Seeing the "House next door" post, I would like to say one should remove the jacket fron NM cables prior to insertion into the box. This permits visual inspection of the insulation for damage. I know the "new breed" method is to stuff the whole cable in and stick a utility knife up into the box and score the jacket then pull it off. I have debated this with several young residential guys. I have also seen slits in the insulation perfectly in line with the jacket line. The last time, I experienced a short while adjusting a receptacle. Guess what the cause was? I now insist that anyone who works with me prep the cable beforehand. I will not live with the question of whether or not my wires are sizzling behind someones bedroom wall.
The only problem that I would have with this is the fact that you need the jacket in the "clip" or squeeze connector to be code compliant. Otherwise I like the concept and if you take a little time, you could strip the jacket just right to work with the "clip".
I also install receptacles with the ground up, but sorry, I don't pre-twist.
The klein 1412 romex tool is a must have for residential. This tool will pay for itself real fast.
I always remove the sheath before landing in the box for wire inspection and arrangement purposes.
I also arrange my conductors beforehand so they line up nice once landed inside the box (whites next to whites, blacks next to blacks.....) I usually have to flip the romex somewhere before it enters the box to accomplish this but you'll never see that once the walls are closed.
I strip the jacket, twist the bare grounds and install a "greenie" and roll up the wires real good and as far back in the box as possible to avoid the rotozip bit. When it's time for pluggin' and switchin' it goes real fast. If it's a GFCI that feeds down stream receptacles I strip about 1/2" off of the ends of the "line" pair in the box. I do the same thing to the home run in the first receptacle box it hits. I also mark the floor in front of the home run boxes with red paint in case the GC needs an outlet heated up early for lights or a heater to help dry the mud.
Redsy & all: I hate to rain on the parade of the "new breed", but they would not pass a "rough" inspection here. RX sheath has to be off, grounds spliced thru w/tail. The other "splices & tails" are optional, unless it's a multi-wire circuit.
BTW guys, I'm with you...my guys make up all the splices/tails for rough. We do the paint on the floor thing too.
Hotline, I think you missunderstand what the "new breed" does. They push the RX in the box, then take a box cutter and score the sheathing, pull off the sheathing and make the taps as normal. So the box is ready to go for rough inspection.
I resisted this "style" of wiring for a long time, but now have move to the dark side myself. This is now the method we encourage. We have seen too much damage from prestripping the old way by twisting the wire in your strippers. On several occassions we had new helpers completely cut through a conductor or 2. The new method does not harm the conductors or inner sheathing.
Pretwist if 3 or more wires, ground down.

Gotta go with eagle on this one. All cables in the box first, stapled up and then stripped. I check all the time to make sure NO conductors are nicked. Had a guy back in 98 screw up some wires with one of those klein romex strippers. Ever since i have not allowed those things on the job. We pulled 19K ft of 12/2 since March 10th. Speed does count but a safe installation is top priority.
More than two wires - pre twist. Grounds down... (unless specs call for grounds up)
