The travelers get connected to the two brass screw terminals on the 3 way switch. The white wire has been taped with blue electrical tape to show that it is not a neutral conductor but a traveler.
Making A 3 Way Light Switch To Single Pole Switch For Smart
3 way switch wiring red black white. The white wires connect to each other and nothing else. The ground wire also connects to the switch but the white wire gets spliced to the circuit neutral wire and bypasses the switch. The black hot wire in the electrical box above is connected at the other end to the black line wire and gets connected to the black or red screw on the 3 way switch. Wiring a three way switch. Take the red from the three wire and put it under one. Black wire power or hot wire white wire neutral bare copper ground.
This is a typical wiring setup for a 3 way light switch with black white red and ground wires. The same wiring method is also used for two way switch wiring. The two same screws get the black and red wires from the other cable. Connect the black wire to the other brass screw. If you dont have a ground wire leave the green screw unconnected. The standard way to power a split tab outlet is to run a three conductor cable to a wall switch.
When wiring a 3 way switch circuit all we want to do is to control the black wire hot wire to turn on and off the load from 2 different locations. The bare wires attach to a little bit of wire that connects to the green screw on the switch. Red wire power or hot wire black wire power or hot wire white wire neutral bare copper ground. The red wire is the other traveler. If that is the case pigtail the blacks from the two 2 wires together and place the pigtail on the black or common screw of the 3 way switch. If you have a ground wire connect the ground wire to the green screw.
The different screw gets the black wire that comes from the cable with the black white and bare wires. The cable has a black wire which connects directly to the circuit and a red wire which connects to the switch.
