What do you do to a cable that has light corrosion on the inner strands?

• A. Repair it
• B. Patch with tape
• C. Replace it
• D. Leave as is

Answer: (C)

Light corrosion inside the strands means the conductor’s metal has begun to degrade, reducing the cross-sectional area and increasing resistance. Even if the outer jacket looks okay, damaged inner strands can fail under load, overheat, or cause intermittent faults. A repair or patch with tape cannot restore the conductor’s mechanical strength, electrical performance, or withstand vibration and environmental exposure. Leaving it as is is unsafe because it risks circuit failure and fire hazards. Replacing the cable ensures full current-carrying capability and proper insulation integrity. After replacement, verify continuity and insulation per the applicable maintenance procedures.
