Solid Grounding is used for Voltages?
Correct answer: C. Below 660 v
- A. Above 220 kv
- B. Above 11kv
- C. Below 660 v
- D. Below 115 v
Explanation
Solid grounding is generally used on low-voltage systems, where the neutral is directly connected to earth and fault current can be safely cleared by protective devices. The listed limit below 660 V represents this low-voltage practice.
