"The industry-standard for heavy-duty secondary three-phase power distribution. Engineered for reliable 600V delivery, this cable is rated for both direct burial and duct installations, featuring sunlight-resistant XLP insulation for robust, long-term underground performance."
The Wake Forest configuration is engineered to maximize cost-efficiency without sacrificing performance. By utilizing a reduced neutral, this cable reduces overall weight and material costs while providing the heavy-duty 4/0 ampacity needed for large residential services, commercial buildings, and farm infrastructure.
High-Capacity Delivery: Three 4/0 AWG phase conductors provide robust power handling for secondary utility feeds.
Reduced Neutral Efficiency: The 2/0 AWG neutral is factory-sized to meet standard electrical requirements for balanced loads, reducing cable diameter and cost.
Rugged XLPE Insulation: The cross-linked polyethylene jacket is moisture, heat, and sunlight resistant, ensuring long-term reliability in direct-burial environments.
Labor-Saving Design: The quadruplexed (twisted) construction allows all four conductors to be pulled from a single reel, drastically reducing setup time and labor.

Note: These ratings are based on a 90°C conductor temperature. Most residential 200A services use 4/0 Aluminum to satisfy the 75°C terminal requirements of the breaker. Always consult with your local electrical inspector to ensure the cable meets your specific load and environmental requirements.
URD stands for Underground Residential Distribution. It is a category of electrical cable specifically engineered for direct burial in the earth. Unlike standard indoor wire, URD is built with rugged XLPE (Cross-Linked Polyethylene) insulation that is chemically designed to resist moisture, soil acids, and mechanical pressure without needing a protective outer jacket or conduit.
Yes, it is specifically designed for Direct Burial. Its XLPE insulation is rated for long-term exposure to soil moisture and chemicals. For safety, ensure it is buried at the depth required by your local code (usually 24 inches) and use a layer of sand or stone-free fill to protect the insulation from sharp debris.
Pro Tip: Even though it's direct burial, running it through a PVC sleeve where it leaves the ground protects it from weed-whackers and lawnmowers."
Typically, yes. With an ampacity rating that covers the 200A threshold, Wake Forest is the standard cable for a 200A 3-phase service entrance. It provides the necessary capacity while remaining much more cost-effective than copper alternatives.
You can use standard large-gauge wire strippers and cutters. However, you must use AL9CU rated lugs and apply an antioxidant joint compound to the stripped ends. This prevents the aluminum from oxidizing, which is vital for maintaining a cool, safe connection over time.
This is a "Reduced Neutral." In many 3-phase systems, the neutral only carries the "unbalanced" portion of the load. A 2/0 AWG neutral in this Wake Forest assembly saves money and reduces the total cable diameter, making it easier to pull through conduit while still complying with NEC standards for most secondary feeds.
Aluminum URD is the industry standard for underground utility feeds because it is significantly more cost-effective and lighter than copper. At the 4/0 size, aluminum provides the necessary ampacity for large residential and commercial feeds at a fraction of the cost of copper.
