I tied the reds to each other and the blacks to each other and then tested the light with only two 3 way dumb switches on it it worked. Well cover the easier scenario first.
How To Convert A Regular Switched Circuit To A 3 Way One
What is the red wire in a 3 way switch. When you see a red wire in a light switch box it can mean two things. The red and black wires were connected to the 4 way switches and the whites tied together. Keep in mind that the traveler terminals for red black wires are universal and will work regardless of which one the traveler wire is connected to. Replace any regular switches with the 3 way switches. With nm cable the wire colors for travelers will be black and red using 3 wire cable. The cable run linking the two switches is made with 3 wire cable.
The three way switch is a variation of the standard single pole switch which controls a light only from one locationa third type is the four way switch which is used in conjunction with two three way switches to control lighting from more than two locationsthis configuration may be used in open plan homes or in large kitchens or great rooms where a central bank of lighting fixtures might. The black hot wire connects to the far right switchs common terminal. Red black white wires. Red wire power or hot wire black wire power or hot wire white wire neutral bare copper ground 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 grounding wire is connected both to the switch using a pigtail wire and to the second cable run passing onward to the next switch. Or it could be the red wire is the wire going to the fixture and the black wires are the live wires.
The colors will vary depending on whether nm cable or conduit was used. All home electrical wires made in the us. With conduit the wire colors for travelers could be any color. It could be there is or once was a three way switch in play. Red and blue wires link traveler terminals of both switches. If the switch box is metal it also must be pigtailed to the grounding wires.
A 3 way switch will not have the words on or off written on it. There is no standard for wire colors on 3 way switch travelers. Follow standard color codes that identify each wires function in a circuit. The red wire which is connected to the first switchs common terminal leads back to the fixture. Traveler wire terminals these are located on each side of the switch towards the top of the switch. Before you start installing take a look at your new 3 way switch to identify all of the terminals that you will be connecting wires to.
Knowing which wire does what and goes where is imperative not only in the correct configuration of an electrical system but also for your familys safety. The black and red wires are travelers and are connected to the traveler screw terminals on the two switches. I replaced one 3 way with the smart switch and saw the exact same behavior as posted above. C now connect the traveler red black wires from the new 3 wire romex cable to the two traveler terminals at the top of 3 way switch 1 the first switch.
