Genesis Cable 47040907 Thermostat Solid Wire 20AWG 5C 250ft

Product Description

The GENESIS CABLE 47040907 is a 20 AWG 5-conductor solid thermostat wire rated for Class 2 (CL2) low-voltage applications. Sold in a 250-foot spool with a brown jacket, it is designed for reliable signal transmission between thermostats, control boards, and HVAC equipment. The solid copper conductors maintain consistent resistance over the run length, making this wire a dependable choice for residential and light commercial thermostat wiring jobs. HVAC technicians and electricians install this cable during new construction, system replacements, and control wiring upgrades.

This wire is used in low-voltage thermostat circuits connecting heating and cooling equipment to a wall thermostat or zone controller. It is suited for residential furnaces, air conditioners, heat pumps, and zone control systems that require a 5-conductor hookup — covering common, heat, cool, fan, and auxiliary or reversing valve terminals. The brown jacket color aids in cable identification in multi-wire installations and mechanical rooms.

Key Features

• 20 AWG solid copper conductors for stable, low-resistance signal runs
• 5-conductor configuration supports multi-stage and heat pump thermostat wiring
• CL2 rating meets NEC Class 2 requirements for low-voltage control wiring
• 250-foot spool reduces splicing on longer residential and light commercial runs
• Brown PVC jacket provides UV and abrasion resistance during installation

Compatibility

Designed as an OEM-style replacement and new-install solution for residential and light commercial low-voltage thermostat wiring applications requiring 20 AWG 5-conductor CL2-rated cable.

Installation Notes

Installation should be performed by a licensed HVAC technician or electrician in accordance with NEC Class 2 low-voltage wiring requirements. De-energize the thermostat circuit and disconnect power to the air handler or furnace control board before pulling or terminating wire. Avoid running low-voltage thermostat wire in the same conduit as line-voltage conductors. Secure the cable at regular intervals per local code requirements and protect it from sharp edges or pinch points during rough-in.
