What gauge wire is used for thermostats?
18 gauge
The most common thermostat cabling is 18/5 (18 gauge, 5 conductor), because 5 conductors typically offer enough functions for a modern thermostat/low voltage device.
How do you wire a 8 wire thermostat?
A typical eight-wire thermostat will have the following wire configuration: red wire to “R” terminal, white wire to “W” terminal, green wire to “G” terminal, yellow wire to “Y” terminal, black wire to “C” terminal, blue wire to “Y2” terminal, brown wire to “W2” terminal, and orange wire to “Aux” terminal.
What voltage is 18 2 thermostat wire rated for?

What is an 18 2 wire?
18-gauge, 2-conductor wire is some of the most common cabling used with alarm systems. When a wire is labeled as 18-2, it means that it is 18-gauge thickness (AWG) with 2-conductors (inner wires). You can generally swap out 18-gauge wire with slightly thicker or thinner wire.
What is a 18 gauge wire?
AWG stands for American wire gauge. It relates to the diameter of the wire. The more current capacity it can carry, the lower the AWG. A thicker 16AWG can carry 13 Amps, but a thinner 18AWG can only carry 10 Amps.
How many amps can 18 gauge wire take?
16 Amps
A conservative estimate for several feet of 18 gauge wire is 16 Amps. If you have only 12 gauge wire, the 18 gauge wire can handle more than 16 Amps.
What if there is no C wire for thermostat?
If you don’t see a wire you can identify as the C-wire, though, don’t despair yet – you may need to look behind your existing thermostat. If your current thermostat didn’t need a C-wire, it (or a wire that can be used as a C-wire) might be rolled up inside the wall.
How many amps can thermostat wire handle?
4 Amps
The thermostat wire isn’t sized for carrying capacity. The code requires the circuit to be Class 2, 30 volts and 100 VA maximum, with no more than 4 Amps. Most of the capacity may be required for the relays in the heating, ventilating, and air conditioning unit.
What voltage is thermostat wire rated for?
A Class 2 power-limited cable for use in thermostat controls applications, bell and alarm systems, not to exceed 150 volts when installed as specified by the National Electrical Code® (NEC) and other applicable standards. Thermostat wire is sunlight resistant.
What is 18 AWG wire used for?
18-gauge are used for low-voltage lighting and lamp cords in 10 amps. 16-gauge are used for light-duty extension cords supporting 13 amps. 14-gauge are usedfor light fixtures, lamps, lighting circuits with 15 amps.
What can I do with 18 gauge wire?
18 gauge jewelry wire is used for making sturdy clasps, jump rings and other findings. Solid (not plated or filled) 18-gauge wire can be used to make rivets.
How do you wire a thermostat?
Twist the wires to the connectors on the back of the thermostat or follow the directions provided with the manufacturer’s instructions. Attach the thermostat face to the new wall plate. Push all wires back into the wall, and slide the plate onto the wall plate.
What is the wire gauge for a thermostat connection?
18 gauge thermostat wire is recommended for any distances up to 250 feet. For shorter runs use 20 gauge . A thermostat wire uses low voltage signals to transfer data.
What is a thermostat cable?
A thermostat cable is used regularly in the installation of building climate control systems. The number of thermostat cables and their length per system depends on the type and complexity of the system.
