Southwire/coleman Cable 55302-05-07 18/2 Thermostat Wire 500 Ft

Product Description

The SOUTHWIRE/COLEMAN CABLE 55302-05-07 is an 18 AWG, 2-conductor jacketed thermostat wire supplied on a 500-foot spool. The solid copper conductors are wrapped in a brown vinyl jacket rated for a maximum of 30 volts, making it well suited for low-voltage control wiring in residential and light commercial applications. The spooled format reduces kinking during pulls and supports clean, organized job-site handling. HVAC technicians, alarm installers, and electricians reach for this wire when running control circuits between thermostats and heating or cooling equipment.

This wire is commonly installed in residential HVAC systems to connect thermostats to furnaces, air handlers, and heat pumps. It also serves bell and intercom wiring circuits that operate within the 30-volt maximum rating. The 2-conductor configuration covers standard single-stage heating or cooling control runs. The solid conductor construction is appropriate for terminal-block and screw-type connections found on most residential control boards and thermostat sub-bases.

Key Features

• 18 AWG solid conductor construction for reliable low-voltage signal transfer
• 2-conductor configuration for standard single-stage thermostat or bell/intercom circuits
• 30-volt maximum rating suitable for Class 2 low-voltage control wiring
• Brown vinyl jacketing for identification and mechanical protection
• 500-foot spool format minimizes tangling and speeds installation pulls

Compatibility

Designed for use in low-voltage thermostat, bell, and intercom wiring applications rated at 30 volts maximum in residential and light commercial systems.

Installation Notes

Installation should be performed by a licensed HVAC technician or electrician in accordance with NEC Article 725 Class 2 low-voltage wiring requirements. Power down the thermostat and control system at the breaker before making any wire terminations. Avoid routing this wire in the same conduit or raceway as line-voltage conductors. Secure the spool on a reel stand during pulls to prevent conductor kinking or jacket damage.
