400 MCM 3C w/ Ground Twisted XHHW-2 Aluminum Feeder Cable, Priority-Plex, (Brown, Orange, Yellow, Green)

This 400 MCM 3-conductor Priority-Plex assembly is a versatile power distribution solution designed for high-capacity industrial and commercial feeders. Featuring aluminum XHHW-2 insulated conductors and a dedicated grounding conductor, this factory-twisted configuration is engineered to streamline installations in conduit by eliminating the traditional labor-intensive process of pulling individual wires.

Why Choose Priority-Plex 400 MCM Aluminum Feeder?

Priority-Plex technology eliminates the need to set up and synchronize multiple reels on a job site. By twisting the Phase conductors (Brown, Orange, Yellow) and the Grounding conductor (Green) together at the factory, the entire circuit pulls as a single unit. This prevents conductors from crossing over or “wedging” inside the conduit, which is a common cause of insulation damage during difficult pulls.

• Optimized Labor Costs: Single-reel setup reduces the number of personnel required for a pull and significantly cuts down on preparation time.

• XHHW-2 Insulation: Each conductor features cross-linked polyethylene (XLPE) insulation, providing superior heat resistance, moisture protection, and high dielectric strength.

• AA-8000 Aluminum Alloy: Utilizing lightweight 8000 series aluminum provides a cost-effective alternative to copper, reducing the total weight of the pull and the tension on pulling equipment.

• System Identification: Pre-colored conductors for 480V systems (Brown, Orange, Yellow) ensure easy phase identification, with a dedicated Green conductor for equipment grounding.

• Thermal Performance: Fully rated for 90C continuous operation in both wet and dry locations.

• Reduced Friction: The twisted geometry reduces the total surface area in contact with the conduit wall, lowering the coefficient of friction and making long-distance pulls easier.
