Is there a thread or code article that requires all wires in a cable to be terminated or landed , this is a service cable 4/0 4 wire for single phase meter and panel. THANKS GEO
 
THANKS BOB
My issue is that the extras are cut off to short, which is no longer a spare.
Three phase panel , single phase meter socket , things just do not match. Do not want to make it personal as what I expect. THANKS FOR YOUR HELP!
 
What you're saying is different from the original question. There are codes that deal with the length of a wire.

Really? You can always splice onto a short conductor if you have a bit of gutter space. You can also abandon in place, and nip them short so they aren't used.

Parallel's 310.4(1) and length of free conductors 300.14 But, I dont think these pertain to your situation.

I was going on 300.14
"Length of Free Conductors at Outlets, Junctions, and Switch Points. At least 150mm (6in) of free conductor, measured from the point in the box where it emerges from the raceway or cable sheath, shall be left at each outlet, junction and switch point for splices or the connection of luminares or devices. Where the opening to an outlet, junction or switch point is less than 200mm (8in) in any dimension, each conduction shall be long enough to extend at least 75mm (3in) outside the opening."

Ethically speaking, don't you still have to "safe-off" the ends ?

I am lost in this thread, I can certainly run a 12/4 use only black and white then flush cut both red and blue at both ends, no requirement to leave them long or cap the ends.

Don't get lost. We need your input on this.

I suppose that's Ok as long as the ends have no possible means of coming into contact with a live buss.
 
I don't believe "Free Conductors" is refering to unused wires. It is refering to all conductors leaving the conduit or sheath. You can cut unused wires back flush but I would just tuck it in the back for future use.

I don't really even see that requirement. You could just as easily dress them back out of the way and not cap off the end by any means, and still be in compliance. The code is mostly mute on unused conductors.

110.14(B) Splices.

..."All splices and joints and the free ends of conductors shall be covered with an insulation equivalent to that of the conductors or with an insulating device identified for the purpose."
 
not trying to be a smarty, but does the term "conductor" also indicate "unused conductor" ? To be more specific, if a wire is pulled into a raceway as a "spare conductor", but is not being used as a "conductor", then is it a "conductor" or is it something else ?

on the other hand, I just happened to read the answer (I believe)
300.14 - Exception - unspliced conductors don't have to comply with 300.14

so I guess Bob's answer is correct ?

Pierre conductors that are cut off are not 'spliced' so 110.14(B) does not apply in the least.

But if they are left as "spares" I think 110.14(B) would.

That said, I don't think there is any prohibition with cutting off an unused conductor on both ends.
 
110.14(B) does apply. They have tucked the requirement for free end of conductors within the subsection on splices. Read the wording carefully.
This is one of the older parts of the NEC where it may not fit the way the new style manual requirements are now required.

I did read it.

110.14(B) applies to splices, it does not apply to conductors flush cut off and abandon in place.....or do you require all abandon in place conductors and cables to be insulated?

Ok then how much conductor do you have to have after the splices and connections are made?
