What is a good way to guard against electrical shock at your station?
Use three-wire cords and plugs for all AC powered equipment
Connect all AC powered station equipment to a common safety ground
Ensure all capacitors used for high-voltage DC are fully discharged before working inside equipment
All these choices are correct✓Richtige Antwort
Erklärung
All three practices address different shock paths: a three-wire cord and plug keeps equipment chassis at ground potential, bonding station equipment to a common ground prevents dangerous voltage differences between chassis, and discharging high-voltage capacitors removes stored energy that persists after power is off. So the all-of-these answer is correct.
