Mini Split Ductless AC System 14 AWG 4 Conductor Black Stranded Communication Wire 14 Gauge 4 Conductor 600V Direct Burial Rated 500ft Wooden Spool (Black).
This is the appropriate size wire to install your mini split system. 14 gauge is thick enough to allow the power and communication lines to function properly for single & multi-zone applications. Common 18/8 thermostat wire will NOT work properly and may result in issues later. Stranded copper is also recommended for mini split installs versus solid. This is rated to 600V and is specifically designed for ductless mini split applications.
