Going to pull four #6 wires through a 1.25" PVC conduit tomorrow. 60' total, including 2 sweeps. I have cable lube.
Will a single 200-pound pull-string work, should I double up, or get something larger? |
I don't have a fish tape. 
I'd be tempted to buy one, but the excavation has gone an extra day, and blown a lot more money than was planned. They ran into issues with the retaining wall, have to repair it, and are doing extra work to get the structure as far into a hillside as they can, but it means a lot more digging and bringing in more soil. Ah, well. Such is life. The good-ish news is that with the new placement, the run will only be about 30-35 feet. The bad news is that I already bought the wire.

I used a 1/4" braided nylon rope that I put through the PVC conduit as I assembled it. With lube it was effortless to pull 70' with two 90* sweeps. My wire was three pieces of 1/0 copper, plus a bare ground, through (IIRC) 2 1/2" conduit. 
Edit: The main thing is to lay them all out nice and straight, then use periodic black tape to make a nice bundle, then have someone feeding as you pull. Easy! 
Edit II: One more thing--leave one wire longer for your pull loop and attach the rope to it, then tape the crap out of where it lays along your bundle. |
