In which situation should Type MC cable not be utilized?

Type MC cable is typically utilized in many applications due to its flexibility and ease of installation. However, it is specifically not recommended for use in corrosive environments. This is because Type MC cable, while providing some level of protection with its metal sheath, may not be suitable for areas where the presence of corrosive substances can degrade the integrity of the materials over time. Such environments might include areas exposed to chemicals, salts, or severe humidity, all of which can undermine the protective qualities of the cable and ultimately lead to failure.

In other scenarios, like areas subject to physical damage, below-grade applications, and high-temperature situations, while precautions and additional protective measures—like conduit or appropriate fittings—might be necessary, Type MC cable can still be used with certain limitations and proper installation methods. Thus, the recognition of corrosive environments as unsuitable for Type MC cable emphasizes the need for selecting the right type of cable for specific environmental conditions to ensure safety and reliability.
