Mini-Split Wire

Wire for connecting mini-split indoor and outdoor units. The collection includes Southwire 14/4 stranded THHN 600V wire in black in 50 ft and 250 ft lengths, and a 14/4 x 50 ft stranded mini-split wire.

Most ductless systems use a 14/4 cable between the outdoor unit and each indoor head for power and communication, but check the installation manual for the gauge and conductor count. Measure the run length and add extra for routing. Confirm the wire type is suitable for outdoor or wet locations.
