Next lame electric question

13. If the box is grounded and it's metal, you don't need to fuss with the ground.

You can if you want or you are in doubt of good contact of the new receptacle “yoke” to the junction box.

But fussing with wires deep in those “handy boxes” sucks.

The receptacle will ground when mounted to the box. Assuming the box is set at the correct depth and not caked in paint.

I’m in Chicago. We don’t use ground wires at all as all our wire is in grounded EMT conduit/boxes. The conduit is the path to ground.

So that green screw gets automatically screwed down out of my way. You should remove the little cardboard squares that hold the screws in while in the package as that can interfere with ground - but it really doesn’t. I think code says at least one needs to be removed

Buy yourself a little receptacle tester. They are like $8 bucks. It will tell you the receptacle is wired properly and whether the receptacle is grounded or not.


Better yet, get a multimeter at check AC Voltage between hot to ground.
