The Genesis 14/4 THHN wire (10703908) 50-ft coil is purpose-built for mini-split and HVAC tray-cable run. Designed for ductless heat-pump and air-conditioning installs, this four-conductor cable handles both outdoor weather and direct burial without extra conduit. Flexible 14 AWG stranded copper slips easily through line-set covers, while the tough outer jacket keeps moisture and sunlight from harming the conductors.
Why Choose This Cable
Outdoor / direct-burial rated (Type TC-ER-JP)
Lay it in a trench or strap it along the wall—no separate conduit needed for most mini-split runs.
Sunlight- and water-resistant jacket
UV-stable PVC shrugs off rain, snow, and rooftop sun exposure with temperature range of –20 °C to +90 °C (jacket).
4 Stranded 14 AWG bare-copper conductors (19 strands each)
More flexible than solid wire, so it bends around corners and pulls through tight chases with less risk of kinking.
Color-coded THHN insulation
Black, white, red, and green make indoor and outdoor terminations straightforward.
600 V rating
Plenty of headroom for compressor and communication circuits on modern inverter mini-splits.
Typical Uses
- Interconnecting mini-split indoor heads to outdoor condensers
- Control wiring for small heat pumps or ductless VRF branches
- Low-voltage power/communication runs where a weather-tight, burial-ready cable is required
