I’m adding a light to my closet. It will be operated by a switch. Currently, I only have a receptacle next to the closet. The light switch will be directly above the current receptacle. Currently, there’s a romex wire coming down from the attic that goes to the receptacle and there’s a romex wire that comes from the receptacle and continues along the circuit.
I know that I can run a wire from the receptacle to the light switch for power. This would be illustrated in the bottom right of my drawing. But out of curiosity, I’m wondering if it’s possible to run the wire that’s coming from the attic into my light switch box, use it as a source for my closet light, and continue uninterrupted power down to the receptacle. This would be illustrated in the bottom left of my drawing.
