Where do you connect the C wire?
On the C-Wire Adapter’s “Equipment” side, connect the wires to the corresponding terminals on the control board. Note: Be sure to remove the plastic tip on each wire before connecting to a terminal. Use the included mount and adhesive pad to attach the C-Wire Adapter inside your furnace or heating system.
Where does the C wire get its power?
WHAT IS A C-WIRE? A C-wire, or a common wire, runs from your low voltage heating system (24v) and carries continuous power to your thermostat. In today’s electric market, most newer heating and cooling systems have C-wires, which guarantees compatibility for the installation of all smart thermostats.
Can I connect C wire to ground?
Wiring to the ground @ any outlet would potentially work, but is not good practice,as many things could go wrong and possibly short or overload the circuits in your furnace controls, not good! Happy trails. Hello, and welcome to Home Improvement. Thanks for the answer; keep ’em coming.

Do you need C wire for Nest?
With a Nest Thermostat E or Nest Learning Thermostat, you’ll need to install a C wire if the thermostat has power issues or its battery often drains.
What if there is no C wire for thermostat?
You most likely have a line voltage system and none of the popular smart thermostats on the market are available to you as-is. (There is some hope with an adapter, but don’t get too excited yet.) This wiring indicates a line voltage system, and you’ll need an adapter or a smart thermostat designed for line voltage.
How many wires can be connected to the C terminal at the furnace?
Two wires per terminal in HVAC work is common (though not usually correct), while 3 or more will tend to use a pigtail.
Is the C wire hot?
Typically, the wires that provide the power (often called the “hot” wires) are labeled Rc (cooling) and Rh (heating).
Can I jump R to C wire?
C is a common neutral wire. You can’t jump it from Rh as that is a 24v wire. You need a third wire, C, to return to the unit and hook to the common side of the transformer. For ease of thought, think of R as “hot” and C as “ground”.
Is RC and C wire the same?
The C and Rc wires are not the same. To install this thermostat you should follow the exact same wiring of the previous thermostat.
Can I use G wire for C wire?
Option #3: Use a G-Wire as a C-Wire
If there is no hidden C-wire, you can use a G-wire instead. However, you will not be able to use your fan independently when the heating or cooling isn’t running. Also, many HVAC systems are incompatible with this solution, including: HVAC systems using electric heat.
What color is the C wire?
Blue wires
Blue wires are also called “C” wires because they are the Common wire. C wires are necessary for any “smart” thermostat that needs to be connected to a power source 24/7, regardless of your heat pump type.

How many wires are needed for a smart thermostat?
4 Wire
4 Wire Thermostat Wiring (Heat Pumps, HVAC)
Smart thermostats like Nest and Ecobee thermostats require 4 wire thermostat wiring to function properly. In addition to heating (2 wire thermostats) and C or fan (3 wire thermostats), 4 wire thermostats include the cooling wire, usually in blue or yellow color.
How do I power a nest without a C wire?
Quote from the video:
Quote from Youtube video: For the common wire. So what you would do is go to your nest thermostat. Take off the G wire. Usually. It's going to be the green wire going to G. So you press on it you pull it out and before.
