How should conduit be properly supported?

The proper support of conduit is crucial for ensuring safety and functionality in electrical installations. The National Electrical Code (NEC) sets specific guidelines regarding the intervals at which conduit must be supported to prevent sagging, damage, and electrical hazards. Typically, rigid conduit must be supported every 10 feet, while flexible conduit requires support at intervals of 5 feet. This ensures that the conduit remains stable and is less likely to sustain mechanical stress or strain over time.

Following these NEC guidelines helps maintain the integrity of the electrical system, reduces the risk of physical damage to the conduit, and allows for ease of inspections and maintenance. Therefore, adhering to these support intervals is essential for all types of conduit installations. Proper support also helps in complying with local code requirements, ensuring that the installation is safe and up to standard.
