Sersuamr triug250-250-3/0prattmr 250 Kcmil Triplex Urd Wire

Product Description

The SERSUAMR triug250-250-3/0prattmr is a triplex aluminum 600-volt URD (Underground Residential Distribution) wire rated for direct burial and conduit/duct installations. Built with 250 kcmil aluminum phase conductors and an XLPE (cross-linked polyethylene) insulation system, this cable is engineered for underground power distribution runs in residential and light commercial settings. The 90-degree C temperature rating supports sustained load capacity, with a current rating of 345 amps in direct burial and 265 amps in conduit. Electricians and utility contractors rely on this cable type for service lateral and feeder applications where a durable, moisture-resistant underground solution is required.

This triplex URD cable is suited for underground service entrance and distribution feeder work in residential subdivisions, multi-family properties, and light commercial sites. The three-conductor configuration — two insulated phase conductors and one neutral — is a standard arrangement for single-phase 240/120-volt service laterals running from transformer to meter base. The 1000-foot reel length supports longer trench runs without mid-run splices. Installation is typically performed by licensed electricians working under NEC Article 310 and local utility specifications.

Key Features

• 250 kcmil aluminum conductors rated for 345 amps direct burial and 265 amps in conduit
• XLPE insulation provides resistance to moisture, heat, and abrasion in underground environments
• 600-volt rating covers standard residential and light commercial distribution voltages
• 90 degrees C temperature rating supports continuous high-load operation
• Three-conductor triplex design for single-phase service lateral and feeder runs
• 1000-foot reel length minimizes field splices on longer underground runs

Compatibility

Designed as a standard triplex aluminum 600-volt URD cable for direct burial and duct-bank installations in residential and light commercial underground electrical distribution systems.

Installation Notes

Installation must be performed by a licensed electrician in accordance with NEC Article 310 and applicable local utility requirements. De-energize and lock out all upstream overcurrent protective devices before making terminations. For direct burial, verify minimum burial depth per NEC Table 300.5 before backfilling. Avoid sharp bends during pulling to stay within the cable's minimum bend radius, and do not exceed the cable's rated pulling tension.
