Looping the wire under the screw isn't forbidden. It's a pain in the butt for the next guy who comes along sometimes.

I disagree with the first response; NEC 300.14 states that there shall be at least 6" pulled into the box, with at least 3" extending out of the box, so unless the device was installed with the necessary amount of conductor before the wire was stripped, the install is not code compliant. With that being said, probably not an unsafe termination, but I would pigtail out to any new devices installed. There was a discussion on this forum in regards to this issue, if you want some other opinions.

Here is a link that might be useful: Help with wire 'looping' inside a box

Ah, that is a different issue than the "looping" one. There IS nothing wrong with the looping. If there really is only 2" of wire free inside the box, you've got problems on the other front.

The other thread doesn't provide any compelling evidence that looping is not permitted by the code.

That code reference was the best I could come up with as far as a violation, b/c when I've come across this, the wire is invariably too short; I wind up having to tape the stripped part with some Super 33 and pigtail out. I agree with manhattan42- devices shall be installed per the manufacturer's instructions, and the termination points are exactly that- the wire terminates at that point. Just my interpretation. Also, when devices need to be changed or replaced, the task tends to be more involved, whereas with pigtailling, much easier. However, I do go through lug terminations on tasks such as landing a grounding electrode conductor or equipment grounding conductor, but that's not quite the same thing.
