This 2/0 AWG 4-conductor Priority-Plex® assembly with an integrated #4 AWG Ground is a versatile, high-efficiency feeder solution for 277/480V 3-phase, 4-wire systems. By factory-twisting the phases (Brown, Orange, Yellow), the neutral (Gray), and a #4 AWG Green ground, this cable provides a complete "ready-to-pull" circuit that significantly reduces installation labor and job site waste.
Why Choose Priority-Plex® 2/0 AWG with #4 Ground?
At the 2/0 gauge, aluminum conductors are flexible but can still become a tangled mess when pulled as individual strands from multiple reels. Priority-Plex® technology eliminates "spiraling" and uneven tension. The twisted geometry ensures that the entire bundle moves as a single unit, which lowers the coefficient of friction and helps prevent insulation damage during tight turns in the conduit run.
Optimized Grounding: The #4 AWG Green ground is factory-integrated and sized to meet NEC requirements for standard 2/0 aluminum circuits, providing a safe and reliable low-impedance ground path.
Rapid Installation: One reel replaces five. This reduces setup time, requires fewer jack stands, and allows a smaller crew to manage commercial or industrial pulls with ease.
480V Phase Identification: Permanent, factory-colored insulation (Brown, Orange, Yellow, Gray, Green) provides instant identification. This removes the labor of field-taping and minimizes the risk of phase-rotation or grounding errors.
Rugged XHHW-2 Performance: The XLPE (Cross-linked Polyethylene) insulation is tougher than standard PVC, offering high resistance to moisture and heat (rated 90°C), which is essential for long-term reliability in industrial feeders.

Common Applications
Commercial 480V Sub-Feeders: Supplying power from main switchboards to secondary distribution panels in retail and office environments.
Industrial Equipment Feeds: Powering 3-phase machinery and small-to-medium motor loads in manufacturing plants.
Healthcare & Institutional: Reliable power distribution for hospital mechanical wings and university laboratory buildings.
EV Charging: Serving as the primary supply for Level 2 or Level 3 charging infrastructure in commercial parking lots.
Technical Note: When terminating 2/0 aluminum, always use AL9CU-rated mechanical or compression connectors. It is critical to wire-brush the conductor and apply an approved antioxidant joint compound to ensure long-term connection integrity. Always verify that your conduit sizing accommodates the 5-conductor twisted bundle per NEC Chapter 9 requirements.
