18-12C Thermostat Wire is a low-voltage cable designed for power-limited circuits. It features 18 AWG solid copper conductors and 12 color-coded conductors, making it suitable for a variety of control applications in residential and commercial settings. This wire is commonly used to connect thermostats to HVAC systems, as well as for bell, alarm, and signal systems.
This 18-12C Thermostat Wire is primarily used for power-limited circuits in various systems. Its applications include connecting thermostats to air conditioning and heat pump units, as well as wiring for bell and alarm systems, signal systems, doorbells, and remote control units. It is ideal for situations where the voltage requirements do not exceed 300 volts.
The 18-12C Thermostat Wire contains 12 distinct conductor colors: White, Red, Green, Blue, Yellow, Brown, Orange, Black, Purple, Gray, Pink, and Tan. While specific functions can vary by HVAC system, common conventions include Red for power, White for heating, Yellow for cooling, Green for the fan, and Blue or Black often serving as a common (C) wire.
This thermostat wire is designed for power-limited circuits where the voltage does not exceed 300 volts. While typical HVAC control systems often operate at 24 volts, this wire is rated to safely handle up to 300 volts, providing a robust solution for various low-voltage applications.
