MC Cable: A Reliable Choice for Commercial and Industrial Wiring
MC cable (short for Metal Clad Cable) is a trusted wiring solution for a wide range of applications, from commercial buildings and healthcare facilities to industrial environments and theaters. Known for its superior performance and flexibility, MC cable combines durable metal clad protection with the versatility needed for both indoor and outdoor use.
Metal Clad Cable: Built for Demanding Environments
Metal clad cable features a protective aluminum interlocked armor or interlocked aluminum armor surrounding insulated conductors. This construction makes it ideal for use in wet locations, direct burial, and exposed installations in cable trays or corrugated metal sheath systems.
Its ability to withstand fire, moisture, and mechanical damage makes metal clad cable the preferred option in demanding environments, especially where grounding and durability are critical.
Insulated Conductors: Safety and Versatility
Inside the metal clad armor, you'll find insulated conductors—typically copper or 10 AWG aluminum—sheathed in thermoplastic or PVC materials. These conductors are engineered for efficient power delivery and are available in multiple sizes and classes, depending on your application.
Type MC cable is designed to handle branch circuits, feeders, and service entrance wiring with confidence.
Metal Clad: Approved for a Variety of Installations
According to the NEC (National Electrical Code), MC cable is suitable for:
Exposed or concealed work
Cable trays
Job site installation
Factory and industrial assembly use
Healthcare and commercial settings
It’s often chosen for its time-saving installation, which reduces labor and materials cost while maintaining code compliance. Electricians and installers appreciate its interlocking metal tape armor that resists crushing and makes installation smoother.
Type MC: Code-Compliant and Versatile
Type MC cable is UL listed and meets all applicable NEC standards for commercial and industrial wiring. Its interlocked armor eliminates the need for separate conduit in many applications, especially in indoor settings where fire resistance, space constraints, and flexibility are important.
10 AWG MC Cable: Common Applications
10 AWG is one of the most common sizes for MC cable, offering a balance of strength and flexibility. It is typically used in:
Branch circuits for lighting and receptacles
Small motor circuits
Wiring in theaters, retail stores, and commercial kitchens
HVAC equipment and feeder installations
Available in multiple lengths (often sold by the feet), this wire size supports dependable operation and is easy to route in tight spaces.

Frequently Asked Questions
What is MC cable used for?
MC cable (Metal Clad Cable) is used for wiring in commercial, industrial, and healthcare facilities. It’s ideal for power distribution, branch circuits, and feeder installations in both indoor and outdoor environments. It’s especially valued in demanding environments due to its durability and fire resistance.
What makes MC cable different from other wiring methods?
MC cable features interlocked aluminum armor or metal clad protection around insulated conductors, which eliminates the need for additional conduit in many applications. Its flexibility, superior performance, and code compliance (including NEC approval) make it a top choice for professional electricians and installers.
Can MC cable be used in wet locations or direct burial?
Yes. Certain types of MC cable are rated for wet locations and direct burial, especially when the cable has a PVC jacket or corrosion-resistant coating. Always check the product specifications and NEC requirements to ensure it is suitable for the intended application.
What sizes does MC cable come in?
MC cable is available in a wide range of AWG sizes, including 10 AWG, which is commonly used for lighting circuits and small motor loads. The cable also comes in different conductor counts and lengths to meet specific installation needs.
Is MC cable suitable for use in cable trays?
Yes. MC cable is frequently installed in cable trays, especially in commercial and industrial buildings where efficient installation and clean cable management are priorities. Its interlocking metal tape design adds extra protection and supports long-term performance in high-traffic areas.
