3/0-4C w/ Ground Twisted XHHW-2 Aluminum Feeder Cable, Priority-Plex®, (Brown, Orange, Yellow, Gray, Green)

This 3/0 AWG 4-conductor Priority-Plex® assembly with an integrated #4 AWG Ground is a compact, 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® 3/0 AWG with #4 Ground?

At the 3/0 gauge, aluminum conductors are agile but can still be difficult to manage when pulled as individual strands. Priority-Plex® technology eliminates the "nesting" or "tangling" that occurs with loose wires. 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 3/0 aluminum circuits, providing a safe and reliable low-impedance ground path.

• Streamlined Site Logistics: One reel contains the full circuit. This eliminates the need for a five-reel setup, reducing the physical footprint in the electrical room and requiring fewer personnel to manage the pull.

• 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.

• HVAC Infrastructure: Providing the main feed for roof-top units (RTUs) and large commercial air handlers.

Technical Note: When terminating 3/0 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.
