Southwire 553025507 18 Awg 2-conductor Thermostat Wire

Product Description

The SOUTHWIRE 553025507 is an 18 AWG 2-conductor thermostat wire designed for low-voltage control wiring in residential and light commercial HVAC systems. This wire connects thermostats to heating and cooling equipment, carrying 24-volt control signals between the thermostat and the air handler, furnace, or condensing unit. Sold per foot, it allows contractors and technicians to purchase the exact length needed for each job. The 18 AWG gauge provides reliable signal transmission across typical residential thermostat wiring runs. HVAC technicians and electricians install this wire during new system installations, equipment replacements, and thermostat upgrades.

This thermostat wire is suited for residential and light commercial low-voltage control circuits, including connections between thermostats and furnaces, air handlers, heat pumps, and condensing units. The 2-conductor configuration covers basic heating-only or simple single-stage heating and cooling applications. Sold by the foot, it is a practical solution for service calls where only a short run is needed or when splicing into an existing wiring run is not appropriate.

Key Features

• 18 AWG 2-conductor construction for low-voltage thermostat control circuits
• Sold per foot for job-specific purchasing flexibility
• Suitable for 24-volt HVAC control wiring applications
• Designed for residential and light commercial system installations

Compatibility

Designed as a standard low-voltage thermostat wire replacement or extension for residential and light commercial HVAC control wiring applications requiring an 18 AWG 2-conductor wire.

Installation Notes

Installation is typically performed by a licensed HVAC technician or electrician. Always power down the HVAC system and set the thermostat to the off position before disconnecting or connecting thermostat wiring. Low-voltage thermostat wiring should be routed away from line-voltage conductors to prevent interference. Follow NEC requirements for low-voltage wiring and consult local codes before installation.
