I got a Kasa Smart WI-Fi Power Outlet for Christmas and want to replace an outlet in my living room with this. The Smart Outlet has one White, one Black and one Green wire coming out of it and no other places to connect wires. When I pulled the outlet out from the wall, there were three black, three white and a copper wire connected to it. What is the reason for three wires?
Based on my research I should tie all three black and all three white wires into a pigtail with the wire from the smart outlet and wire nut them together, then do the copper to the green. Is this correct?
