I'm in U.S. Info's probably out there somewhere but haven't found it, all i can find is how to wire one 3-way switch lol

I'm just running the wires and making the connections, before i connect to the panel, my father's an electrician and is gonna come out to make sure i got it all set up right and correct any mistakes i made. I'm more experienced adding 2 wire outlets and such lol. I'm getting confused on using 14-2 and 14-3 for the switches. I know the 3 wire comon connects the two switches. but how do you set it up for two seperate switches/gangs next to each other powered by the same circuit? One side will turn on the rec room lights and one side the laundry lights. The second 3-way switches will be at the bottom of the stairs, before the lights.

A basic wiring diagram would be great, can find them all over for wiring one light but not controlling separate lights lol!

Here are a few diagrams. Google Image Result for https://www.familyhandyman.com/wp-content/uploads/2018/04/how-to-wire-3-way-switch-1.jpg?fit=696,740

It all depends on where the power is coming into the circuit in relation to the switches and lights. There are several ways to wire them, the easiest to describe is power coming into one switch and then the next switch with the load (light or outlet) fed from the second switch. Look at the diagrams and if you still have questions post back in this thread.

Sorry if i wasn't clear, I don't know the proper lingo lol! To clarify, I'm wiring 2, 3-way switches next to each other, they are going to be on the same 15A circuit, but they are switching 2 different rooms. so 2 switches at the top of the stairs, 1 wil switch the rec room, one will switch the laundry. The other 2 3 way switches will be at the bottom in the respective rooms. I know there's a difference in wiring based on where the switches are in line from the lights; It'll be like in the diagram you provided, switch, switch, light

So if i understand this correctly, I would just hook everything up like in the diagaram you provided, except i would pigtail the common black wire to power both switches? And then you wire all 3 neutrals together?

If I understand you correctly then yes, you take the hot incoming power, pigtail and run one pigtail to each of the 3 way "common" screws. Then you wire nut the three neutrals. BUT, you only wire nut the three neutrals together if and only if they are being powered by the same circuit which you state is the way it is being wired.

If he's using a common hot, he needs to use the common neutral.
