"The industry-standard for high-amperage residential, farm, and commercial 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 Fairfield 750-750-500 URD cable is the definitive high-capacity solution for major secondary underground power distribution. Engineered for the most demanding large-scale commercial developments and industrial service entrances, it provides a stable, high-performance solution for moving massive power loads. By utilizing high-conductivity 1350-H19 aluminum and a heavy-duty, sunlight-resistant XLP insulation, it offers the highest level of resistance to environmental degradation, moisture ingress, and thermal stress in its class.
600V Reliability: Rated for continuous operation in wet or dry locations at temperatures up to 90°C, ensuring stability under peak load conditions for industrial machinery and large complexes.
Sunlight-Resistant XLP: Advanced cross-linked polyethylene insulation prevents premature aging caused by UV exposure, maintaining structural integrity at the service entrance.
Easy-Identify Neutral: For faster installation and safer maintenance, the neutral conductor features three extruded yellow stripes and clear sequential footage markings.
Direct Burial Ready: Specifically built for the harsh conditions of underground utility distribution; can be installed directly in the earth or within large-diameter conduit/duct systems.

The ampacity depends on your installation method:
Note: Always consult your local electrical inspector and NEC Table 310.15 to ensure the ampacity meets your specific service calculation.
Yes. Fairfield 750 MCM URD is designed for direct burial. Its XLP insulation is specifically formulated to resist moisture and soil-based stressors, though at this size, many installers prefer conduit for added physical protection and ease of future replacement
Our 750 MCM Fairfield URD has a nominal OD of 2.40 in. / 60.96 mm. This cable is extremely heavy and has a significant bending radius; please plan your trenching or conduit pulls accordingly.
Technical Note: All values are nominal and subject to industry tolerances. It is the buyer’s responsibility to verify that all materials meet the specific requirements of the project and comply with local electrical codes. Neutral wire carries unbalanced load only.
Absolutely. Its high ampacity and 600V rating make it the industry standard for secondary feeders in large-scale industrial complexes, data centers, and manufacturing facilities. It is specifically engineered to handle the continuous high-load demands of heavy machinery and large distribution switchgear where smaller gauges would suffer from excessive heat or power loss.
