Coleman Cable 58340802 Mini-split Cable 14/4 Thhn 600V

Product Description

The COLEMAN CABLE 58340802 is a 250-foot spool of 14/4 THHN mini-split cable designed for the low-voltage wiring runs that connect indoor air handlers to outdoor condensing units in ductless mini-split systems. The cable features PVC insulation and a 600-volt rating, meeting the electrical demands of residential and light-commercial mini-split installations. Four 14-gauge THHN conductors are bundled in a single jacket, keeping the run clean and simplifying pull-through conduit or open-air routing. Licensed HVAC technicians and electricians install this cable during new mini-split installations or equipment replacements.

This cable is suited for ductless mini-split systems requiring a dedicated communication and power run between the indoor and outdoor units. The 250-foot spool accommodates longer line set runs typical in multi-zone residential installations or commercial applications where the air handler and condenser are separated by significant distance. The 14/4 THHN construction is a widely accepted configuration for mini-split wiring where the equipment manufacturer specifies a four-conductor, 14-gauge supply.

Key Features

• 250-foot spool provides enough length for longer or multi-unit mini-split runs
• 14/4 THHN conductors rated for 600 volts
• PVC insulation resists moisture and abrasion during conduit or exposed routing
• Four-conductor configuration supports standard mini-split communication and power wiring
• Single-jacket design simplifies routing alongside refrigerant line sets

Compatibility

Designed as an OEM-style wiring solution for ductless mini-split systems requiring 14/4 THHN, 600-volt-rated cable between indoor and outdoor units.

Installation Notes

Installation should be performed by a licensed electrician or HVAC technician in accordance with NEC Article 440 and the mini-split manufacturer's wiring diagram. Always disconnect and lock out power at the breaker before making any wiring connections at the indoor or outdoor unit. Route cable through conduit or secure it at appropriate intervals per local code requirements. Verify conductor count and gauge against the equipment nameplate before beginning the run.
