This represents a change in the NEC code that requires a neutral wire in most new switch boxes. If you are running a new circuit check the electrical code to understand this and any other updates to the required procedure.
The following 3 diagrams show the wiring for a specially made dimmer that can be used in these circuits in place of either of the the 3 way switches, or both. This arrangement allows for lowering the lights in a 3 way circuit. After the dimmer level has been set the other switch will turn the lights off and on at that level. This device can be used in place of any of the 3 way switches in these circuits, as well as to dim the lights in a 4 way circuit.
The 4 way comes right after the light fixture, but before the second 3 way switch, making it fall between the two 3 ways as needed. It could also be installed on the other side of the light and the effect would be the same.
This diagram shows the first wiring option for this device. In this arrangement the connecting tab between the hot terminals remains intact. The source is at the device and the hot is connected directly to one of the hot terminals, it doesn’t matter which one.
There are two sets of terminals on a ground fault circuit interrupter (gfci) receptacle: the line terminals and the load terminals. The source from the circuit should be connected to the line terminals and any standard duplex outlet or other device connected to the load terminals will be protected by this gfci.
In this updated diagram 3-conductor cable runs between the receptacle and switch, and the red cable wire is used to carry the hot source to the bottom terminal on the switch. The neutral from the source is passed through to the switch box using the white wire and in this diagram the white wire is capped with a wire nut.
Here two 3 way switches control a wall receptacle that may be used to control a lamp from two entrances to a room. This circuit is wired the same way as the 3 way lights at this link.
This drawing shows the wiring for multiple lights in a 4 way circuit with the source and fixtures coming before the switches. More lights can be added to this circuit by duplicating the wiring shown here for each additional fixture. Here 3-wire cable runs between L1 and L2, 2-wire cable runs from the last fixture to SW1, and 3-wires runs between SW1 and SW2.
