Different Types of Electrical Conduit

In any electrical project, the selection of the right electrical conduit is an important step toward ensuring safety, durability, and compliance with local codes. Conduits are more than just protective tubing, they protect electrical wiring from physical damage, moisture, and other environmental hazards. Whether you are designing a residential, commercial, or industrial project, understanding the numerous types of electrical conduits will help you make important decisions

Types of Electrical Conduits

Electrical conduits are made from different materials, each for particular requirements of the installation environment. If you want to know what types of electrical conduit will suit your projects, consider getting electrical material takeoff to achieve better cost and material projections so that the process will be even more streamlined and cost-efficient.

Some of the most widely used types of electrical conduits are:

Rigid Metal Conduit

Rigid Metal Conduit. It’s also very strong and safe. Its composition is either steel or aluminum. Conduits offer an excellent resistant degree towards impacts, moisture or fires in their extreme condition towards adverse surroundings. This can, therefore, be said of its use as heavy-duty hence a more applicable industrial and underground installation for outdoor systems it can be used for maximum protection purpose.

Application

RMC installation cuts and threads the conduit for the available spaces. Its use is primarily for those places where the conduit needs exposure or underground and offers physical protection to wiring from extreme conditions.

Advantages

Impact Resistance: RMCs from heavy-duty steel or aluminum can protect wiring against any form of impact damage.

Corrosion Resistance: Suitable for areas with high moisture or substances causing corrosion

Fire Resistance: It is fire-resistant, especially when applied to industrial settings.

Durability: Suitable for long-term installations under challenging conditions above and below ground

While RCM is heavier and more expensive than other conduit types, its long-term reliability makes it a shrewd investment for critical installations. Electrical estimating services can outsource the calculations of the precise material requirements and labor costs for RMC to contractors, ensuring optimal material usage and minimizing waste.

Intermediate Metal Conduit

This is the lighter version of RMC. It is perfect with strength and cost-effectiveness. This product is made using galvanized steel, offering a middle point between strength and weight. In terms of flexibility and rugged protection, it is apt for commercial and industrial applications. It has a wide range of applications, so it can be used in different aspects.

Application

IMC is easier to install compared to RMC because it is lighter and is commonly used in residential, commercial, and light industrial projects both indoors and outdoors. It is suitable for many types of installations because of its adaptability.

Benefits

Lightweight Construction: It is easier to handle and install, thereby reducing labor costs.

Corrosion Resistance: Galvanized steel provides corrosion resistance, perfect for outdoor and industrial environments.

Strength: It provides the same strength and RMC protection but with less weight.

Cost-Effective: It provides the same level of protection as RMC but at a much cheaper cost.

Electrical Metallic Tubing

Commonly known as thin-wall conduct, electrical metallic tubing is a lightweight, economical conduit of galvanized steel. It is extensively used to protect electrical wiring in residential and commercial applications where an essential high-impact resistance is not required.

Application 

The application of installation is relatively simple, with hacksaw cutting and bender used for forming. It is often used in dry environments like offices or homes, where there is minimal risk of physical damage.

Benefits

Lightweight and Easy to Install: EMT wire weighs very little, and installing the same is also quite easy. Thus, both residential and commercial wiring can be undertaken with this wire.

Economic: As compared to RMC and IMC, the cost of EMT is lower without losing the basic protection.

Flexible for Various Installments: This can be used for wire installation in walls, floors, or ceilings with lesser trouble.

Corrosion Resistance: The galvanized coating protects against mild corrosion, suitable for dry interior spaces. 

Flexible Metal Conduit

A flexible metal conduit is a spiral-wound metal conduit what offers flexibility for installation in tight spaces or areas requiring frequent adjustments. It is generally used when a rigid conduit is not feasible.

Application

FMC can be bent easily and installed within small spaces where rigid conduits will be too bothersome to apply.  It is often used to connect electrical systems to machines or appliances that need to move.

Advantages

Flexibility: BeBentnd adjusted to pass through narrow passes or around obstacles.

Relatively Fast and Simple Installation: Applicable for short-term designs or whenever changes are highly required. It’s flexible, so perfect for connecting machines, appliances, or other moving equipment to power.

Protection from Water Vapor and Chemicals: Provides good protection against water vapors and chemicals.  

Non-Metallic Conduct

Non-metallic conduits, particularly PVC (Polyvinyl Chloride) are lightweight, noncorrosive conduits employed to safeguard wiring in diverse environments. PVC is water-resistant and resistant to ultraviolet light hence is appropriate for indoor as well as outdoor use.

Application 

PVC conduit is rather easy to cut and connect with the aid of solvent cement. This one is widely used in exterior installations and subterranean cabling where corrosion can become a problem.

Advantages

Corrosion Resistant: Suitable for applications with exposure to moisture, chemicals, or outdoor environment

Cost-Effective: PVC conduit is less expensive and hence used by many for residential and commercial wiring.

UV Resistant: The resistance to UV makes it perfect for outdoor applications without the possibility of degradation due to sunlight.

Liquid Tight Flexible Metal Conduit

Liquid tight Flexible Metal Conduit (LFMC) is the flexibility of FMC combined with a waterproof, weather-resistant jacket that protects against water and moisture. It has special applications in wet-condition environments.

Application

Liquid tight flexible metal conduit protects wiring in outdoor or industrial applications where moisture is a concern. It is flexible and can easily be routed around corners and other obstacles.

Benefits

Waterproof: This is the best feature against water exposure, perfect for outdoor or industrial applications.

Corrosion Resistant: The protective outer jacket helps prevent corrosion and increase the conduit’s life cycle.

Flexible and Easy to Install: This will enable easy routing in confined spaces and around obstacles.

Weatherproof: This is ideal for marine or harsh environmental conditions where wiring needs protection from moisture and dust.

Cost Control: electrical estimating services make sure the contractors are better prepared for the LFNC; they do not take time or increase their operation costs by having the appropriate amount needed.

PVC-Coated Conduit

This is an assembling of galvanized steel and aluminum with PVC coating in addition to more protection on the environment. This is, therefore, applied where both protection needs must avoid physical attacks and corrosion attacks.

Application 

PVC-Coated conduit is to be used where the conduit will experience chemical or moisture exposure. It is applied similarly to RMC but with some extra protection against the atmosphere.

Benefits 

Corrosion Resistance: As the PVC coating covers up the steel or aluminum, it provides a good resistance for the corrosive elements such as marine or chemical applications.

Durability Protects a long term, even in extreme weather.

Versatile: To be used indoor and outdoors, especially in industrial or commercial areas

Physical protection: Excellent protection against physical damage, which is best suited for spaces with more traffic or lots of equipment.

Aluminum Conduit

Aluminum Conduit is lighter and resistant to rust, it is used for installing outdoors. It is adopted due to weight issues,

Application 

Aluminum conduit is significantly used when the application needs weight reduction. It could be bent easily for installation, and it suits itself to exposed installations.
