After repairing a conductor, which option is the correct step before energizing again?

• A. Energize immediately after repair.
• B. Visual inspection.
• C. Document the repair in the log.
• D. Retest the repair.

Answer: (D)

When a conductor is repaired, you must verify that the repair actually restored the circuit’s electrical integrity before turning power back on. Retesting is the only way to confirm continuity, proper resistance, and insulation integrity, catching hidden faults that a quick look won’t reveal. Simply visually inspecting won’t guarantee the repair will withstand energized conditions, and energizing immediately poses a safety risk. Documenting the repair is important for records, but it typically follows a successful retest to provide objective proof the repair passed the tests.
