Step-by-step explanation:
Article 344 in the National Electrical Code (NEC) deals with rigid metal conduit (RMC) used for electrical wiring installations. RMC is a type of electrical conduit made from galvanized steel or aluminum, designed to provide protection to the electrical wiring inside it.
NEC Article 344 specifies the requirements for the installation, support, and use of RMC in various electrical systems. This includes guidelines on bending, threading, and securing the conduit, as well as requirements for grounding and bonding.
Some key requirements specified in NEC Article 344 include using RMC for exposed or concealed wiring in dry or wet locations, ensuring proper grounding and bonding, and following the guidelines for conduit installation based on the type of location and environmental conditions.
