Which types of conduit can be used to support a luminaire (light fixture)?

When considering the types of conduit that can be used to support a luminaire, it's essential to focus on both structural integrity and compatibility with electrical codes. Rigid Metal Conduit (RMC) and Intermediate Metal Conduit (IMC) are designed to provide substantial mechanical support due to their robust construction. They can adequately bear the weight of light fixtures and provide protection against physical damage.

RMC, being a heavier gauge steel conduit, is often preferred for locations that require higher durability and strength. IMC, which is lighter than RMC but still strong, is also suitable for similar applications. Both types of conduit not only support the fixture but also ensure a safe and reliable electrical installation.

While other conduits such as EMT (Electrical Metallic Tubing) and PVC can be used in various applications, RMC and IMC are specifically appropriate for supporting luminaires because they meet structural and safety requirements in most electrical codes.
