What should be done to a conduit end when fittings are not used?

• A. The end should be deburred to prevent wire insulation damage.
• B. The end should be painted to prevent corrosion.
• C. The end should be sealed with epoxy.
• D. The end should be seated in a ferrule.

Answer: (A)

When a conduit end is cut and no fittings are used, the edge can be jagged and sharp. Deburring the end removes burrs and smooths the edge, creating a safe, entry-friendly surface for conductors. This prevents insulation from being nicked or cut as wires are pulled through, which helps avoid insulation damage and potential electrical problems later. Painting or sealing the end isn’t needed for electrical protection and can even cause moisture-related issues, while seating a ferrule isn’t applicable when no fitting is used. So, deburring is the proper step.
