More About This Collection THW & THWN & THHN Solid Wire
Solid building wire from Southwire, including 10/1, 12/1 and 14/1 THHN and an 18 gauge TFN wire, each in a 500 ft. length.
Solid wire keeps its shape when bent. A lower gauge number means thicker wire, so confirm the gauge and insulation type in each product name.
