Help Please! This is the first time I am attempting any electrical project. I changed out old receptacles with new ones in our master bedroom. I used Leviton standard outlets 15A-125V.
Question #1: How come some of the receptacles have 2 white, 2 black and one ground wire, while others have only 1 white and one black wire?
Question #2: The switch to the bedroom controls the ceiling light and the bottom plug of the outlet next to the bed. Now that the new outlet is installed, the switch no longer controls the bottom plug, Why? I wired it exactly like the old one. I did not do any work on the switch. Please help me understand!
