How a 3 way switch is wired?
Three-way wire(which includes red, black and white wires) runs from the switch on the left to the switch on the right, with the white wire carrying ground and the red and black wires carrying the output from terminals in the left switch. Normal sheathed cable runs from the right switch to the light.
Is the common wire on a 3 way switch always hot?
Wiring for a 3-Way Switch The most important wire to get right is the one connected to each switch’s common screw terminal. This is the “hot” wire (usually colored black, but not always), and it brings the power from the source and delivers it from one switch to the next and to the light fixture.
