First lets take a look at the back of several different light switches. Take a note of all the devices in the circuit and calculate the total electric energy requirement.
Tutorial 3 Way Switches And 4 Way Switches
3 lights 3 switches 1 circuit. Wiring a 3 way light switch. Step 2 remove the baseboards along the path from the power source receptacle to each of the switches. A simple ordinary on off light switch as in the first photo has two screws on it. Be sure you stay within those limits with your lighting. You have 2400 watts available to you on a 20 amp branch circuit. Now this is of course they are 120 volts 60mhz usa or canada.
The switches must create a complete circuit for current to flow and the bulb to light. In this circuit two light fixtures are shown but more can be added by duplicating the wiring arrangement between the fixtures for each additional 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. 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. By rule of thumb you would stick with 8 to 10 outlets and or lights per breaker.
When both switches are down the circuit is complete bottom right. With a pair of 3 way switches either can make or break the connection that completes the circuit to the light. Here the source is at the first switch sw1 and 3 wire cable runs from there to the first light l1. 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. However wiring three switches to control one light is possible. Now run another length of 3 wire romex from the 4 way switch location to the second 3 way switch location.
3 way switch diagrams for multiple light fixtures. Now find all the appliances and other lights that are connected to that circuit.

Wiring a 3 way switch with multiple lights. Lastly run a length of 2 wire romex from the second 3 way switch to the ceiling light. The electrical line passes through and flipping the switch either connects or disconnects the flow of current.
Just add all the maximum fixture wattage ratings together. When both switches are up the circuit is complete top right. 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. A diagram is difficult with out more detail all the switches in one 3 gang box or are they in different locations. 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.
