What is an advantage of nonmetallic cable compared to BX?

Nonmetallic cable, such as Romex, has the notable advantage of being suitable for both indoor and outdoor applications, depending on its specific type and rating. This versatility makes it appealing for contractors since it can be utilized in various settings without the need for different types of wiring for different environments. Nonmetallic cable is often weather-resistant and can withstand outdoor exposure when appropriately specified, which is beneficial for projects that require outdoor wiring solutions.

In contrast, BX (metal-clad cable) is primarily designed for indoor use and has limitations when it comes to exposure to the elements. The capability of nonmetallic cable to be used in various environmental conditions adds to its convenience and flexibility in residential and commercial construction projects.

Additionally, while nonmetallic cable can indeed come in different wire configurations and may connect to junction boxes, these attributes are not exclusive to it alone. Therefore, the primary distinguishing factor that highlights its advantage over BX in the given context is its adaptability for multiple environments.
