Honeywell 14/4msr250-600v Mini Split Wire 14/4 Awg 600V

Product Description

The HONEYWELL 14/4msr250-600v is a 250-foot, 4-conductor mini split wire designed to connect the indoor air handler to the outdoor unit in mini split heat pump and air conditioning systems. Rated at 600 volts and built to the UL 1277 Tray Cable standard, this cable carries both electrical power and communication signals between the two units. The wire uses 14 AWG stranded bare copper conductors with PVC and nylon insulation, making it suitable for the demanding requirements of mini split installations. Licensed HVAC technicians and skilled installers rely on correctly rated wire like this to ensure safe, code-compliant system operation.

This cable is intended for mini split heat pump and mini split air conditioning installations where the indoor air handler must receive power from the outdoor unit and maintain a communication link over the same cable run. It is appropriate for residential and light commercial applications. The 250-foot spool length accommodates longer line set runs and installations where the indoor and outdoor units are separated by significant distance. The UV-resistant jacket and direct burial rating expand its usefulness in exposed or underground routing scenarios typical in many installations.

Key Features

• 14 AWG stranded bare copper conductors, 4-conductor configuration for combined power and communications
• 600V rating meets the electrical requirements of standard mini split systems
• UL Listed and rated to UL 1277 Tray Cable standard
• PVC jacket with UV resistance for outdoor and exposed routing
• Direct burial rated for underground conduit or direct-earth installation
• Temperature range of -4 degrees F to 194 degrees F (-20 degrees C to 90 degrees C)

Compatibility

Designed as a replacement or new-installation wire for mini split heat pump and mini split air conditioning systems requiring 14/4 AWG, 600V-rated cable between the indoor air handler and outdoor unit. Suitable for industrial power or control circuit applications per UL 1277.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified electrician in accordance with the National Electrical Code (NEC) and any applicable local codes. Disconnect and lock out power at the breaker before making any wire connections at either the indoor or outdoor unit. Route the cable to avoid sharp edges or pinch points, and use approved conduit or fittings where required by code. Do not exceed the cable's rated voltage or temperature limits.
