900 MCM 4C w/ 900 MCM Ground Twisted XHHW-2 Aluminum Feeder Cable, Priority-Plex, (Brown, Orange, Yellow, Gray, Green)

This 900 MCM 4-conductor Priority-Plex assembly with an integrated 900 MCM Ground is the pinnacle of high-amperage solutions for 277/480V 3-phase, 4-wire systems. By factory-twisting five massive conductorsBrown, Orange, Yellow, Gray, and a 900 MCM Green groundthis system handles the most extreme electrical loads of industrial infrastructure while simplifying an otherwise massive installation task.

Why Choose Priority-Plex 900 MCM Aluminum?

At the 900 MCM scale, cable weight and physical stiffness are the primary obstacles. Priority-Plex technology pre-twists the entire circuit into a single, synchronized bundle. This prevents the conductors from “wedging” or “crossing” in large conduits and ensures that pulling tension is distributed equally across the entire assembly.

• Full-Sized Ground Support: The inclusion of a 900 MCM Green ground within the twisted bundle ensures maximum safety and a reliable low-impedance path for ground-fault current in massive industrial circuits.

• 480V System Integrity: The factory-colored conductors (Brown, Orange, Yellow, Gray) provide permanent phase identification. This eliminates the massive labor requirement of hand-taping 900 MCM wire and virtually removes the risk of high-voltage cross-wiring.

• Maximum Pull Efficiency: The twisted configuration reduces the surface contact area with the conduit, lowering friction and allowing for longer, smoother pulls through heavy-duty industrial sweeps.

• XHHW-2 Performance: The XLPE insulation provides superior heat resistance and a low coefficient of friction, which is essential for protecting the integrity of the conductor during high-force pulls.

Technical Note: Pulling a 5-conductor 900 MCM twisted bundle requires specialized heavy-duty tuggers and high-capacity pulling eyes. Ensure that all terminations are made with AL9CU-rated connectors and that an approved antioxidant compound is used. Always verify that the conduit size and support structures are engineered to handle the substantial weight of this assembly.
