What is the most common color of electrical wire?
Three-way and four-way switches operate a single appliance from multiple locations and use traveler wires to connect the switches. Blue and yellow are considered the most common travel wire colors, ...
What is the red wire used for?
Red wires can also be used in some 120-volt applications. Like black wires, red wires can be used as switch legs. Dawson notes that red wires are commonly used when installing ceiling fans that use separate switches for the fan motor and light. When this is the case, the hot black wire is connected to one switch to operate the fan motor, ...
What is black wire?
Black wires are “hot” wires, which means they carry a live current from your electrical panel to the destination. They feed electricity to electrical outlets, switches and appliances from the home’s main power supply. Black wires can also be used as “switch legs” that connect wall switches outlets and appliances (like ceiling fans or lights), ...
What is the red wire on a smoke alarm?
Red wires are also used as “trigger wires” for interconnected smoke alarms. In this case, the red trigger wires allow all the interconnected alarms to go off simultaneously when one alarm is triggered. Orange wire may be used in place of red for all of these purposes. 4 / 5. 66North/Getty Images.
What does gray mean on a wire?
White and Gray. “White or gray indicates a neutral wire ,” Dawson says. A neutral wire returns electricity from the hot wire back to a grounded portion of the home’s electrical panel to complete the circuit. Without it, the electrical current couldn’t circulate and the live wire couldn’t provide usable power.
What color wire is used for grounding?
