Technician exam question T0A06
Subelement T0, SAFETY· Group T0A
What is a good way to guard against electrical shock at your station?
- A.Use three-wire cords and plugs for all AC powered equipment
- B.Connect all AC powered station equipment to a common safety ground
- C.Ensure all capacitors used for high-voltage DC are fully discharged before working inside equipment
- D.All these choices are correct (correct answer)
WhyUsing three-wire cords and plugs, connecting equipment to a common safety ground, and fully discharging high-voltage capacitors before working inside equipment all guard against electrical shock at your station. Three-wire grounded cords, a common safety ground tying all station equipment together, and fully discharging high-voltage capacitors before opening equipment are all genuine, standard ways to reduce shock risk at a station, so all three are correct, answer D. Relying on just one of A, B, or C would leave out other real, independent protections a well-run station should have in place.
