What is the minimum radius of the curve for bends in type AC cable?

• A. 3 times the diameter of type AC cable
• B. 4 times the diameter of type AC cable
• C. 5 times the diameter of type AC cable
• D. 6 times the diameter of type AC cable

Answer: (C)

The minimum radius of the curve for bends in type AC cable is established to prevent damage to the cable and to ensure optimal performance and longevity. Selecting a minimum bend radius is crucial because a bend that is too tight could lead to insulation damage, conductor breakage, or impaired electrical performance due to stress on the cable's structure. The specific guideline for type AC cable indicates that the minimum bend radius should be at least 5 times the diameter of the cable. This guideline is derived from both manufacturer recommendations and industry best practices, which ensure that cables maintain their integrity and do not experience undue stress when installed in curved configurations. Choosing a bend radius less than this can lead to issues such as increased voltage drop, potential shorting, and reduced lifespan. Therefore, adhering to the 5 times the diameter standard helps in maintaining the reliability and functionality of type AC cable installations.
