When the electrical source originates at a light fixture and it’s controlled from a remote location, a switch loop is used. The circuit pictured here is wired with 2-conductor cable running from the light to the switch location. The white cable wire in this switch loop is wrapped with black tape and connected to the bottom terminal on SW1 and the hot source at the light. The black wire is connected to the top terminal on SW1 and the hot terminal on the light fixture. The neutral from the source is connected directly to the neutral terminal on the light.
This diagram is the same as the one above but the dimmer comes first in the circuit. This arrangement is provided for easy reference when dealing with a circuit wired like this.
Source 1 comes in at the light fixture and a 3-wire cable is run from there to the switch half on the device. The hot from the source is spliced to the black wire and to the input side of the switch at the other end. The white neutral from the source is connected directly to the light fixture. The red wire from the switch output goes to the hot terminal on the light.
The common terminals will always be connected to a hot wire, either from the source or on the light fixture. These connections can be reversed if it’s more convenient, as long as one of the 3 way common terminals connects to the hot source and the other one connects to the hot on the load, these circuits will work properly.
