중간 금속 도관(IMC): IMC is similar to RMC but with a thinner wall, making it lighter and easier to handle while still providing robust protection. It is made of galvanized steel or aluminum.
전기 금속 튜브(EMT): EMT is a thinner-walled, lightweight metallic conduit made from galvanized steel. It is also known as “thin-wall conduit” and is easy to bend, making it a popular choice for electrical wiring installations in residential and commercial buildings.
유연 금속 도관(FMC): FMC is a flexible, spiral-wound metal conduit that allows for easy installation in areas requiring movement or frequent adjustments. It is typically made from steel and can be used to route wiring through tight spaces.
Liquid-tight Flexible Metal Conduit (LFMC): LFMC is a flexible conduit that combines the benefits of flexibility with additional protection from moisture and liquids. It consists of a metal tube with a non-metallic inner coating to make it watertight.
Non-Metallic Conduit
Non-metallic conduit, as the name suggests, is made from non-metallic materials, most commonly PVC. These conduits are more lightweight, easy to install, and highly resistant to corrosion, making them a popular choice for many residential and commercial installations.
Polyvinyl Chloride (PVC) Conduit: PVC electrical conduit is one of the most widely used types of non-metallic conduit. It is resistant to moisture, corrosion, and impacts, making it an excellent choice for both indoor and outdoor installations.
High-Density Polyethylene (HDPE) Conduit: HDPE conduit is made from a tough, flexible plastic that is ideal for use in underground installations. It is highly resistant to corrosion, abrasion, and chemicals.
Electrical Nonmetallic Tubing (ENT): ENT conduit is a flexible, non-metallic tubing commonly used in indoor environments, such as residential and commercial buildings, where flexibility and ease of installation are key considerations.
Liquid-tight Flexible Nonmetallic Conduit (LFNC): LFNC is a flexible, non-metallic conduit designed to protect wires from moisture, chemicals, and other environmental hazards. It consists of a spiral wound plastic core with an outer jacket for additional protection.

Many non-metallic conduits, like ENT and LFNC, are flexible, offering easy installation in areas that require frequent bending or movement. These are often preferred in residential and commercial environments due to their ease of use.
- Corrosion and Impact Resistance
- Metallic conduits generally offer high resistance to physical damage and can withstand significant impact. However, they can be prone to corrosion unless galvanized or coated. RMC and IMC are often used in outdoor or industrial settings where the conduit may be exposed to moisture, chemicals, or extreme conditions.
- Non-metallic conduits are naturally resistant to corrosion, making them ideal for environments where moisture or chemicals are a concern. PVC and HDPE are corrosion-resistant and do not need special coatings like metallic conduits. However, non-metallic conduits like PVC tend to be more susceptible to impact damage, especially when compared to rigid metallic options.
- Grounding Capabilities
- Metallic conduits, particularly RMC and IMC, provide natural grounding for electrical systems due to their conductive properties. EMT requires grounding through bonding, making the installation a bit more complex.
- Non-metallic conduits do not conduct electricity and therefore cannot provide grounding by themselves. If grounding is necessary, additional grounding conductors or bonding conductors must be installed within the conduit.
- Cost Considerations
- Metallic conduits are typically more expensive, particularly in the case of RMC, IMC, and LFMC. The higher material cost is also compounded by the need for specialized tools to install rigid metallic conduit.
- Non-metallic conduits, especially PVC, are generally much more affordable. They are cost-effective for large-scale installations, particularly in residential and light commercial projects.
- Temperature Resistance
- Metallic conduits are generally more temperature-resistant and can handle extreme heat and cold better than non-metallic types. This makes them ideal for applications in areas that experience high heat or sub-zero temperatures.
- Non-metallic conduits such as PVC and ENT have a more limited temperature range and may degrade under high heat or cold, though HDPE performs better in colder climates.
- Fire Resistance
- Metallic conduits inherently have better fire-resistance due to the nature of the materials used (steel, aluminum), offering additional protection against fire hazards.
- Non-metallic conduits, particularly PVC, have a flammability rating. While PVC is flame retardant, it can still catch fire under extreme conditions and may release toxic fumes if ignited.
- Moisture Resistance
- Metallic conduits like LFMC and RMC are effective at sealing out moisture, making them suitable for wet or humid environments, although some metallic types need additional treatments or coatings to enhance water resistance.
- Non-metallic conduits such as PVC and HDPE provide excellent moisture resistance and are commonly used in underground and outdoor applications. LFNC is another non-metallic option that offers good moisture protection.
