600 MCM 4C w/ 400 MCM Ground Twisted XHHW-2 Aluminum Feeder Cable, Priority-Plex®, (Brown, Orange, Yellow, Gray, Green)

This 600 MCM 4-conductor Priority-Plex® assembly with an integrated 400 MCM Ground is a high-capacity power distribution solution for 277/480V 3-phase, 4-wire systems. By factory-twisting the phase conductors (Brown, Orange, Yellow), the neutral (Gray), and a 400 MCM Green ground, this system provides a ready-to-install circuit that eliminates the immense physical effort of managing five individual heavy-gauge wires on-site.

Why Choose Priority-Plex® 600 MCM with 400 MCM Ground?

Handling 600 MCM conductors is notoriously labor-intensive. Priority-Plex® technology pre-twists the conductors into a single, synchronized bundle, ensuring they maintain their relative positions throughout the conduit. This prevents individual wires from "crossing over" or "wedging," which is the primary cause of cable jams and high pulling tension in large-diameter industrial conduits.

• Optimized Safety Ground: The 400 MCM Green ground is factory-integrated to provide a robust, low-impedance ground-fault path, sized specifically to meet or exceed code requirements for high-amperage industrial feeders.

• Streamlined Site Logistics: One reel contains the full circuit, replacing a five-reel setup. This dramatically reduces the job site footprint and the time required for set-up and staging.

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

• Rugged XHHW-2 Insulation: The cross-linked polyethylene (XLPE) jacket is tougher than standard PVC, offering superior resistance to physical stresses during heavy pulls and a 90°C rating in both wet and dry locations.

Common Applications

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

• Hospital Infrastructure: Providing reliable, high-capacity power for critical mechanical systems and backup power distribution.

• Data Centers: High-amperage 480V distribution from main switchgear to secondary transformers or large-scale UPS systems.

• Central Utilities: Ideal for powering industrial-scale chillers, boilers, and large water treatment pumping stations.

Technical Note: Installing a 5-conductor 600/400 MCM bundle requires high-capacity pulling equipment. Ensure that the conduit is sized correctly for the diameter of this specific assembly per NEC Chapter 9. Terminations must be made with AL9CU-rated mechanical or compression connectors, and an approved antioxidant compound should be applied to prevent oxidation.
