The minimum bending radius for type AC cable is determined by the need to maintain the integrity and functionality of the cable while preventing damage during installation and use. For type AC (Armored Cable), the guideline states that the bending radius should be a minimum of five times the diameter of the cable. This ensures that the cable's conductors and insulation are not stressed beyond their capacity, which could lead to damage or shorts.

Maintaining this minimum bending radius is crucial for ensuring the durability of the cable in various installations. Exceeding this minimum radius might be acceptable and beneficial, as it can further reduce strain and enhance longevity, but not adhering to this guideline can result in complications such as reduced performance or increased failure rates.

The incorrect options reflect smaller bending radii, which do not provide adequate protection for the cable. For example, specifying the minimum radius as two or three times the diameter could lead to kinks or other forms of damage, ultimately compromising the cable's function and safety. Hence, recognizing five times the diameter as the appropriate standard is vital for the installation of type AC cable.
