Southwire 552060407 Thermostat Cable 20 Awg 6 Conductor

Product Description

The SOUTHWIRE 552060407 is a 20 AWG, 6-conductor thermostat cable designed for low-voltage HVAC control wiring applications. The cable features a brown PVC jacket rated for sunlight resistance, making it suitable for both indoor and exposed outdoor routing runs. At 0.16 inches in diameter, it routes cleanly through conduit, wall cavities, and cable management systems. This cable is sold in 1-foot cut increments with a 250-foot minimum cut length and is available on a 1,000-foot coil. HVAC technicians and installers use this cable to wire thermostats, zone controllers, and other low-voltage control components in residential and light commercial systems.

This thermostat cable is well suited for residential forced-air heating and cooling systems, heat pump installations, zone control panels, and similar low-voltage HVAC control circuits. The 6-conductor configuration accommodates multi-stage equipment wiring, including systems with separate heating, cooling, fan, and auxiliary heat terminals. The sunlight-resistant jacket allows routing along exterior walls or in attic spaces where UV exposure is a concern. It is commonly installed by licensed HVAC technicians during new construction and retrofit projects.

Compatibility

Designed as a standard low-voltage thermostat cable for use with residential and light commercial HVAC control systems requiring a 20 AWG, 6-conductor wire configuration.

Installation Notes

This cable is installed by licensed HVAC technicians working with low-voltage control circuits, typically 24-volt systems. De-energize all low-voltage control circuits and disconnect power at the air handler or furnace before making any wiring connections. Route cable away from high-voltage wiring to avoid interference, and follow all applicable NEC low-voltage wiring guidelines for separation and protection. Do not exceed the rated voltage and amperage limits for low-voltage thermostat wiring.
