You mean you can't put one wire in each of the holes on the back and another one wrapped around the screw?:)

Had to back the screw out a tad to get both back and front wires. BTW, those are #12.


... I have not yet seen a crimp connector that naturally fit under the screws; some modification or extreme deformation seems necessary.
The right size helps. Not the wire end... the terminal end. I'm fairly certain the screws are #8. The terminal end in picture would accommodate a #10. "They" do make different size terminal ends.

...however the other style where you wrap the wire can only have one per screw.
No loops... :p

Clockwise?

No. When I went to pull the outlet out one wire came off. I wasn't going to put it back like that, so it took longer than expected to fix a problem. All I wanted to do was look in the box.

Hope this was a 22.5 CUIN box!

OK guys . . . we're going a little astray here. I think Dennis covered it earlier. Wirenutting the neutrals and a single white to the Duplex Receptacle and whatever is provided for the blacks - be it 2 screws, pressure plates or back stabs.
The positive leads do not have to be wirenutted. Thanks for the comments KO

The neutral only has to be pigtailed when it is part of a mutli-wire branch circuit.

Question on interpretation...

Where a multiwire branch circuit has split off to a two-wire portion of the circuit, can the grounded conductor be connected through a receptacle's terminal(s)?

Reliability of push-ins?

Reliability of push-ins?

From an efficiency point of view using the push-ins should save time.
What are your opinions about the reliability of using the push-ins? And if it is used as a feed through device which carries the load of the down stream devices?
Even though they are UL listed but would the push-ins be prone to the possibility of more failures?
