Typically the red and white wire of the 3-wire cable are used as the Traveler pair or wires which are connected to the two brass terminal screws at the other end of the 3-way switches. Identify the power source and connect it to the Dark Point Screw, or the Single screw at one end of the 3-way switch at the first switch location.Ī 3-wire cable with a ground wire is installed between the two 3-way switches which provides the switching between the two switches and returns power back to the first 3way light switch. The power source will enter at either the light fixture or at one of the switch boxes. Without a switch-wiring-diagram it can be very easy to make a serious mistake that will cause the circuit to malfunction and possibly become a hazard.The power can start at a fixture or either of the two switches.There are many ways to wire a 3-Way Switch.This is a common configuration in hallways and staircases.3-Way Switches are typically used to control one or more fixtures from two different locations.Materials: Make sure the replacement light switch has the same amperage and voltage rating as the original switch, and is fully compatible with the electrical circuit, the light fixture and the type of light bulbs being used. Notice: Installing additional fixture wiring should be done according to local and national electrical codes with a permit and be inspected. Precaution: Identify the light circuit, turn it OFF and Tag it with a Note before working with the wiring. Tools Required: Basic Electricians Pouch Hand Tools and Voltage Tester.Įstimated Time: Depends on personal level experience and ability to work with tools. Thanks for your electrical wiring question Ted. This electrical wiring question came from: Ted, a Homeowner from Baton Rouge, LA. What’s the solution for me to be able to turn on at the original end, where the switch is at the On position already?.I can turn it back on where I turned it Off.If I turn on the light at one end of the hall, then turn it off at the other end, I cannot turn the light back on at the other end, where the switch is already in the On position.You can turn on the lights at either end separately.I have two 3way switches in the hallway.Electrical Question: I have a problem wiring the 3way switches in my hallway.
