If a wire is installed so that it comes in contact with some moving parts, what protection should be given the wire?

When a wire is installed in proximity to moving parts, providing protection is crucial to ensure the safety and longevity of the electrical system. Passing the wire through conduit is the best option because conduit serves as a protective tube that shields the wire from damage caused by abrasion, friction, or impact from the moving parts. This safeguard helps maintain the integrity of the wire's insulation and keeps the electrical circuit safe from short circuits or other failures that could arise if the wire becomes damaged.

Using conduit also helps to avoid exposure to moisture, chemicals, and physical stresses, further enhancing the durability of the wiring. In applications with moving parts, a robust protective strategy, like conduit installation, mitigates risks and conforms to best practices and electrical codes, which mandate using conduits in certain applications for safety.
