The 4/0-4/0-4/0-2/0 Direct Burial Cable, also known as 4/0 Quadruplex URD Cable, is a type of underground aluminum distribution cable designed for secondary power distribution systems. It’s commonly used to deliver power from a pad-mounted transformer to a residential or light commercial building, especially in underground utility systems.

Cable Configuration
Cable ConfigurationThe cable is called 4/0-4/0-4/0-2/0 because it has three 4/0 AWG phase conductors and one 2/0 AWG neutral conductor. The larger gauge (4/0) wires are used to carry the phase power, while the smaller 2/0 gauge wire serves as the neutral. The conductors are twisted together in a quadruplex configuration to form a single cable assembly.
Breakdown:
Phase A Conductor: 4/0 AWG Aluminum
Phase B Conductor: 4/0 AWG Aluminum
Phase C Conductor: 4/0 AWG Aluminum
Neutral Conductor: 2/0 AWG Aluminum (usually with yellow stripe or jacket)
This specific arrangement helps balance the electrical load and ensures reliable power transmission over medium distances.

How is it Different from Standard URD Cable?
How is it Different from Standard URD Cable?While URD cable comes in various configurations (duplex, triplex, quadruplex), the 4/0-4/0-4/0-2/0 cable specifically refers to a quadruplex layout with heavier phase conductors, making it suitable for higher load requirements. It's commonly used when larger homes or small businesses need more electrical power than what smaller URD cables can handle.
