Where should a station AC surge protector be installed?
At the AC service panel
At an AC outlet
On the single point ground panel✓پاسخ درست
On a ground rod outside the station
توضیح
Surge protection works by keeping every conductor entering the station at the same potential during a surge, so the AC protector belongs on the single point ground panel alongside the feed line and control cable protectors. Placing it at an outlet or on a separate ground rod leaves a voltage difference between entry paths that can drive current through the equipment.
