What must be provided between conductors and armor in armored cable installation?

In armored cable installation, it's essential to use an approved insulating bushing between the conductors and the armor. This bushing serves as a protective barrier, ensuring that the sharp edges of the armor do not damage the conductors, which could lead to shorts or electrical failures. It also helps to maintain the integrity of the electrical system by providing additional insulation, which is crucial in preventing accidental contact between the conductors and the metal armor.

The use of an approved insulating bushing is a code requirement in many jurisdictions, including Colorado, as it enhances safety by minimizing the risk of electrical shock or fire hazards that could result from conductor damage. Proper installation techniques, including the use of bushings, ensure compliance with safety standards and regulations in electrical work. This practice is vital for maintaining the longevity and reliability of the installation.
