If one cannot figure how to make something work mechanically - as has been done for years and is an accepted trade practice - maybe one should look into a different line of work

It is not even hard.

Here is one I did with 12 AWG just a few minutes ago. I did it just like I always do it. It took very little time and I used just whats in the picture.

It is tight and it is a good connection. :smile:

It might be ok (Stranded under screw) but the screw seems loose to me. If it was tight the strands would be spilling out from under the screw. No offense, but when I see it done like that I think to myself "What a hack!" It only takes a second to crimp a sta-kon on (with the proper tool, not linemans pliers.) and tighten the screw to proper torque. Btw, what does the listing instructions say this? I dought it says use stranded for either screw or back-stab.

So now the options are:
a) put a fork terminal on the stranded at the CB
or
b) splice a solid tail on the stranded at the CB

...and then..
at the device:
a) put a fork terminal on to go under the screw
or
b) put a solid tail on to under the screw.

That seems like a lot of unnecessary work.
So the "simple solution" is to ban stranded :grin:
or learn to make the stranded connections like others have for years :roll:


I see it as "dumbing" down the trade. :mad:

It my opinion wrapping stranded is shoemaker, or if you prefer wood butcher. Ive been taught by a very good electrician not to do it. Sorry if I believe his ways over an internet expert. I have not seen your work maybe your a great electrician too, either way your opinion means very little to me. If you answer a question with a fact and I will respect you for that. I know Iwire has helped me alot of times on here with facts however sometimes i disagree with his opinion. Its nothing personal, I was simply interpreting realolmans post differently thatn you.

Hacks (imho)

I'm with you. I have pulled out too many receptacles to find standed wires that fall off the devices. Even if "tight" when installed, the connections can become loose over time.

Perhaps this thread would have been better served to make it a Vote to see what others do?

Where they really 'falling off' or did you just not like how it looked?

That applies to all connections, stranded, solid or fork terminal.

Who among us would change our work habits based on the poll results? :D

I will leave a tiny piece of insulation on the end of the standed wire when I wrap the wire around a screw terminal. The small piece of insulation will hold the strands together pretty good.

I use the same method. One JW showed me a method where he split the stranded, twisted the two sections then brought one side in on each side of the terminal and twisted the two sides together. Then he trimmed with a pair of diagonals. I never liked that method personally. Have used spade Stakons if available or spec'd.

A wood butcher is a carpenter...:roll:

For years sailors were taught that the world was flat...now I am no expert on sailing - and in fact have never sailed, but trust this "internet expert" when I tell you that you won't fall off the edge of the earth and be eaten by a sea monster.

Here is a fact ~ it is allowed....check some of the links/posts to UL [ #20 ] and MFG that are posted.
As of now, the jury is out on the CR variety...with the BR series there is no question that side wiring w/stranded is approved by the MFG.

Maybe we need an NEC/UL/MFG thread akin to "Ripley's Believe it or Not!"

The information has been presented....if you want to stick your head in the sand, my advice is to put some sunscreen on your posterior ~ nothing personal, just my opinion.
 
Wow...this thread is still going and I thought I had a tough afternoon.

I will help it along a little more. :wink:

It has already been stated that UL permits, under a Standard for stranded conductors, for stranded to be installed directly to screw type terminals. If you are a doubter, spend some time in the White Book.

It is, as Bob has explained, not too difficult to make the termination.

Some say they have pulled devices out of boxes with the stranded conductor causing havoc...I would say the same can and does happen for just about any wiring method. It is not a fault of the wiring method, just the installer.

AND......if one does not like the method, then just don't do it.


Lets talk about something more important, say...what orientation for the ground prong on receptacles.:grin:

IMO... this is better.
And I didn't even use a pliers... I skun it with my teeth.
An spit the insulation on the floor.

In the Electrician's Bible, years ago, the recommended way to place stranded wire under a binding screw is as follows-

Strip wire to allow spinning the wire strands reverse to there natural lay.

Twist wire in reverse of the lay.

Use needle nose to make a 270 degree clock wise loop in the wire. Stick wire under screw and tighten.

The wire strands should pull in to make a neat and journeyman like job.

This was last read back in apprenticeship days (84-88), but still works if you don't have a sta-kon available.

True then, still true today. :)

Based on the posts I've seen I wouldn't change my work habits. I will add a little white tape, if need be.

One more time...GO STEELERS...GO STEELERS:grin:
