Question

3 way switch wiring question


Hi

I have a question about 3 way switch. Most diagrams show that 2 14/2 wires are required between lights on a 3 way switch. I found this diagram but the website kind of looks sketchy.(I am not affiliated with it)

What do you guys think? Is this a safe diagram? I would rather use one 14/3 than 2 14/2s if possible.

Cheers

It will work but it has several code issues.
1. The switch on right is feeding the switched power to the light on the white. That is not allowed you must use the red or the black for that function.
2. Code in most locations currently requires a neutral wire in all switch boxes. The switch on the right does not have a neutral.
3. Single wires between lights(the extra black) are not allowed. You must use a 14/4 cable.

this will not be code compliant anymore you need to bring hot and neutral to first switch then take a 14/3 to the next switch (white neutral,black and red travelers) from this switch you take a 14/2 up to the light.

WHY must you run from switch to light to light to switch???
It is MUCH easier to run directly between the switches with 3-wire then up to the lights from one of them.

that is just one way of running the circuit back in the day everything went through the light box.

And that is one of the drawbacks of older houses. Too many switch loops and crowded fixture boxes.

thats why we have lots of nice service calls today the issue is the older wiring did not hold up well to the heat generated from the light fixture.

Well that's the question. Unfortunately the electrician that designed the wiring for my basement set it up that way. Even more unfortunately I proceeded to wire the lights that way as per the diagram.

I guess my best bet it to connect the wires in one of the lights as if the light doesn't exist and run a 14/2 from the other fixture to said light.

Does that sound reasonable?
