What is the primary use of BX wiring in construction?

BX wiring, which refers to armored cable, is primarily used in construction for exposed electrical systems. This type of wiring is characterized by its metal sheath, which provides enhanced protection against physical damage and environmental factors. The armored protection makes BX wiring particularly suitable for areas where the wiring might be susceptible to impact or abrasion, such as in industrial settings or areas where the electrical systems are more exposed.

While BX wiring is safe for indoor and outdoor lighting, its distinctive armored feature is specifically designed to protect the wiring itself, making it ideal for applications where the wiring may not be concealed or where it could be accidentally exposed to harsher conditions. Grounding purposes are also a function of BX wiring due to its metal sheath, but its main role is to provide a robust conduit for electrical wiring that is accessible. Therefore, understanding BX wiring's primary purpose emphasizes its suitability for exposed applications in construction environments.
