This 600 MCM 4-conductor Priority-Plex assembly with an integrated 2/0 Ground is a high-performance feeder solution for 277/480V 3-phase, 4-wire systems. By factory-twisting the heavy-gauge phases (Brown, Orange, Yellow), the neutral (Gray), and a 2/0 AWG Green ground, this system provides a complete circuit in a single bundle, maximizing labor efficiency and conduit space.

Why Choose Priority-Plex 600 MCM with 2/0 Ground?

Managing five individual large-gauge conductors through a single conduit is physically exhausting and prone to “jamming.” Priority-Plex technology eliminates these risks by providing a pre-twisted assembly that pulls as a single unit. The 2/0 ground is sized to meet standard NEC requirements for this ampacity, ensuring a safe ground path while significantly reducing the overall bundle diameter compared to a full-sized ground.

• Optimized Grounding: The 2/0 AWG Green ground is factory-integrated, ensuring a reliable low-impedance ground path while maintaining the most efficient bundle geometry for long industrial pulls.

• 480V Phase Identification: Permanent, factory-colored insulation (Brown, Orange, Yellow, Gray) provides instant phase identification for high-voltage systems, eliminating the labor and human error associated with field-taping.

• Reduced Site Footprint: Replaces a five-reel setup with one. This is critical in tight electrical rooms where staging multiple heavy jack stands is not feasible.

• Rugged XHHW-2 Insulation: The cross-linked polyethylene (XLPE) jacket is rated for 90C and provides superior moisture and chemical resistance, essential for industrial and underground environments.

Technical Note: Installing a 5-conductor 600 MCM bundle requires high-capacity pulling equipment. Ensure the conduit is sized correctly for a 5-wire (600/2/0) configuration per NEC Chapter 9. Always use AL9CU-rated mechanical or compression connectors and apply an approved antioxidant compound on all terminations to prevent oxidation.
