Failure to remove conduit burrs usually results in which of the following?

Failure to remove conduit burrs usually results in which of the following?

• A. Ground faults
• B. Arcing
• C. Short circuits
• D. Insulation damage

Answer: (A)

Sharp edges on conduit can nick or damage wire insulation as cables pass through. When the energized conductor’s insulation is compromised and it contacts the grounded metal conduit, current finds an unintended path to ground. That leakage path is what we call a ground fault. Because the conduit system is typically bonded to the grounding system, any contact between a live conductor and that grounded metal easily creates a ground-fault condition, which is why removing burrs is emphasized. While insulation damage or arcing can occur in other scenarios, the most direct and likely consequence here is a ground fault.
