What is the defining feature of Rigid Metal Conduit (RMC) concerning its installation?

Rigid Metal Conduit (RMC) is designed to provide a robust and protective pathway for electrical wiring. The defining feature regarding its installation is that it can indeed be buried, provided that it complies with the guidelines set forth by the National Electrical Code (NEC). The NEC specifies requirements for the installation depth and protection of RMC when it is installed underground, ensuring safety and durability. This allows RMC to be used in various applications, both above and below ground, making it versatile for different installation environments. By following the NEC guidelines, technicians ensure that the conduit remains safe, functional, and effective in protecting electrical conductors.
