4 Way Wiring Diagram Neutral Switch 2 Lights. To me this wiring doesnt look right. You would just continue from one 3 way switch box with the 143 three conductor cable two colored traveler wires a white neutral and a bare or green ground wire.
The 4 black neutral wires are terminated into a choc block behind the switch. Each 3 way switch in these examples are controlling the power source to the same load. The white is also known as the neutral wire and this wire connects with the silver screw.
With 2 lights it is spliced with the white wire running to the switches.
It shows the components of the circuit as simplified shapes and the power and signal links in the midst of the devices. Here is a diagram of when power is coming to the 4 way switch first with multiple lights.
