John T NEC code ?

When I install a wire nut Scotch lock or what ever you call it am I supposed to twist the wires first. I have seen it done twisting and not twisting, What does the Code say??? To make tool related I use my wire strippers first.
 
I cant tell you what the code says or doesnt say, I doubt it tells you but I can tell you how I was taught and how we instructed our electricians (but they did it as they pleased anyway lol)

Hold the stripped ends together close and in paralell (NOT pre twisted) and twist the nut till she bottoms out and stops turning then give it a few more twists so the insulated covered portions turn a couple times around each other which gives the twisted pair more strength versus the nut alone having to do all the holding.

As I recall (long time no warranty) thats the way the wire nut manufacturers recommend although Ive seen it done both ways and sure either will work BUT UN TWISTED WAS OUR METHOD.

This may be like asking which brand of oil or sparks plugs are best, with different methods and opinions so I gave ya mine......

PS this was for single solid wire, if its stranded I usually pre twisted,,,,,,,if one wire is stranded the other solid, I had the stranded one a bit longer then the solid one

I don't twist them with a plier. I just use the wire nut. My hands are still strong enough that I can twist them till even 4 or 5 12 ga wires twist together a couple of turns. Never been gigged for my wire nuts and passed a bunch of inspections.

The code does not cover that. The bag of wirenuts [if anyone ever reads it] says you don't have to twist . Lead stranded wires slightly. Best practice is to pull each wire in your splice to ensure it is not able to pull out of the group.This was covered in a discussion several weeks back. I have seen a twisted set of wires where ,when the wirenut was removed one did not make contact with the rest of the group [ a row of lights went out]. Looking at it it was with the rest twisted but somehow not touching any other. That was one in a million . Maybe that previous discussion was about adding tape to the wire nut. No tape.
It only takes a second to twist the group but works either way. Inspectors do not remove wirenuts and critisize things like that.
 
Nooooooooo don't tell guys to keep twisting once they reach the insulation. Now the box looks like doody when the next guy has to add more wires to the same splice.Only the copper should twist. MDAO.[my dumb a opinion]
 
Ol John T has it correct. No pre-twisting and no tape. Just use the proper size and number or properly stripped wires inside the proper sized wire nut.
 
Although just to add a good seating of the wirenut will add a turn maybe two to the insulated part of the wire but twisting all the way down the splice is bad and evil.
 
for my wiring on my home. I twist em, sweat solder with rosin core solder and then nut em.

Not taking any chances.

I also use good receptacles. NO pushing wires in little holes for me.
 
My code says;
Strongly twist the stripped copper ends together with lineman's pliers.
Cut a clean end with the side cutter of the lineman's pliers.
Twist on the wire nut type that has metal inserts inside.
Do each step like a man and not a sissie.
You want "tight" copper to copper for low resistance connections, especially for high current 240v circuits.

Sorry if I mis spoke, I intended to say just give her an extra turn or two (once seated down) but notttttttttt a bunch more lol

AS I predicted this is like asking for opinions on which brand of oil is best or which spark plugs are best lol PLENTY OF OPINIONS ON ANY THESE TYPE OF WIDE OPEN QUESTIONS

I just went on line and there are a gazillion videos of HOW TO DO IT and heres one in line with how I was taught but there are, of course, plenty of different opinions on this one

We report, you decide, its your money and your house so do as you please. That being said, hey if you want to solder then wire nut then tape I see no harm in that !!!!!!!!! But that wasnt your question.

FUNNNNNNN chat yall

John , It was more of a case of me not reading right . lol. I watched the Ideal movie that was posted and it is about right .The insulation does turn a turn or two. If the company wants them twisted first I twist first. I worked for a refridgeration guy that would watch you to see if you were twisting the wires with pliers first. He was a worrier and chewed his nails down to nothing. He would ask if you were putting the orange to purple or whatever the wiring was. Id say I'm doing exactly what you gave me on the cardboard you wrote the splicing on. I always say give 'em what they want and for engineers and architects give'em what they drew. My only redeeming quality is I don't take it upon myself to change things to " my way".
 
Thats kinda like I used to tell my kids when I mis spoke......I said DO AS I MEANT NOT WHAT I SAID LOL
