I am installing multiple electrical outlets in a rec room using romex
and metal outlet boxes.
When I ground the boxes, do I need to make a 4 wire pigtail from the
incoming and outgoing romex, a wire off the grounding screw of the
receptacle, and a wire off of the grounding screw on the box?
Is this the proper procedure?
Thanks in advance for your help.
That is certainly *a* proper procedure. There are other ways to do it
that amount to the same thing; sometimes "real electricians" seem to
like to crimp ground wires together to save time. But this is the way
I'd do it, connecting everything together with a wire nut (probably a

Since this is a homeowner project and you want the easy way to go, get
a small bag (5) of the green wirenuts with the built in pigtail. Then
you loop the incoming wire under the box screw like RBM says and twist
up the incoming and outgoing ground under the greenie. The pigtail
goes to the receptacle. It is stranded so the device is easier to push

Yes, this is almost how I do them.
I get green wirenuts that have a hole in the end (greenies). Wrap the
incoming wire around the box screw, tighten screw. Take that same
wire and fasten the outgoing ground wire to it lower on the wire,
leaving 5 or 6 inches of bare wire. Attach the green wirenut where
the two are coming together. The long end goes thru that wirenut
hole, and goes to the outlet green screw. To do this, you need at
least 10" of cable stripped on the incoming wire (or the out going
one, it dont matter). I prefer 12" of wire. That way you have plenty
to work with.
This works well without a lot of excess wires filling the box.
There is a photo on this website:
Here's another site with a photo (the wire coming out the hole should
be longer than that shown in the photo. 4 or 5 inches is good. You
want the greenie buried in the box, not next to the outlet).

The advantage of the greenie with the built in pigtail for a
homeowner is you don't have to be as careful dressing the bare wire.
It is insulated with a spade terminal on the end. It is also stranded
so getting things back in the box is a little easier. For a few
outlets, the cost difference is insignificant. I can understand a pro
working to a bid on a hundred outlets will want the cheapest way that
is code compliant. In this case that would be a yellow wirenut with a
pigtail using scrap wire from the job.
