Technically speaking, power flows from the R (red) wire, but not continuously (not on its own, anyway). To make it continuous requires a common wire to complete the circuit. When the circuit is complete, 24V energy will flow continuously.The C wire (common wire) powers a smart thermostat by providing a constant flow of 24 VAC (volts AC). The term "constant flow" is the key here, because the C wire isn't the source of power. The R wires are the actual source of power, but they are not continuous, hence the use of the C wire. However, not all home wiring consists of a C wire. free background search What is a Thermostat C Wire? The C wire is an extra wire that is used to create a continuous 24V power loop between your thermostat and the rest of the HVAC system. It allows the power to be used for any application and allows more advanced thermostats to function to their highest potential. C stands for common and it's usually labeled as C.The dark-colored terminal is the common terminal and brings power from the source to the light fixture. As with single-pole switches, neutral wires do not connect to three-way switches. When replacing a three-way switch, the wire connected to the common terminal on the old switch must be connected to the common terminal on the … how to clear cache and cookies Remember, of all the common wire colors black wires are almost always hot.
