What is the minimum bending radius for type AC cable?

• A. 2 times the diameter
• B. 3 times the diameter
• C. 4 times the diameter
• D. 5 times the diameter

Answer: (D)

The minimum bending radius for Type AC cable is correctly defined as 5 times the diameter of the cable. This requirement ensures that the cable maintains its integrity and performance when subjected to bending. If the bending radius is too small, it can cause internal damage to the conductors, such as insulation breakdown or conductor breakage, which can lead to safety hazards, including short circuits or electrical fires. Adhering to the specified bending radius is also critical in maintaining the cable's electrical characteristics and prolonging its life. In applications where the bending radius is not taken into consideration, there is also the potential risk of exceeding the mechanical limits of the cable’s components, further increasing the likelihood of equipment failure. Thus, following the requirement of a minimum bending radius of 5 times the diameter is crucial for safe and reliable electrical installations.
