4 AWG Single Conductor Aluminum URD Direct Burial Cable (Mercer)

"Designed for 600V secondary power distribution, this single-conductor URD cable is built for performance. Featuring sunlight-resistant XLP insulation, it is rated for both direct burial and duct installations, providing a reliable, long-term solution for underground utility and sub-panel feeds."

Why Choose 2 AWG Aluminum URD?

This cable is the industry standard for secondary underground power feeds where independent phase management is required. Its 1350-H19 aluminum construction and XLP insulation ensure maximum durability against moisture and environmental stress.

600V Power Rating: Consistent performance in wet or dry locations up to 90°C.

Direct Burial Rated: Specifically designed to be buried directly in the earth without protective conduit.

Sunlight Resistant: XLP insulation prevents UV-driven degradation.

Versatile Installation: Optimized for direct-trench or conduit/duct applications.

Common Applications

Secondary Underground Distribution: Power feed from transformer to service entrance.

Residential & Farm Power: Reliable sub-panel feeds and outbuilding power.

Underground Routing: Ideal for direct-burial trenching or pull-through conduit.

Custom Phase Management: Because this is a single conductor, it is frequently used in custom underground layouts where the electrician needs to manage individual phases (for example, in complex commercial underground runs or when replacing a single damaged lead in an existing circuit).

Technical Note: All values are nominal and subject to industry tolerances and manufacturer corrections. Specifications are subject to change without notice. It is the buyer’s responsibility to verify that all materials meet the specific requirements of the project and comply with local electrical codes.
