What is a good way to guard against electrical shock at your station?

D
Answer
Electrical, RF, and mechanical safety
Type
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

Answer Notes

Protecting yourself from electrical shock requires a comprehensive approach to safety at your station. Using three-wire cords ensures that the chassis of your equipment is tied to the electrical safety ground, providing a safe path to ground for stray currents. Connecting all AC-powered equipment to a common safety ground prevents hazardous voltage differences from developing between different pieces of gear. Furthermore, discharging high-voltage capacitors is critical before servicing, as they can hold a lethal electrical charge long after the equipment is unplugged. Because all of these practices address different critical aspects of electrical safety—proper handling of AC mains, preventing chassis potential differences, and managing stored DC energy—all the choices provided are correct and necessary for a safe station.
