Electrical – How to wire a 3 way switch with power feeds to another switch

electrical

I need help with the wiring for a 3 way switch in my hallway. One switch box has the power source coming in, the switch leg and 2 Power feeds going out to two other lights. One power feed supplies the hot for a closet switch in an adajencent room and the other power feed supplies the hot for another 3 way switch that controls a light in the stairwell.

I’m unsure how to wire the switches allowing the 3 way to work for the hallway and the other lights to work properly.

I have spent 3 days and many hours of frustration trying to work this out. Any advice would be greatly appreciated. A drawing would be wonderful.

To wire to other loads from the box with a 3-way switch and a line feed, you simply identify the line cable, that is, the black line hot (always hot) and its associated white neutral (both being in the same cable).

Then connect another cable to the line hot and neutral routing it to the location you want to power-- connecting black to black, white to white and gnd to gnd. If your current connections are with wire nuts you must unscrew the nut on the line connections, add the new wire and reconnect with the same wire nut or a larger one if necessary.
