Wiring new outlets in the middle of the wire run

Hi!

me again. When wiring outlets in the middle of the wire run, should I be connecting and extending all three: Black , white and Ground like the picture below, or is it okay to just connect and extend the ground and to put both White and the both black wires on the outlet itself?

Either way is fine.
Pigtail method is more reliable, but takes more look and more time.

On the second picture, ground needs to be connected together. Since there is only one screw for ground, you will have to pigtail or twist and crimp the wire.

Something like below image.

To be clear, the use of a crimp on the ground as pictured is not required, a wirenut can be used to add a pigtail.

Thanks! I've been using wire nuts on the ground. All I want to know if it's okay to not do that for all black and white, but two directly attached each set to the outlet. It's a lot less work for me, but is it okay? In terms of codes, Maybe?

Yes it is ok and it is done all the time.
The only time I pigtail is if there are more than 3 wires in the box.
There also is a special ground wire nut, which as a hole on the top to allow one ground wire to pass through wire nutting other ground wires.



Not very cost effective for a large installation, but might be handy for home owners.

I like crimping better because it is very cheap and saves space in the junction box.

Greenies do not require any special tools like the crimp making them ideal for DIY applications.

Simply twisting ground wires is not good enough.

If the entering (feeding) and continuing hot wires are wire nutted directly to each other (with a pigtail to the receptacle, etc.) then the corresponding neutral wires must be similarly connected, directly to each other.

Neutrals are only required to be pigtailed on multiwire branch circuits. They cannot depend on the device for the splice.
