What is the required securing distance for Type AC armored cable?

The required securing distance for Type AC armored cable is 4.5 feet. This distance is specified in the National Electrical Code (NEC) to ensure that the cable is adequately supported, minimizing the risk of damage due to tension, strain, or movement. Securing the cable at this interval helps to ensure safety and compliance with electrical standards, which is critical for maintaining the integrity of the installation. Proper securing is essential in preventing issues such as wear and tear, which can lead to electrical hazards like shorts or fires. This requirement reflects best practices for installation and is based on factors such as the physical nature of the cable and typical installation scenarios encountered in residential and commercial wiring.
