Increased in length

Hindered

Damaged

Bends in nonmetallic cables should be made to ensure the cable is not damaged. Nonmetallic cables are constructed from materials that can be susceptible to physical stress and environmental factors. Poor bending practices can lead to issues such as insulation breakdown or conductor failure, which can compromise the cable's integrity and safety.

To maintain the performance and lifespan of nonmetallic cables, it is essential to follow manufacturer guidelines regarding bend radius and installation practices. Ensuring that bends are smooth and within specified limits helps to prevent damage, allowing the cable to function properly without the risk of shorts or electrical failures. This principle underscores the importance of careful handling and installation in electrical work, aligning with the requirements set out in the National Electrical Code (NEC).
