Specifically engineered for medium-to-high amperage 480V systems, this 1/0 AWG Priority-Plex® twisted assembly is a powerhouse of installation efficiency. By factory-twisting three phase conductors into a cohesive bundle, this cable removes the logistical complexity of managing multiple reels and the physical strain of manual wire paralleling, ensuring a cleaner, faster, and more cost-effective installation on commercial and industrial job sites.
Navigating 1/0 conductors through high-voltage commercial raceways requires a cable that resists tangling and binding. The Priority-Plex® architecture maintains a stable, precision-twisted geometry that prevents conductors from overlapping or "bird-caging" inside the conduit. This significantly reduces pulling tension, protecting the insulation from sidewall pressure and ensuring a balanced load distribution across the entire pull.
High-Voltage Phase Management: Features industry-standard Brown, Orange, and Yellow conductors for immediate identification in 480/277V systems, streamlining termination in high-voltage switchgear.
Logistical Footprint Reduction: Consolidating three heavy-gauge leads onto a single reel drastically reduces the equipment overhead and setup time required for primary feeder pulls.
Rugged XHHW-2 Shielding: The cross-linked polyethylene (XLP) insulation is optimized for maximum heat dissipation, chemical resistance, and long-term moisture protection in underground ducts.
AA-8000 Series Performance: Provides the necessary 135-Amp capacity while remaining significantly lighter than copper, reducing the risk of equipment failure or rope snaps during difficult pulls.
Conductor Size: 1/0 AWG
Number of Conductors: 3 (Twisted)
Color Code: Brown, Orange, Yellow
Ampacity: 120 Amps at 75°C / 135 Amps at 90°C (NEC Table 310.16)

Industrial 480V Branch Circuits: The primary choice for supplying power to manufacturing machinery, compressors, and motor control centers.
Commercial Distribution: Ideal for routing power from the main service entrance to large distribution panels in shopping centers and office towers.
Institutional Infrastructure: A reliable choice for university campuses, hospital wings, and government complexes where high-load stability is critical.
Aggressive Raceway Pulls: The twisted geometry reduces surface-to-conduit friction, making it the superior option for long pulls through 2.5-inch or 3-inch rigid conduit.

This 1/0 AWG (pronounced "one-aught"), 3-conductor cable is specifically color-coded for 480V 3-phase industrial power systems. The Brown, Orange, and Yellow phase identification is the industry standard for 277/480V commercial and industrial distribution. It is most frequently used to feed mid-sized industrial motors, commercial HVAC equipment, and secondary distribution panels where high-voltage power is required without an integrated neutral.
Managing three separate 1/0 conductors through industrial conduit can be labor-intensive and prone to "jamming" in 90-degree elbows. Priority-Plex® factory-twists the Brown, Orange, and Yellow conductors into a single, synchronized helical bundle. This structural arrangement ensures that the conductors move as a single unit, preventing the wires from spreading out and wedging against the conduit walls. By reducing surface area contact with the pipe, the twist significantly lowers pulling friction, allowing for a faster installation with less risk of insulation damage.
In high-voltage systems, thermal stability and chemical resistance are critical for safety. XHHW-2 insulation is composed of Cross-Linked Polyethylene (XLPE), a "thermoset" material that offers superior performance over standard PVC. It will not melt or deform under emergency overload conditions or if exposed to high ambient heat in mechanical rooms. Furthermore, XLPE provides excellent resistance to industrial oils, chemicals, and moisture, making it the ideal choice for the harsh conditions found in manufacturing facilities and refineries.
The allowable ampacity for 1/0 Aluminum is determined by the temperature rating of your equipment terminations per NEC Table 310.16. For 75°C Terminations, it is rated for 120 Amps. For 90°C Terminations, it is rated for 135 Amps. Because all three conductors in this Priority-Plex® bundle are current-carrying phases, standard NEC adjustment factors must be applied if the circuit is installed in a raceway with multiple other conductors to prevent excessive heat buildup.
Proper infrastructure planning is necessary to accommodate the diameter and stiffness of 1/0 AWG wire. To satisfy the NEC 40% fill requirement, a 1.25-inch or 1.5-inch conduit is generally required. Professional installers typically recommend a 1.5-inch pipe for long runs to ensure the twisted bundle passes through bends without binding. Always use UL-listed AL9CU lugs and ensure that you wire-brush the 8000-series aluminum alloy and apply an antioxidant joint compound before torquing the connection to the manufacturer’s specified tension.
