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

This 250 MCM 4-conductor Priority-Plex® assembly with an integrated #1 AWG Ground is a streamlined feeder solution designed for 277/480V 3-phase, 4-wire systems. By factory-twisting the phase conductors (Brown, Orange, Yellow), the neutral (Gray), and a #1 AWG Green ground into a single synchronized bundle, this cable eliminates the need for managing five separate reels and provides a "ready-to-pull" circuit for high-efficiency installations.

Why Choose Priority-Plex® 250 MCM with #1 Ground?

At 250 MCM, conductors are often stiff and prone to "spiraling" or "bird-caging" during parallel pulls. Priority-Plex® technology maintains a consistent bundle geometry, which significantly reduces the coefficient of friction within the conduit and prevents cables from "wedging" in 90° bends.

• Optimized Grounding: The #1 AWG Green ground is factory-integrated and sized to meet NEC requirements for standard 480V circuits, providing a safe low-impedance ground path while maintaining a compact overall bundle diameter.

• 480V Phase Identification: Permanent, factory-colored insulation (Brown, Orange, Yellow, Gray, Green) provides instant phase identification. This removes the labor-intensive requirement for field-taping and reduces the risk of phase-rotation or grounding errors.

• Rapid Installation: One reel replaces five. This reduces setup time, requires fewer jack stands, and allows a smaller crew to manage large-scale commercial or industrial pulls.

• XHHW-2 Durability: The cross-linked polyethylene (XLPE) insulation is rugged and moisture-resistant, offering a higher melting point and superior protection during high-tension pulls compared to PVC-based insulation.

Technical Note: When terminating 250 MCM aluminum, always use AL9CU-rated mechanical or compression connectors. It is vital to wire-brush the conductor and apply an approved antioxidant joint compound to ensure long-term connection integrity and prevent surface oxidation. Always verify that the conduit size is adequate for a 5-conductor twisted bundle per NEC Chapter 9.
