- Can this cable be buried without conduit?
- Yes. It is rated for direct burial, so it can go straight into a trench. Local code may still require conduit where it rises out of the ground or crosses under a driveway.
- What size breaker does 2-2-2-4 aluminum support?
- The cable is rated 155 A in direct burial and 115 A in duct. Most installs protect it at 100 A or 125 A depending on the run and code, so confirm with your inspector before sizing the breaker.
- Do I need special lugs for aluminum conductors?
- Yes. Use lugs and connectors listed for aluminum, apply antioxidant paste and torque to the manufacturer's spec. Recheck the torque after the first heating cycle.
- Is this the same as 2-2-2-4 copper?
- No. Aluminum carries less current for the same gauge, so 2 AWG aluminum is not a drop-in swap for 2 AWG copper. Size the conductors to the load and the code table.
- What is included in the box?
- One continuous 150 ft length of quadruplex URD cable. Lugs, paste and conduit are not included.
