How must parallel conductors in a conduit run be set up?

In a conduit run, setting up parallel conductors with a ground conductor pulled through each conduit is crucial for ensuring safety and compliance with electrical codes. Each conduit not only serves to protect the live conductors but also needs to have a grounding path for fault conditions. This configuration helps to prevent electrical shock hazards and mitigates the risk of fire by providing a path for fault current in the event of an electrical fault, which directs the current safely to ground.

Without a ground conductor, the system may not be adequately protected, especially if there were to be an insulation failure or other faulty conditions that could expose equipment or individuals to hazardous voltages. Thus, the presence of a ground conductor in each conduit enhances the reliability of the safety features of the electrical system if multiple conductors are run in parallel.
