14/4 Solid Metal Clad MC Copper Conductor W/G 600V Aluminum Armored Cable

14/4 Solid Metal Clad MC Copper Conductor W/G – 600V Aluminum Armored Cable

Description

The 14/4 MC cable is an electrical wire designed for power distribution up to 600 volts. Rated for 90°C in dry locations, it is commonly used for branch circuits, feeders, and service entrances.

Its aluminum interlocking armor provides mechanical protection, eliminating the need for conduit. The green insulated grounding conductor enhances safety, while its lightweight design reduces labor costs, making it a cost-effective alternative to piped wire installations.

Applications

The 14/4 Solid MC cable is commonly used in residential, commercial, and light industrial applications, including:

• Multi-Way Switching Circuits: Ideal for three-way and four-way switching, allowing multiple switches to control a single light.
• HVAC and Control Wiring: Used in heating, ventilation, and air conditioning systems for power and control functions.
• Dedicated Circuits for Motors and Pumps: Suitable for wiring small motors, pumps, and industrial equipment requiring separate conductors.
• Lighting and Power Distribution: Common in offices, retail stores, and multi-unit residential buildings.
• Cable Tray and Raceway Installations: Approved for cable tray and conduit installations per NEC®.
• Under Raised Floors: Ideal for data centers and office environments, ensuring organized and protected wiring.
• Fire-Rated Installations: Compliant with UL 1, 2, and 3-hour fire-rated through-penetration assemblies.

Construction

Conductors

The 14/4 MC cable consists of solid copper conductors, providing reliable and stable connections for fixed installations.

Conductor Insulation

THHN/THWN insulation ensures moisture, heat, and chemical resistance, making it suitable for wet and dry locations. The 90°C dry / 75°C wet rating ensures durability.

Armor

The aluminum interlocking strip armor protects against crushing and rodent damage, while polypropylene tape reinforces insulation.
