The 1 AWG URD is a robust choice for secondary underground distribution, high-capacity residential and farm sub-panel feeds, and custom underground routing where a larger gauge is required to minimize voltage drop over distance.
Single conductor URD is the best choice when your project requires independent conductor management, such as custom underground routing, specific phase-pulling in tight conduits, or replacing a single damaged lead in an existing distribution run.
Yes. The Kenyon 1 AWG URD is designed for direct burial. The XLP insulation is specifically formulated to resist moisture and soil-based stressors without the need for additional protective conduit.
The ampacity for 1 AWG Aluminum URD is 175 Amps for direct burial and 130 Amps when installed in a duct or conduit. Always refer to NEC 310.15 or consult a licensed electrician to verify derating requirements for your specific installation environment.
No. This cable is strictly designed for underground utility distribution (direct burial or conduit). It does not meet the flame-retardant standards needed for residential branch circuits or interior wiring. Always use NEC-compliant interior wiring (like NM-B or MC cable) for interior runs.
We stock a full range of single conductor, duplex, triplex & quadruplex URD cables including 2 AWG URD, 1/0 URD, 2/0 URD, & 3/0 URD. You can browse our complete inventory and view detailed specifications for each size in our Full Aluminum URD Collection here.
URD wire stands for Underground Residential Distribution. This cable is specifically engineered for direct burial, meaning you can place it in a trench without conduit (provided you follow local burial depth codes). It is rated for 600 Volts and is rugged enough to withstand the chemical and physical stresses of being surrounded by soil and moisture.
