- What is quadruplex URD cable used for?
- It feeds secondary distribution circuits, typically the underground service run from a transformer or meter to a panel. It works in duct or buried directly in the ground.
- Why is the neutral smaller than the phase conductors?
- The #1 AWG neutral is a reduced-size conductor. That suits single-phase 120/240V service where the neutral carries only the imbalance between the two hot legs, not full phase current.
- Can it be buried without conduit?
- Yes. It is listed for direct burial as well as duct installation. Check local code for required burial depth and any protection where it rises out of the ground.
- How does it compare with copper URD?
- Copper carries more current per gauge and is less fussy at terminations. Aluminum is lighter, easier to pull and the usual pick for long underground runs when sized correctly.
- What temperature and voltage is it rated for?
- 600 volts, with a maximum conductor operating temperature of 90°C in both wet and dry locations.
- What do I need at the terminations?
- Use lugs and connectors listed for aluminum, and an antioxidant compound on the strands. Retorque per the connector maker's spec, since aluminum can loosen over time.
