The neutral wire provides a return path for the circuit and the ground wire provides extra protection from electrocution not found on older 30 amp, 240 volt appliance hookups.
At SW1 the white wire is wrapped with black tape and run through to the common on SW2 using the white wire at each switch. At the lights the white wire from SW2 is spliced to the hot terminal on each fixture. The black and red wires running between the switches serve as the travelers for the circuit. At the 4 way the travelers from SW1 connect to T1 and T2 connect to the travelers for SW2.
The diagrams on this page illustrate connecting multiple lights in 3 way and 4 way switch circuits. Check below for more details about these circuits and some troubleshooting tips.
In order for a 4 way circuit to work, the 3 way switches must be wired properly at the the beginning and end of the path. So be sure that the common terminal on one of the 3 ways is wired to the hot source, and the common on the second 3 way is wired to the the hot terminal on the lights.
