18-2C Thermostat Wire is a type of electrical cable primarily designed for low-voltage power limited circuits. It connects devices like thermostats, air conditioning units, heat pumps, and various bell and alarm systems. This wire facilitates communication and power transmission between your control unit and the HVAC system or other low-voltage applications.

  • Conductor Gauge: 18 AWG
  • Number of Conductors: 2
  • Conductor Material: Solid soft drawn copper
  • Insulation Material: Heat and moisture resistant PVC
  • Jacket Material: Heat, moisture, and sunlight resistant PVC
  • Voltage Rating: Up to 300 volts (though commonly used in 24V systems)
  • Temperature Rating: -20°C to +60°C (-4°F to 140°F)
  • Jacket Colors: Brown or White
  • Conductor Colors: Red and White

In "18-2C Thermostat Wire," "18" refers to the wire's gauge, which is 18 AWG (American Wire Gauge). This indicates the thickness of each conductor. "2C" signifies that the cable contains two individual conductors within its outer jacket.

This wire is ideal for power limited circuits in various systems. Common applications include wiring for thermostats, air conditioning and heat pump controls, bell and alarm systems, signal systems, doorbells, and remote control units. It is designed for low-voltage needs where the voltage does not exceed 300 volts.

This 18-2C Thermostat Wire is rated for voltages that do not exceed 300 volts. While it can handle up to 300V, it is most commonly used in low-voltage applications, such as 24-volt HVAC systems.
