While often used interchangeably, "URD" stands for Underground Residential Distribution (typically owned by utilities), and "USE-2" is the UL designation for Underground Service Entrance cable. Our cable is dual-rated, meaning it meets the stringent UL 854 standards required for utility-grade reliability and residential service entrance applications.
Yes. This cable is specifically engineered for direct burial. It is built to withstand soil moisture, mechanical pressure, and chemical exposure without the need for additional conduit, provided the trench is prepared in accordance with local electrical codes.
While this cable is optimized for underground utility distribution (URD), it is not a "Service Drop" (triplex for overhead) cable. Service Drop cable requires a specific ACSR messenger for structural support. You should use approved Service Drop cable for overhead spans to comply with safety standards.
For 3/0-3/0-3/0 URD, the ampacity depends on the installation method:
Direct Burial:Â 280 Amps
In Duct/Conduit:Â 205 Amps
Note: Always refer to NEC 310.15 or consult a licensed electrician to verify derating requirements based on your local environment.
Yes. Per NEC Table 300.5, direct-buried cable typically requires a minimum cover of 24 inches (or 18 inches if protected by a specific RCD/GFCI system). However, always verify your local municipal codes, as some jurisdictions have stricter requirements for service-entrance conductors.
We stock a full range of single conductor, duplex, triplex & quadruplex URD cables including 2 AWG URD, 1/0 URD, 2/0 URD, 4/0 URD & 750 MCM URD You can browse our complete inventory and view detailed specifications for each size in our Full Aluminum URD Collection here.
