional hazards.

• A. True
• B. False
• C. Both statements are true
• D. Not applicable

Answer: (A)

Ground-fault protection of equipment is designed to automatically disconnect equipment when a ground fault occurs, reducing shock risk and equipment damage. However, there are deliberate exceptions for systems where a sudden shutdown could create greater danger than the ground fault itself. Fire pump circuits are not permitted to have GFPE because preserving the pump’s ability to operate during an emergency is essential for effective firefighting; a ground-fault tripping the pump could leave a building without water and firefighting capability at a critical moment. Similarly, for a continuous industrial process where an abrupt shutdown would introduce additional hazards, GFPE is not required, since an automatic disconnection could worsen the situation or interrupt a hazardous process in an unsafe way. In all other applicable circuits, GFPE remains a key protection, but these specific scenarios are exempt because safety and reliability take precedence in those contexts.
