Question
Where should a station AC surge protector be installed?
Answer Options
- A) At the AC service panel
- B) At an AC outlet
- C) On the single point ground panel
- D) On a ground rod outside the station
Correct Answer: C
Explanation
Surge protectors and transient suppressors are crucial for protecting radio equipment from lightning strikes and voltage spikes. To be effective, all protective devices (for AC power, DC power, and antenna feed lines) must reference the same, high-quality ground point to ensure coordinated activation.
Therefore, a station AC surge protector should be installed on the single point ground panel. This panel acts as the master ground bus for the station. When the AC surge protector clamps a voltage spike to ground, it ensures that all other protective devices on the single point ground are at the exact same potential, providing the most reliable and effective protection for the entire station.
