300-4 MC Cable Applications:

Aluminum MC cable, or aluminum metal clad cable, is an electrical wire used under high ambient temperature in power distribution, particularly in feeder, branch, and service ones, in diverse purpose buildings. The MC cable is also used for diverse circuits, such as control, signal, power, and lighting ones, as well as this electrical cable is used for installations, air-handling spaces, places of assembly, aerial applications, cable tray and raceways, IT equipment, and hazardous locations.

Common Applications:

• Commercial Installations
• Multi-Unit Residential Buildings
• Industrial Settings
• Branch, Feeders, and Service Power Distribution
• Power, Lighting, Control, and Signal Circuits
• Places of Assembly
• Cable Tray Installations
• Aerial Installations with Support

Specific Applications of 300-4 MC:

• Industrial Facilities (larger machinery and equipment) 
• Large Commercial Buildings for power distribution
• Data Centers (server racks and other critical components)
• Utility Connections
• Backup Power Systems
• Renewable Solar and Wind Energy Installations
• Elevators and Large Motors
• HVAC Systems

300-4 MC Cable Standards: 

• UL 44, UL 1569 for type MC 
• ICEA S – 95-658 
• NEMA WC70 
• Federal Spec A-A59544 (formerly J – C – 30B) 
• IEEEE 1202 70,000 BTU vertical flame test

300-4 MC Cable Construction

Conductors:

MC wires conductor is an 8000 series aluminum conductor. These conductors are also light, soft, and flexible, hence easy to work with, especially during installation.

Insulation:

The aluminum clad wire has a color-coded cross-linked polyethylene (XLP) insulation, which improves the service life of the cable. XLP is resistant to abrasion, heat, corrosive chemicals, moisture, and sunlight, making the cable withstand the punishing outdoor conditions. Due to color coding, it is easily identifiable and non-conducting, which keeps the user safe from shocks.

Armor:

The armor of the MC feeder cable is an overall aluminum interlocked armor.
