Does it matter where the traveler wires go on a 3 way switch?

The traveler wires run between the two 3-way switches, offering two potential pathways to complete the circuit and send power onward to the light fixture. It makes no difference which traveler wire goes to which traveler terminal on the switch; the traveler terminals are interchangeable.

Where does the red wire go on a 3-way switch?

The black hot wire connects to the far right switch’s common terminal. Red and blue wires link traveler terminals of both switches. The red wire, which is connected to the first switch’s common terminal, leads back to the fixture.

Which of the brass-colored screws a traveler wire connect to does not matter.

How to troubleshoot 3-way switches?

[Solution] How to Troubleshoot a 3 Way Switch TURN OFF THE POWER AT THE CIRCUIT BREAKER Remove the 3 wires from each of the switches and make sure that none are touching anything. IN THIS STEP YOU WILL BE TURNING THE POWER BACK ON, DO NOT TOUCH ANY OF THE WIRES PREVIOUSLY REMOVED WITH ANYTHING BUT THE METER PROBES AS INSTRUCTED. At the switch where you found power in step 2, put the other 2 wires you removed from the switch together and wire nut them. See More….

What is an electrical wiring diagram?

A wiring diagram is a simple visual representation of the physical connections and physical layout of an electrical system or circuit. It shows how the electrical wires are interconnected and can also show where fixtures and components may be connected to the system.

What is a 3 way circuit?

A 3-way circuit is a lighting circuit that allows one light fixture to be controlled by two wall switches in different locations. Stairwells, hallways, and large rooms with multiple access are all candidates for 3-way circuits.
