Review Of 3 Way Light Switch Black Wire On Silver Screw Ideas. Web where does the black wire go on a three way switch. Web going out of both boxes and into your light fixture will be 14/3 wire, which has a black wire (hot), a white wire (neutral), a red wire (traveler), and a bare copper wire (ground).

Web label the black live or load wire which connects to the power or the device and usually on the down position of the switch. Is there a methodical way for me to identify which wires represent which piece of the system so i can correct the bad wiring? This wire must be connected to the dark colored screw on the new switch.
