What term describes a system intended to protect equipment from damaging line-to-ground fault currents by opening all ungrounded conductors of the faulted circuit?

• A. Ground Fault Protection of Equipment
• B. Overcurrent Protection
• C. Arc Fault Protection
• D. Short-Circuit Protection

Answer: (A)

Ground fault protection of equipment safeguards equipment by detecting a line-to-ground fault and then opening all ungrounded conductors of the affected circuit, isolating the fault to prevent damage or fire. This approach ensures every energized conductor in that circuit is disconnected, so the fault cannot continue or re-energize connected parts. Other protections describe different goals: overcurrent protection covers excessive current in general, arc fault protection targets arcing events, and short-circuit protection deals with high current events but doesn’t inherently guarantee isolation of the entire faulted circuit. Because the requirement focuses on removing energy from every hot conductor in the faulted circuit to protect equipment, the correct term is Ground Fault Protection of Equipment.
