What size wire do I need to run from furnace to thermostat?
Feb 25, 2020 · The Nest thermostat requires wires between 22 and 18-gauge, which is standard for residential heating and cooling systems. Anything smaller than 22-gauge wire could be too thin for the Nest thermostat to detect. Click to see full answer.
Can I add a wire to the thermostat?
May 23, 2020 · The Nest thermostat requires wires between 22 and 18-gauge, which is standard for residential heating and cooling systems. Anything smaller than 22-gauge wire could be too thin for the Nest thermostat to detect.
What is a C wire on a smart thermostat?
Can you use 22 gauge wire for a thermostat? Nest thermostats require wires between 18 and 22 gauge, which is standard for residential heating and cooling systems. Anything smaller than 22-gauge wire could be too thin for a Nest thermostat to detect.
What color are thermostat wires usually?
Nov 10, 2019 · A thermostat wire uses low voltage signals to transfer data. Over a long distance, the signals can become to weak to get a reading. How many volts can 22 gauge wire handle? The maximum amperage for a 22-gauge wire is . 92 amps for power transmission, according to the Handbook of Electronic Tables and Formulas for American Wire Gauge.
What gauge wire do you use for thermostats?
18 gaugeThe 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.
What can 22 gauge wire be used for?
Here at SparkFun, we typically use 22 AWG wire for prototyping and breadboarding. When using a breadboard or PCB, solid core is perfect because it fits nicely into the holes. For other prototyping/building involving soldering, the stranded core is #1, just be sure not to let too much current run through a single wire.
How many amps can 22 gauge wire handle?
.92 ampsThe maximum amperage for a 22-gauge wire is . 92 amps for power transmission, according to the Handbook of Electronic Tables and Formulas for American Wire Gauge. For amperage higher than . 92 you will require a lower-gauge, or thicker, wire.
Can telephone wire be used as thermostat wire?
Phone wire would probably work fine in most millivolt situations, but some thermostat wire has decent current going through it (like 24V control loops), so - as always - why not use the right stuff. It might leak more current and not complete the circuit in long runs.Mar 23, 2020
What is the difference between 22 and 24 gauge wire?
A 24 AWG wire has a diameter of . 0201 inch, and a 22 AWG wire has a diameter of . 0253 inch.
What does 22 AWG stand for?
AWG or American Wire Gauge is the US standard measure for the diameter of electrical conductors.

Can 22 gauge wire handle 24 volts?
As long as your device pulls 600mA or less, 22 gauge wire should be sufficient. If it needs current in the 2 amp range, you'll need 18 gauge wire.Oct 13, 2013

Can I use stranded wire for thermostat?
Nest thermostats don't support stranded wires, they require solid-core copper wires.
Can you use cat5 for thermostat?
Ethernet cable should work fine since thermostats use low voltage and low current. For simplicity, it's probably easier to use each pair as if it were a single wire.Mar 28, 2020
How many amps can thermostat wire handle?
The thermostat wire is sized for mechanical durability, not for current carrying capacity. Codes may require the circuit to be Class 2, 30 volts and 100 VA maximum, usually 24 volts and no more than 4 amps. It could be much less than 4 amps and most of the capacity may be required for the relays in the HVAC unit.Oct 5, 2016
