Why Choose Metal-Clad Armored Cable Over Electrical Conduit?

Metal-clad (MC) armored cable constructions are a cost-effective alternative to conduit. These high-performing solutions offer significant cost savings by eliminating the need for electrical conduit and the labor required for installation.

HOW TO SAVE WITH FEEDER MC

Contractors who use Type MC armored cable report 50-70% combined labor and material savings versus traditional pipe and wire. ?

Benefits of Armored Cable

• Eliminates the need for electrical conduit
• Provides higher mechanical protection and durability
• Requires fewer labor hours during installation

Contractors can easily identify opportunities for armored cable because it can be used in any application where typical pipe and wire is installed. This includes industrial, utility, and commercial projects. ?

Feeder MC is primarily used in commercial construction, while jacketed MC is widely used in industrial applications. It is permitted for indoor or outdoor service, feeder, or branch circuits and can be exposed or concealed.

COST-SAVING ALTERNATIVE TO PIPE & WIRE

Metal-clad (MC) armored cable constructions are a cost-effective alternative to conduit. These high-performing solutions offer significant cost savings by eliminating the need for electrical conduit and the labor required for installation. Contractors who use armored cable require limited pulling equipment, fewer reels, no specialty cutting or bending tools, and less time setting up pulls.

ADVANTAGES OF ARMORED CABLE

• Armored cables provide the protection and durability required without the need for electrical conduit, elbows, costly offsets, and conduit couplings.
• Metal-clad armor resists corrosion, making it suitable for areas exposed to moisture.
• Interlocked armor is flexible, unlike conduit or even continuously welded?armor, ensuring damage will not affect inner conductors. It is also more easily installed where complex, close-spaced bends would be difficult for conduit.
• No specialty cutting or bending tools are needed for installation.

These advantages can mean significant savings in material and labor costs.

Application Considerations

When deciding between metal-clad armored cable and electrical conduit, it is crucial to consider the specific requirements of the application.

• Indoor vs. Outdoor: MC cable is primarily designed for indoor use, while electrical conduit is suitable for both indoor and outdoor applications. If the installation is exposed to moisture, extreme temperatures, or corrosive environments, electrical conduit may be a better choice to ensure long-term durability.
• Code Compliance: Different regions and jurisdictions may have specific electrical codes and regulations governing the use of MC cable and electrical conduit. It is essential to consult local codes and standards to ensure compliance with the applicable requirements.
• Flexibility Requirements: If the installation requires a high degree of flexibility and maneuverability, MC cable's inherent flexibility may be advantageous. However, if the installation involves long runs or rigid structural elements, electrical conduit may provide better support and protection.
• Future Modifications: Consider the potential need for future modifications or additions to the electrical system. MC cable allows for easier modifications and upgrades as individual conductors can be easily accessed and replaced. Electrical conduit may require more extensive work to accommodate changes.
• Specific Industry Requirements: Certain industries, such as healthcare or hazardous locations, may have specific requirements for electrical wiring systems. In such cases, electrical conduit may be necessary to meet the specialized demands of the industry.

Conclusion

Choosing between metal-clad armored cable and electrical conduit requires careful consideration of various factors, including ease of installation, physical protection, flexibility, cost considerations, and application-specific requirements. Metal-clad armored cable offers advantages in terms of ease of installation, flexibility, and cost-effectiveness. It provides excellent physical protection and grounding while reducing labor and material costs. Electrical conduit, on the other hand, offers robust protection in extreme conditions and may be more suitable for outdoor installations or specialized applications.

Ultimately, the decision between metal-clad armored cable and electrical conduit depends on the specific needs of the project, local codes and regulations, and the desired balance between ease of installation, physical protection, and cost considerations. Consulting with electrical professionals and considering the unique requirements of the application will ensure a well-informed decision that meets both functional and regulatory requirements.
