    About Wire and Cable
    industrial info icon

    Compare wire vs. cable and choose the right option based on gauge, number of conductors, insulation, and current rating.

    Building Wire

    Install this copper wire in conduit and cable trays in commercial and industrial buildings. It's also known as branch circuit wire. The outer jacket is designed to be installed without applying pulling lubricant.

    TFFN, THHN/THWN, and THHN/THWN-2

    Stranded

    Stranded wire is flexible, so it’s pliable enough to be pulled around corners.
    Wire with a nylon outer jacket resists oil and water.
    TFFN Cable—TFFN wire is also known as fixture wire. It’s for use in dry locations.
    THHN Cable—THHN wire can be used in dry or damp locations where wire is exposed to condensation or moisture, such as a basement.
    THWN Cable and THWN-2 Cable—THWN and THWN-2 wire can be used in both wet and dry environments.
    UL 2556 VW-1—Flame rated VW-1 wire meets requirements for preventing the spread of flames based on a timed test with vertically suspended material.

    Aluminum Building Wire

    Image of Product. Side1 orientation. Building Wire. Aluminum Building Wire.
    Mend or extend aluminum wire often found in older buildings. This wire isn’t recommended for new wiring, since it’s more likely to overheat than copper when conducting electricity. However, it’s safer to maintain existing aluminum wire with aluminum rather than mixing materials. Building wire is also known as branch circuit wire.
    This wire has an outer layer of nylon insulation that won't degrade from oil and water. It’s designed to be pulled through conduit without pulling lubricants. THHN and THWN-2 designated, this wire can be used in damp places.
