Labor is definitely a big part of pulling wire, especially long pulls. But, it depends on how you are going to pull it. Do you have a tugger or a wire feeder? Or is this going to be pulled by hand?
What size wire is it? How many J-boxes are in the run and does it go straight through the J-box or out the side? Does the point of origination need to be shut down? And what is the weather like? If its cold....good luck
I am in charge of the one-line at my jobsite right now and those are the questions I ask myself before we start to pull our wire. It is VERY important to make sure all the ducks are in a row before pulling wire.
And just like everything else, it make look smooth on paper, but anything could go wrong in the middle. We recently were pulling a parallel feeder, and the first one went fine (we were using a tugger and wire feeder), but the second one broke the head about 5' after it came out.
All in all, yes labor is a big part if you are going to pull it by hand. But if you have a tugger and feeder, all you really need is, maximum, 6 people.
Probably comes from the Bible, "going down to Egypt", wasn't a good thing. I saw a few pulls go south. One was in a cable tray, outdoors at a power plant. We were pulling quite a ways through a double 90 or an offset and the wire jumped right out. There was an outbuilding right there where it jumped about the size of a shed and it slammed right into it and damaged it a bit. Nobody got hurt so it was pretty funny. Another one was a hospital riser, forget which floor, pulling up from the basement. I guess the fingers let loose. "What goes up must come down!" Then of course there's the "when you don't have a tugger" substitute, ie: the pick up truck, the back hoe (did that once) etc. Any body else got a "Going south story?
