The electrical line passes through and flipping the switch either connects or disconnects the flow of current. With a pair of 3 way switches either can make or break the connection that completes the circuit to the light.
Tutorial 3 Way Switches And 4 Way Switches
3 lights 3 switches 1 circuit. Above the last switch in the circuit switch 3 in this article make a small cut where the wall and ceiling meet to make threading the cable to the fixture easier. You have 2400 watts available to you on a 20 amp branch circuit. By rule of thumb you would stick with 8 to 10 outlets and or lights per breaker. Lastly run a length of 2 wire romex from the second 3 way switch to the ceiling light.

If there are 3 devices of 400 watts connected to the circuit already then it leaves 240 watts to be used by the new lights. If one switch is up and one is down the current reaches a dead end no current flows and the bulb is off top left and bottom. Be sure you stay within those limits with your lighting. At the first 3 way switch where the wires are coming from the panel run a length of the 3 wire romex to the 4 way switch location. Electrical house wiring diagram.
Step 2 remove the baseboards along the path from the power source receptacle to each of the switches. It is true that there are several wiring configurations for wiring 3 way light switches and all of the wiring configurations will depend on where the incoming circuit power is located and once that is identified the rest of the three way wiring connections are straight forward. Take a note of all the devices in the circuit and calculate the total electric energy requirement. First lets take a look at the back of several different light switches. Just add all the maximum fixture wattage ratings together. Now this is of course they are 120 volts 60mhz usa or canada.
When both switches are down the circuit is complete bottom right. 3 way switch diagrams for multiple light fixtures. Wiring a 3 way light switch.
