Where should a station AC surge protector be installed?
- A.At the AC service panel
- B.At an AC outlet
- C.On the single point ground panel (correct answer)
- D.On a ground rod outside the station
WhyA station AC surge protector should be installed on the single point ground panel. A station's AC surge protector should be installed on the single point ground panel, the central grounding point that ties the station's various protective and grounding systems together so surge energy has one consistent, low-impedance path to reference, answer C. Installing it only at the service panel, at an ordinary outlet, or on an outdoor ground rod in isolation doesn't integrate it into the station's overall single-point grounding scheme.
