For high-voltage industrial applications where physical space and labor efficiency are critical, this 250 MCM Priority-Plex® twisted assembly offers a streamlined solution for 480V power distribution. By factory-twisting three high-capacity conductors into a single, cohesive unit, it removes the logistical complexity of managing three separate heavy reels, ensuring a more synchronized and predictable pull through demanding commercial raceways.
Managing 250 MCM conductors in a traditional parallel pull can lead to uneven tension and "bird-caging" within the conduit. The Priority-Plex® design utilizes a precision-twisted architecture to ensure pulling forces are distributed equally across the bundle. This configuration also reduces the "sweep" area in bends, protecting the insulation from excessive sidewall pressure and abrasion.
480V System Optimized: Features industry-standard Brown, Orange, and Yellow color-coding for rapid phase identification and error-free termination in high-voltage panels.
Single-Source Payout: Consolidation onto one reel significantly reduces setup time and the equipment footprint, making it ideal for crowded industrial job sites.
Superior Thermal Performance: XHHW-2 cross-linked polyethylene (XLP) insulation is engineered for 90°C wet/dry performance, providing long-term reliability under continuous heavy loads.
AA-8000 Series Aluminum: Provides the necessary ampacity for industrial feeders while offering a massive weight reduction over copper, easing the physical demand on the installation crew.
Conductor Size: 250 MCM (kcmil)
Number of Conductors: 3 (Twisted)
Color Code: Brown, Orange, Yellow
Ampacity: 205 Amps at 75°C / 230 Amps at 90°C (NEC Table 310.16)

Industrial 480V Feeders: The primary solution for supplying power to heavy machinery, motor control centers, and processing equipment.
Commercial Main Distribution: Ideal for routing power from utility transformers to main distribution boards in large-scale retail and office developments.
High-Voltage Sub-Panels: Frequently used for feeding 200-Amp or 225-Amp sub-panels in manufacturing and institutional facilities.
Efficient Raceway Routing: The twisted geometry reduces surface friction, making it the preferred choice for long pulls through PVC, EMT, or rigid metal conduit.

This 250 MCM, 3-conductor cable is specifically color-coded for 480V 3-phase industrial power distribution. The Brown, Orange, and Yellow phase identification is the industry standard for high-voltage commercial and industrial systems (typically 277/480V). This cable is most frequently used as a feeder for commercial HVAC chillers, industrial pumps, and mid-sized motor control centers where a neutral is not required in the conduit run.
At the 250 MCM gauge, aluminum conductors become significantly stiffer and harder to manage than standard building wire. Priority-Plex® factory-twists the three phases into a single, synchronized bundle. This helical arrangement allows the conductors to flex as a single unit, which prevents the wires from "wedging" or crossing over each other in conduit bends. This synchronized movement drastically reduces the pulling tension required and eliminates the mechanical "memory" that causes individual heavy wires to fight the installer during training into switchgear.
In high-voltage industrial applications, thermal stability is critical to system longevity. XHHW-2 insulation is made of Cross-Linked Polyethylene (XLPE), a "thermoset" material. Unlike standard PVC (THHN), XLPE will not soften or flow if the conductors reach high temperatures during a peak load. Furthermore, XLPE provides superior resistance to industrial oils, chemicals, and moisture, ensuring that the 480V power backbone remains secure even in harsh processing plants or damp underground conduits.
The allowable ampacity for 250 MCM Aluminum is dictated by the temperature rating of the equipment terminations according to NEC Table 310.16. For 75°C Terminations, it is rated for 205 Amps. For 90°C Terminations, it is rated for 230 Amps. Because all three conductors in this Priority-Plex® bundle are current-carrying phases, standard NEC adjustment factors must be applied if the cable is installed in an environment with high ambient temperatures or if multiple circuits share the same raceway.
Proper infrastructure planning is essential for a successful 250 MCM installation. To comply with the NEC 40% fill requirement, a 2.5-inch or 3-inch conduit is generally required. Most professional installers prefer a 3-inch pipe to allow for easier movement of the twisted bundle through long-sweep elbows. Always use UL-listed AL9CU mechanical or compression lugs. It is a best practice to wire-brush the stripped 8000-series aluminum alloy and apply an antioxidant joint compound to ensure a low-resistance, corrosion-free connection at the terminal.
