Type MC cable should not be used in which type of conditions?

Type MC (Metal Clad) cable is a flexible, armored electrical cable that provides protection against physical damage and certain environmental conditions. However, it is crucial to understand its limitations.

Metal Clad cable should not be used in destructive corrosive conditions because the metal armor can degrade when exposed to certain chemicals, moisture, or corrosive environments. This degradation can compromise the integrity of the cable's protective sheath and affect the safe operation of the electrical systems it powers. The material of the armor, typically aluminum or steel, can corrode, leading to potential exposure of the conductors and increasing the risk of electrical faults or failures.

Maintaining the structural and functional integrity of electrical installations is critical for ensuring safety and reliability; therefore, using Type MC cable in environments where it can be adversely affected by corrosive elements is inappropriate. Instead, alternative cable types that are specifically designed to withstand such conditions should be utilized.
