Ok, 300' pull with about 14 #14s and 12s ( stranded) . Along the way several circuits will be dropping off. Do I pull all together and then tie off the ones that stop along the way and hope the wire does not twist OR do I pull the circuits that go all the way with a string to pull in the shorter circuits after OR is there another way??????

Pull your longest ones first with a pull string,go to the next box grab the string and pull in your next set,exc,exc,....
I would pull from your first junction box where you have a drop to the panel (starting point) with all the conductors... Then tape the rest in varying lengths together and pull the remainder, stopping to untape when needed....
Trying to tie off a group (2 or more wires) and hoping for the best is a receipe for a bad day, in my opinion...

Wouldn't it be easier to put a pull string to each place they will drop off and just pull them all at the same time to their destination point?
Sometimes I'll pull them all long and then pull them back one at a time. Or I just cut them off and scrap them.
Just keep in mind what they are paying you versus the cost of the wire. Sometimes it's cheaper to scrap than screw around with trying to save a few #12's.
If you decide to measure it off and tape sets to the side of your longest set, use plenty of tape and leave a flag. I can't remember how many times someone just throws a few wraps of tape around the next set of wires and they pull out of the tape in the middle of the pull. Then you notice a couple spools not turning and you're back to square one.
Every situation is different.

I use this method everytime.
SERIOUSLY, #12 is what .15-.20 cents/foot? If your labor costs for "saving" a given amount of wire exceeds the cost of that wire itself then is it really worth it trying to pull it back versus leaving it long and wasting the [extra] wire?Sometimes I'll pull them all long and then pull them back one at a time. Or I just cut them off and scrap them.

I'm still waiting on the derating question.

I'm a glutton for punishment. I shove the fishtape back in there and pull the next sets and the next sets and bla bla bla.....

A few questions about this 300' pull scenario. I would think that any aproach would involve oversized pipe. I wouldn't want to do any multiple pulls/pulling strings/slipping wires in a tight fill. Is that a correct assumption?
I have suggested the pull string idea to jw's in the past and I usually get shot down for the reason of burning through the wires insulation on 90's. Is this a legit concern?

Depending on the scenario I usually pull them all to a reasonable spot and pull back wires to there respective boxes. Most of the time having longer wires helps and you can push to the next box off the main run.
In any case lube the **** out of it so that pulling past/pulling back is a breeze.

I still think installing a pull string for each place you want it to go to the destination junction box where they all meet set up your spools in each area and pull all of them at once so they are all going at once making the pull easier.

yes it Is ! Poly line will burn through insulation quicker than you can blink , and no amount of soap will keep that from happening . Not to mention when you pull a bunch of wires with a string , what do you think happens to the string ? It doesn't lay nice and flat in the bottom of the conduit , that's for sure . " over pulling " is a last resort in my book . Either take the time to make a nice staggered head for all the drop offs , or pull to the farthest point or the mid point and pull back from there .butcher733 said:
Yes I have seen the pullstring burn into the wires. not just in 90s put if it wraps around the wires:no:
I have used the pull string trick, sometimes it works sometimes it doesn't. Even when it works, you can still burn through insulation. Running a fishtape back through works better and even better if you can get a nylon model to go. Depending on how much wire you want to save I recommend pulling everything to the end then pulling back to each box the wires you need, then all the way back to the spools and rewinding them. One at a time this works well, just takes some time and manpower.
