In the electrical industry, what does BX refer to?

BX refers to insulated wires that are enclosed in flexible metal tubing. This type of cable is commonly used in the electrical industry for branch circuit wiring. The metal tubing serves as both a protective conduit and a grounding mechanism, enhancing the safety of electrical installations. BX cables typically consist of insulated conductors housed within the metallic sheath, which helps to prevent damage from external factors such as physical impact and moisture.

The flexible nature of BX allows for easier installation in tight spaces or around corners, making it a popular choice for both residential and commercial electrical applications. The insulation of the wires within the metal tubing ensures that the conductors do not come into direct contact with the metal sheath, thus maintaining a safe operating environment.

In contrast to BX, options that refer to electrical panels, uninsulated electrical cables, or high-voltage wiring describe different aspects of electrical systems and do not accurately capture the specific meaning of BX in the context of insulated wires within flexible metal tubing.
