What steps should you take after removing a capacitor from service?

• A. Disconnect from power and wait five minutes
• B. Short (shunt) out the bushings and ground
• C. Dispose of it immediately
• D. Check for visible damage

Answer: (A)

After removing a capacitor from service, the first and most important step is to disconnect it from power and allow a waiting period to ensure safety. Capacitors store electrical energy, which can pose a significant risk of shock or electrical hazard if they are not adequately de-energized before handling. Waiting at least five minutes is a standard practice, as it allows time for any remaining charge to dissipate naturally. While shunting out the bushings and grounding the capacitor is also an important safety measure, it would typically be done following the disconnection and prior to any physical handling. Immediate disposal of a capacitor without proper evaluation could lead to environmental issues and violates disposal regulations. Checking for visible damage is also crucial, but it should come after ensuring the capacitor is safely disconnected and de-energized to prevent any risk during inspection. Therefore, ensuring that the capacitor is disconnected from power and waiting allows for a safer approach to handling the equipment further.
