What must raceways, cable assemblies, boxes, cabinets, and fittings be according to the National Electrical Code?

The requirement that raceways, cable assemblies, boxes, cabinets, and fittings must be securely fastened in place is fundamental for ensuring the safety and integrity of electrical installations. Secure fastening helps to prevent physical damage to the wiring systems and reduces the risk of electrical hazards such as short circuits or fires. When these components are properly secured, they maintain their intended pathways, helping to organize electrical systems and protect them from environmental factors, mechanical stresses, or human interaction.

In addition to physical safety, secure fastening also assists in meeting the code requirements for proper wiring, ensuring that installations are compliant with the NEC. This has implications for the overall performance and reliability of electrical systems in buildings. Keeping these elements firmly in place fosters a safe working environment and upholds the longevity of electrical installations.
