What must be done to abandoned electrical circuits?

• A. De-energized, or taken out of service if no further use is intended
• B. Left in place
• C. Reused later
• D. Covered with tape and left energized

Answer: (A)

When a circuit is abandoned, the energy must be removed to prevent hazards. De-energizing it eliminates the voltage and stored energy, reducing the risk of electric shock, arc flash, or fire if someone accidentally energizes or contacts it later. If there is no plan to use the circuit again, it should be taken out of service or physically disconnected so it cannot be energized. Leaving the circuit in place, reusing it later without proper de-energizing, or simply covering it with tape while it remains energized keeps the hazard alive and can lead to unexpected energization or faults. Proper practice focuses on making sure abandoned circuits are no longer energized and are clearly out of service, sometimes with lockout/tagout as an added safety measure.
