In this basic 4 way light circuit the source is at the first switch and the hot connects to the common on that switch. Three-wire cable runs between all the switches and the traveler wires are connected between the two 3-ways and the 4-way. Two-wire cable runs from the last switch to the light fixture and the common on that switch connects to the hot terminal on the light.
A 3-wire cable runs from L1 to L2, 2-wire cable runs from there to the first switch, and 3-wire cable runs between SW1 and SW2. The source hot is spliced to the black wire running between the lights and at the last light, it is spliced to the black wire running through to the common on SW1. The white wire is marked black and spliced to the black wire running to the common on SW2.
This arrangement makes it possible to power the heating elements in the appliance using the two 120 volts combined and one 120 volt wire to power timers and lights. This circuit is still used for clothes dryers but not for most new installations of kitchen ranges, for that a 50 amp circuit (pictured below) is now used.
At the lights the hot source is spliced to the black wire at each fixture box, at the last fixture it is spliced to the black wire running to the common on SW1. The neutral from the source is connected to each light fixture with a pigtail and run on to the next light.
