What role does a conduit hanger serve?

A conduit hanger plays a crucial role in supporting and securing conduit runs. Its primary function is to provide a stable and reliable connection for conduits, allowing them to be mounted to walls, ceilings, or other structures. This ensures that the conduit remains in place, protecting the electrical wiring inside from damage that can occur due to movement or external force. Conduit hangers also help in maintaining the proper alignment and spacing of the conduits, which is essential for effective installation and longevity.

The other options focus on functions that are not related to the primary purpose of conduit hangers. While insulation may protect against heat or moisture, and noise reduction might be important in specific scenarios, these are not the functions of conduit hangers. Similarly, covering exposed wire connections is a separate concern addressed by different components, such as junction boxes or wire nuts, rather than conduit hangers, which are specifically designed for support and securing.
