I got a whole bucket of string and a vacuum. Crap, I guess the limit would be the spool of wire.
your sucking thru emt ? Get out the duct tape

The only limit is how long your fishtape or rope is.
Yet another 'urban code' rears it's ugly head again.
Doesn't anyone use a vacuum to suck lines in anymore?
You can vac or push 10,000 feet of string in, but I doubt you'll pull much more than a couple 12s back with it. 10,000 feet of jetline doesn't help of your rope is only 1,000 feet.
Haven't you ever spliced two ropes together by untwisting and braiding them back together it works very well and never had any problems. I would suggest if the run is real long make sure that the rope is in good shape so that it want break.
If it's that long of a run, I'd just buy a longer rope and charge it to the job.
I am in a "discussion" with my boss about how often you have to put a j box in a run of emt. I know that every 360 degrees you have to have a j box. He is telling me every 100'. I have always installed j boxes every 100' for the ease of pulling but I don't recall a code on it. I'm a little rusty on the code but almost 100% positive on my call.
That is addressed in 250.4(A)(5), one of the very few performance type rules in the NEC...most of the NEC is prescriptive.What about fault current issues after a certain distance?? not addressed in the NEC?? I remember reading part of a study that looked into it. I'll try to find it ..
And pizza and cold coke for the boys
I am not aware of any rope with that type of construction that is permitted to be used with a tugger. Most rope of that type is too dynamic (stretches too much under load) to be safely used with a tugger.Haven't you ever spliced two ropes together by untwisting and braiding them back together it works very well and never had any problems. I would suggest if the run is real long make sure that the rope is in good shape so that it want break.
