Southwire 58225707 14/4 Mini Split Thhn Cable 1000 Ft

Product Description

The SOUTHWIRE 58225707 is a 14 AWG, 4-conductor stranded THHN cable rated at 600 volts, supplied on a 1000-foot reel. Each conductor uses a 7-strand configuration, which improves flexibility during pull-through compared to solid wire. The cable is designed specifically for mini split HVAC system wiring, where multiple conductors are needed to carry power and control signals between the indoor air handler and the outdoor condensing unit. Electricians and HVAC technicians install this cable in both residential and light commercial applications. The THHN insulation rating makes it suitable for use in conduit or as part of an approved wiring method per NEC requirements.

This cable is used to interconnect the indoor and outdoor units of ductless mini split systems. The four-conductor layout accommodates the typical wiring requirements of single-zone mini split systems, which commonly need separate runs for power, common, and communication conductors. The 1000-foot reel format is well suited for contractors running multiple jobs or larger commercial installations where bulk footage reduces material cost per run. Color-coded conductors — black, red, white, and green — support straightforward termination at both the air handler and the condenser.

Key Features

• 14 AWG, 7-strand conductors provide flexibility for routing through conduit
• 4-conductor layout supports typical mini split power and control wiring
• 600V THHN insulation rating for use in conduit per NEC-compliant installations
• 1000-foot reel format reduces per-foot cost on multi-unit or commercial jobs
• Color-coded conductors (black, red, white, green) simplify field termination

Compatibility

Designed for use with ductless mini split HVAC systems requiring 14 AWG 4-conductor interconnect wiring in residential or commercial installations.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize the circuit and lock out the disconnect before making any terminations at the air handler or condensing unit. Route the cable through approved conduit or raceways as required by the installation environment and local jurisdiction. Verify that the wire gauge and circuit protection are sized correctly per the mini split manufacturer's specifications before energizing.
