What is the minimum bend radius for Type AC Cable in order to prevent damage?

The minimum bend radius for Type AC (Armored Cable) is critical to prevent damage during installation and throughout the cable's lifespan. The correct answer, which is 5 times the diameter, is established based on the need to maintain the integrity of the cable's construction. This specification ensures that the cable does not experience excessive stress that could lead to insulation breakdown, conductor failure, or overall degradation of the cable's performance.

The rationale behind this requirement is that bending a cable too sharply can create points of strain, especially on the conductors and insulation. By adhering to a minimum bend radius of 5 times the diameter, installers ensure that the cable is not subjected to undue stress, thereby preserving its long-term reliability and functionality. Maintaining this radius also helps to ensure compliance with relevant electrical codes and standards, which are designed to promote safety and durability in electrical installations.
