How often should EMT be secured and supported?

Securing and supporting electrical equipment, including EMT (Electrical Metallic Tubing), is essential for safety and compliance with electrical codes. The National Electrical Code (NEC) stipulates that EMT should be secured at intervals no greater than 10 feet. This ensures that the conduit remains stable, provides protection for the wires inside, and minimizes the risk of damage or disconnection due to movement or external forces. Proper securing prevents sagging, misalignment, and helps maintain the integrity of the system over time. Hence, the correct answer reflects the NEC guideline that allows for safe and effective installation practices when working with EMT.
