Our take on the 4/0,4/0 & 2/0 Sweetbriar Aluminum Triplex URD Direct Burial Cable

Sweetbriar's triplex URD cable is a direct-burial secondary distribution assembly: two 4/0 aluminum phase conductors and one 2/0 aluminum neutral, twisted together and insulated with black XLPE. It is built for 600 V underground service runs, such as feeding a detached building, a pedestal or a subpanel from a meter. The compressed Class B stranded 1350 aluminum keeps it lighter and easier to pull than equivalent copper, and the twisted assembly installs without conduit in direct-burial trenches. It meets UL 854 and ICEA S-105-692, the standards utilities and inspectors expect for this class of cable. Buyers comparing it with copper URD get a lower-cost conductor that needs aluminum-rated lugs and a bit more care at terminations.

Questions and answers

What is triplex URD cable used for?
It is used for underground secondary distribution: service drops to outbuildings, subpanels and pedestals at 600 V or less. The twisted assembly is designed to be buried directly.
Can it be buried without conduit?
Yes. URD cable is made for direct burial in a trench. Check local code for burial depth and any sand bedding or warning tape requirements.
What size breaker does 4/0 aluminum triplex support?
Ampacity depends on the installation method and the code edition your inspector uses. Have a licensed electrician size the overcurrent protection for your run; do not assume a single number.
Does it work with standard lugs and panels?
Only with connectors listed for aluminum conductors. Use antioxidant compound on the strands and torque terminations to the manufacturer's spec.
How does it compare with copper URD?
Aluminum costs less and weighs less, but it needs a larger size for the same current and more careful terminations. Copper is more compact and easier to terminate.
What is in the box?
One continuous length of twisted cable with two 4/0 phase conductors and one 2/0 neutral, all XLPE insulated. Terminations and connectors are not included.
Where is the 4/0,4/0 & 2/0 Sweetbriar Aluminum Triplex URD Direct Burial Cable cheapest?
At Global Cable and Wire, for $3.75, as of our latest check.
