Honeywell 14/4msr50-600v Thhn Tray Cable Mini-split 50 Ft

Product Description

The HONEYWELL 14/4msr50-600v is a 14 AWG, 4-conductor stranded THHN tray cable rated at 600 volts, supplied in a 50-foot roll. It is designed for use as low-voltage power and control wiring in mini-split systems and other HVAC applications that require a flexible, multi-conductor run between indoor and outdoor units. The stranded construction improves flexibility during routing through conduit, wire trays, or open-air cable paths. The 600-volt rating provides a safe margin well above typical mini-split operating voltages. HVAC technicians and electrical contractors handle installation of this cable type.

This cable is suited for residential and light commercial mini-split installations where a single multi-conductor run must carry both power and control signals between the air handler and the condensing unit. It is also applicable in other HVAC control wiring scenarios that require a rated tray cable. The 50-foot roll length accommodates most standard residential line-set runs without splicing.

Key Features

• 14 AWG stranded conductors for flexibility during installation
• 4-conductor configuration carries power and control signals in a single cable run
• 600-volt rating meets requirements for mini-split and general HVAC control wiring
• THHN-rated insulation for heat and moisture resistance
• Tray cable (TC) designation allows use in cable trays and conduit
• 50-foot roll length suits most residential mini-split line-set distances

Compatibility

Designed as an OEM-style replacement and new-installation wiring solution for mini-split systems and HVAC applications requiring 14 AWG 4-conductor 600-volt tray cable.

Installation Notes

Installation should be performed by a licensed HVAC technician or electrician in accordance with NEC Article 336 governing tray cable wiring methods. Disconnect and lock out all power to the system before making any wiring connections. Route the cable to avoid sharp bends, pinch points, and direct contact with refrigerant lines that may cause abrasion over time. Verify conductor terminations match the equipment manufacturer wiring diagram before restoring power.
