What color wires go on a switch?
Black wires are hot wires that run to the electrical outlet from the switch. Red wires are hot wires common in a 240-volt outlet or when a wall switch controls the outlet. Blue and yellow wires are hot wires for ceiling fans and three- or four-way switches. White or gray electrical wires are neutral wires.

What is the difference between 2 way and 3-way switch?
Much like the two-way switch, a three-way switch turns a light on or off. However, there is a crucial difference. The three-way switch is used in conjunction with another three-way switch. Each one of them has the power to interrupt the electrical flow and turn the light off from a different part of the room.
What is the red wire in a 3-way switch?
The black hot wire connects to the far right switch’s common terminal. Red and blue wires link traveler terminals of both switches. The red wire, which is connected to the first switch’s common terminal, leads back to the fixture.
Can red and black wires go together?
These wires are typically used for switch wiring as well as the interconnection between smoke detectors hard-wired into the power system. You can link two red wires together, or you can link a red wire to a black wire. Since red wires conduct current, they are considered hot.
Does the red wire connect to black or white?
Attach the black wire to the outlet you want to always be on (usually the top one) and the red wire to the switched outlet. Connect the white wire to either of the chrome screws (remember, they are still joined) and the ground wire to the green ground screw.
Which wire goes to black on 3-way switch?
Black wire: This is a hot wire that carries electricity from the power source to the first switch in a typical 3-way setup. It’s also called the “common wire” or the “line wire.” Unless the breaker is off, this black wire is always hot.
Which wire is hot when both are same color?
In most modern fixtures the neutral wire will be white and the hot wire is red or black. In some types of fixtures, both wires will be the same color. In this case, the neutral wire is always identified by some means. In some cases, there will be small writing on the wiring case.
Does it matter which wire goes where on a light switch?
It doesn’t matter as long as you do it the same on both switches. So, if you connect it to the upper right terminal on one switch, connect it to the upper right terminal on the other switch. Connect the second traveler wire to the terminal opposite the red wire terminal.
Where does the white wire go on a 3 way switch?
Three-way wire(which includes red, black and white wires) runs from the switch on the left to the switch on the right, with the white wire carrying ground and the red and black wires carrying the output from terminals in the left switch.
Where does the white wire go on a light switch?
A standard single pole light switch will simply require you to attach the black (load) wire into it, and then the black wire leaving the switch and to your lights. The switch serves to cut the power from reaching the light switch. The white or neutral wire bypasses the switch and goes straight to your lights.
What do you do with the red wire?
The exact purpose of a red wire for a light fixture can vary. Except in rare cases, it is a hot wire or a switched hot wire. Check the wire with a non-contact voltage tester with the power and switch turned on. If the tester indicates the wire is hot, turn the switch off and retest.
