According to the NEC, how often must Rigid Metal Conduit (RMC) be supported?

According to the National Electrical Code (NEC), Rigid Metal Conduit (RMC) must be supported at intervals not exceeding 10 feet. This requirement ensures that the conduit is secure and minimizes any potential hazards that could arise from sagging or bending, which could damage the conductors inside or result in an unsafe installation. Additionally, RMC should be securely fastened within 3 feet of any termination point, including fittings, to provide extra support and prevent movement. This standard helps maintain the integrity of the electrical installation and ensures compliance with safety regulations.
