How should raceways be configured before the installation of conductors?

The configuration of raceways before the installation of conductors should ideally be complete. This is important for several reasons. First, it ensures that all components of the raceway system, including fittings, junction boxes, and supports, are properly secured and connected. A complete installation minimizes the risk of obstructions or misalignments that could complicate pulling in the conductors.

Moreover, having a fully installed raceway system before conductors are added enhances safety during the installation process. It reduces the chances of damaging the raceway or the conductors themselves. A complete raceway allows for a streamlined installation and provides a reliable path for the electrical conductors, ensuring that they are protected from physical damage and environmental factors.

Testing for ground faults or maintaining partial completeness would not provide the same level of assurance regarding safety and functionality as having the raceway fully installed and ready for conductors.
