Residential crimp-on ground sleeves

[supergeek]

Ok, admittedly, I'm pretty pathetic for not knowing the answer to this question, but here it is........ What's the deal with the short crimp-on ground sleeves used in house wiring? I'm from a commercial/industrial background and we always just use wirenuts. Is this a code requirement, or are they cheaper or faster or something? I don't have anything against them, it just seems like a lot of trouble to carry around the sleeves, the crimping tool, etc. Thanks!

For the same reason you also won't find too many spec grade receptacle outlets in residential jobs. Most devices you are going to come across in houses cost about .56 cents apiece. In the case of crimp tubes, speed is the key. I use the Thomas and Betts ones so that I can use the Thomas and Betts listed crimper, which is not that slow bulky 4 point thing that Buchannon lists for crimping its tubes. In a bit I will get called a hack, but once I twist up the grounds real quick,and then crimp on a tube its as fast as spinnning on a nut, and the connection is every bit as tight. Fire away, all you anti crimp tubers.

We use the Greenie wire nut with the hole in the end for the pigtail. I can't comment on the price comparison because we never use those crimps. I prefer a connection that is easily opened for additions or changes, which IMO a crimp is not.

Its mostly old school, I was taught to use sleeves which I call sta cons and crimp them with a sta con tool. I've seen all kinds and its mostly what you choose, most important is making a good connection no matter what you use. Semper Fi

I agree with the bold part here.

to throw in a monkeywrench to this thread, those crimps technically are not listed for grounding purposes...

Pierre,

Neither are wirenuts, except the green one. Just another example of stupid rules. The standard wire nut is suitable to supply the current into the fault, but not suitable to be part of the fault clearing path!!!

Hack...(had to do it)

I hate the things, but whatever floats your boat....

Grounds?

Why grounds?

The little crimpy thing-a-ma-jigger and a little tape for all connections!

First twist conductors until they look like they came from the factory looking like that.
Second crimp the little crimpy thing-a-ma-jigger
Third three rounds on Monkey Grip
Forth three rounds of the slick black tape
Done!

Used on all joints.

I used to carry around that darn fourway crimper but it takes too long...I'm interested in how much the T&B crimper and connectors cost...

Red Wirenuts and a make-up bit seem to be the quickest way of terminating ground wires, but people seem to think they arent intended to carry ground fault current..why not?

I use wire-nuts or Buchannans. I do find that there are some things that are easier with a crimp than a wire nut -- for instance those old residential boxes with 3 or 4 18 guage grounds about 1.5" long. I can get a buchannan back there with a #14 better than a wire nut. Also, (box-fill aside) for existing boxes, a crimp takes up MUCH less room.

So are the green wire nuts UL approved for clearing a fault?

That brings up another question. When I have to terminate a 10 stranded to a box or HWH I always use a #10 fork Sta-Con. Is this listed to clear a fault?

In my area only ferrules aka crimp tubes or green wirenuts are approved for residential. They are not required for commercial. I buy them in bulk cheap.

Is that a local code requirement or something that a particular inspector likes to enforce?

Doh! Point taken.

When looking at the "bite spring"on a greenie (made that one up) they are identical to those of the reds..perhaps a different material in the plastic insulation?

I dont know whose code it is I learned about it about 20 yrs ago and it is enforced by evryone. The ferrules you can crush with your dykes or linemans with crimp attatchment green wirenuts are expensive but required if you want to pass inspection

Sounds like anarchy. Why bother buying a codebook if they make up their own rules?
