Question Crimp vs. wire nuts

Would someone please explain about the proper way to pigtail grounding wires? I'm confused about crimping vs. red wire nuts vs. green with wire coming out top? Is it legal to just crimp - seems better than putting on an extra large wire nut to further crowd a box, but then what about the sharp edges of the crimped wire?

Well for one, the green with the wire is only to be used on a ground. Always . After that, the nuts or crimping are both secure if done right .

some places may require the crimp , if you do crimp use the proper crimp tool rather than pliers

Any of those are allowed for ground wires.

Mass: Green or clear crimp ONLY.

They all are rated, but thats the way it is.

Make the connections good and secure, then use the..............

Grounds are VERY important.

Crimps are a cheap way to make up grounds. They are also a major pain if future work requires installing another box (like a larger one).

I prefer the green wire nuts for boxes that have only a few ground wires and I use the push-in type connectors for boxes where there are more than 4 or 5 wires. Before the flaming starts, I would add that I've used around 20,000 of these without a failure and have witnessed them surviving full circuit fault current with no apparent damage. They also have the advantage of not needing the care necessary to use wire nuts.
