I want to put an outside GFCI and was wondering if I could pull power from the switch. The switch has three light switches. It is 14-2 wiring and I checked that there is power coming in and three blacks are wire nutted together leading to the individual switches. Can I pigtail off those and run down the wall to my GFCI I plan on installing? Also, I do have the white neutral wires that are all wire nutted together.
