Our take on the 4/0-4/0-2/0 Sweetbriar Triplex Aluminum Conductor Underground Direct Burial 600V URD Cable

This is Sweetbriar triplex aluminum URD cable for single-phase underground secondary distribution: two 4/0 AWG phase conductors and a 2/0 AWG neutral, rated 600V. Aluminum conductors with XLPE insulation make it moisture- and heat-resistant to 90°C, for direct burial or duct runs. Ampacity is 315 A direct buried and 240 A in duct. It suits service drops from a transformer to a building, where copper URD of the same size would cost more and weigh more; aluminum needs antioxidant and proper terminations at connections. Buyers rate it highly, and the main trade-offs are the handling care aluminum demands and the limited use for three-phase work.

Pros
  • Two 4/0 phase conductors plus 2/0 neutral in one triplex assembly
  • 315 A allowable ampacity direct buried, 240 A in duct
  • XLPE insulation rated to 90°C and moisture-resistant
  • Rated 600V for underground secondary distribution
  • Aluminum is lighter and less costly than equivalent copper
Cons
  • Aluminum terminations need antioxidant and correct torque
  • Not for three-phase service; single-phase only
  • Neutral is smaller than the phases, so check load balance
  • Direct-burial ampacity depends on soil and burial depth

About the 4/0-4/0-2/0 Sweetbriar Triplex Aluminum Conductor Underground Direct Burial 600V URD Cable

This is a 600V triplex URD cable with aluminum conductors, made for underground single-phase secondary power distribution. It can be direct buried or installed in ducts. It has two 4/0 AWG phase conductors and one 2/0 AWG neutral.

The conductors are aluminum, in either concentric or compressed stranding. Compressed conductors are less bulky, stronger and tougher. Stranded conductors are flexible and have lower electrical resistance. The insulation is black cross-linked polyethylene (XLPE). It is water tight and resists corrosive substances, oil, heat and flame. The cable is rated for a maximum operating temperature of 90°C and works in wet and dry environments.

It is used for single-phase service drops from transformers to buildings and for supplying meters in residential and rural areas. It also serves small commercial buildings, municipal facilities, single-family homes and small multi-unit residences. Other uses include street lighting, residential solar and battery storage connections, and temporary power for construction, events and backups.

Questions and answers

What is this cable used for?
Single-phase underground secondary distribution, typically a service drop from a transformer to a building. It is rated 600V and can be direct buried or run in duct.
What are the conductor sizes?
Two 4/0 AWG aluminum phase conductors and one 2/0 AWG aluminum neutral, in triplex configuration.
How much current can it carry?
315 amps direct buried and 240 amps in duct, per the manufacturer's allowable ampacity. Actual capacity depends on soil, depth and installation conditions.
Can it be buried directly in the ground?
Yes. It is listed for direct burial and for duct installation, with XLPE insulation rated for wet and dry locations to 90°C.
Does it work for three-phase service?
No. The two phase conductors make it a single-phase cable. Three-phase work needs a different conductor arrangement.
What should I know about terminating aluminum?
Use connectors rated for aluminum, apply antioxidant compound and torque to the connector maker's spec. Aluminum connections loosen if not tightened properly.
