About Wire and Cable

About Conduit

Use For: Buildings
Flexible
Temperature Range: 15° to 190° F
Insulation:
Outer: Aluminum Armor
Inner: PVC Plastic

Also known as AC and BX cable, this cable has an uninsulated aluminum ground wire that's in constant contact with the aluminum armor, so it can be used for bonding and grounding. The uninsulated ground wire is not counted in the number of wires. The armor acts as conduit to protect the THHN building wires. It's often used along the exterior of walls to carry power to outlet boxes. All are flame rated VW-1 to meet requirements for preventing the spread of flames based on a timed test with vertically suspended material.
