I have a 4 season room with a new light. I ran a wire from this light to a 2-gang box in the room, and ran a romex wire from this new box to an existing box in the kitchen (they are on the opposite sides of the same wall), and I'm trying to power the new light switch off existing power coming into the kitchen box.
I am using Legrand Adorne paddle switches, and wonder if I can use the switch in my diagram. On the current switch, A1 is connected to HOT and B1 is connected to 1-POLE. I originally tried to follow this diagram but it did not work as expected. Thanks in advance!
