How to reconnect the outlet

receptacle

I took apart an outlet for doing some drywall work. I have an outlet that has two black, two white and I believe four grounds. This is where I am confused. One ground should go to receptacle. Should it not? Or do I take the green screw in back of the box and run it into the wire nut with other two ground wires?

Best Answer

Four ground wires.

  • One to the upstream supply (along with a black and white)
  • One to the downstream load (along with a black and white)
  • One to the steel box
  • One to the receptacle

Works for me.
