Which type of conduit is typically used where high physical damage is expected?

Rigid Metal Conduit (RMC) is specifically designed to handle environments where there is a high likelihood of physical damage. This robust metal conduit system provides excellent protection against impact, abrasion, and other physical stresses, making it suitable for installations in industrial settings, exposed areas, or any location where heavy equipment might be present.

Its construction from heavy-duty steel or aluminum allows RMC to withstand significant forces that could otherwise damage less sturdy conduits. Also, because it is non-combustible, it can enhance safety in areas with fire hazards. The securing of RMC connections with threaded fittings adds to its durability, providing a secure and stable electrical pathway.

In contrast, other types of conduit like Schedule 40 PVC, while resistant to corrosion and lightweight, do not offer the same level of physical protection RMC provides. Flexible Non-Metallic Conduits are designed for less demanding situations where movement or vibrations are involved but do not provide the impact resistance of rigid metal options. EMT (Electrical Metallic Tubing) is lighter and easier to handle than RMC but lacks the same level of physical protection, making it less suitable for high-impact areas. Thus, Rigid Metal Conduit is the best choice for scenarios where high physical damage is a concern
