500 MCM 4C Twisted XHHW-2 Aluminum Feeder Cable, Priority-Plex®, (Brown, Orange, Yellow, Gray)

This 500 MCM 4-conductor Priority-Plex® assembly is a high-capacity industrial feeder solution designed for 277/480V 3-phase, 4-wire systems. By factory-twisting the Brown, Orange, Yellow, and Gray conductors into a single synchronized bundle, this system eliminates the need for on-site paralleling and dramatically reduces the complexity of heavy-gauge cable pulls.

Why Choose Priority-Plex® 500 MCM Aluminum Feeder?

Large-diameter cables like 500 MCM are notoriously difficult to manage when pulled individually. The Priority-Plex® twisting process ensures all four conductors maintain a consistent orientation throughout the conduit, preventing "jamming" and reducing the total pulling force required.

• Single-Reel Setup: Replaces the need for four separate reels and jack stands, saving significant floor space in tight electrical rooms and reducing equipment rental costs.

• 480V System Identification: The factory-colored conductors (Brown, Orange, Yellow, Gray) provide permanent color coding for high-voltage systems, removing the need for hand-taping and reducing the risk of phase-rotation errors.

• XHHW-2 Performance: Features cross-linked polyethylene (XLPE) insulation that is rated for 90°C in both wet and dry locations, offering superior protection against moisture and heat compared to standard PVC.

• Lightweight Efficiency: The AA-8000 aluminum alloy is significantly easier to handle and more cost-effective than copper alternatives of the same ampacity, which is crucial for large-scale commercial projects.

Common Applications

• Industrial Main Feeders: Supplying power from main switchgear to large 480V distribution panels and motor control centers (MCCs).

• Commercial High-Rise Services: Primary power distribution for hospitals, data centers, and office complexes.

• HVAC & Mechanical Systems: Powering large-scale chillers, boilers, and industrial-grade air handling units.

• Renewable Energy Infrastructure: Main collection lines for utility-scale solar arrays where 480V inversion is utilized.

Technical Note: Always verify conduit fill capacity. While the twisted configuration aids in the pull by reducing friction, the total cross-sectional area must still comply with NEC Chapter 9 requirements. Utilize AL9CU rated lugs and an approved antioxidant joint compound for all terminations to ensure a secure, cool-running connection.
