What must be true for a raceway according to NEC standards?

For a raceway to comply with NEC (National Electrical Code) standards, it must be securely fastened. This requirement is essential for ensuring the safety and stability of the electrical installation. Properly securing the raceway helps prevent movement that could lead to damage to electrical conductors or the raceway itself. It also minimizes the risk of physical hazards, such as the potential for falls or tripping, especially in environments where the raceway may be exposed to mechanical forces or environmental conditions.

Additionally, secure fastening supports the integrity of the overall electrical system by ensuring that the raceway remains in place over time, accommodating any changes in environmental conditions or usage without compromising safety. This is an important aspect of maintaining compliance with electrical safety standards and ensuring both functionality and durability in electrical installations.
