What should be securely fastened in place during electrical installations?

During electrical installations, raceways must be securely fastened in place to ensure both safety and compliance with electrical codes. Raceways, which include conduits and other types of enclosures for electrical wiring, serve as protective pathways that help organize and safeguard conductors from physical damage and environmental effects. By securing raceways, the risk of mechanical impacts, accidental disconnections, or hazards from loose wiring is minimized.

Proper fastening of raceways also aids in maintaining the integrity of the electrical system, allowing for effective insulation and grounding, which are critical for preventing electrical hazards. Furthermore, securely installed raceways facilitate easier maintenance and upgrades since they provide a stable and organized path for the electrical systems.

The other components, such as conductors, circuit breakers, and switch boxes, also have their own installation requirements but primarily rely on raceways for protection and organization. Their proper installation is essential, but the question specifically highlights the importance of securely fastening raceways as a fundamental step in creating a safe electrical installation.
