- What is 2-2-2-4 URD cable used for?
- It feeds a subpanel or service from a meter or transformer underground. The three size 2 conductors carry the two hots and neutral, and the size 4 conductor serves as ground.
- Can it go straight in the ground without conduit?
- Yes. It is rated for direct burial at 155 amps. In duct, the rating drops to 115 amps.
- What size breaker does it take?
- Direct burial, the cable is rated 155 amps, so a 150-amp feed is the usual match. In conduit or duct, size the breaker to the 115-amp rating.
- How do I connect aluminum conductors?
- Use lugs and connectors listed for aluminum, and apply antioxidant paste to the stripped strands. Retorque terminations to the lug manufacturer's spec.
- What is the outside diameter?
- About 0.97 in overall, with each single conductor around 0.40 in. Plan burial depth and any sleeve sizing around that.
