Hello All,

What is the technique for getting 3/0 copper cable through 2 inch conduit? I have to run 3 total 3/0 wires along with a #4 bare copper wire for ground. I am running the wire through 2 sweep outs and about 25 feet of straight conduit. Should I run all the wires at the same time? Is there some tool to help pull the wires?

Thanks,

Zack

Technique? Brute force is more like it.

Pull all wires in at the same time, use a rope. As for tools, one or two of your buddies should be able to pull this in.

Skin off about a foot of insulation, trim off all but 2 or 3 strands of each cable, insert 1/2 way through the eye of the pulling rope, bend tthe ends over so that the bare copper does not run up on the insulated part of the conductors (makes the head too big), wrap some tape around the bare part to keep the ends from opening up during the pull (run the tape up onto the insulated portion. One man or 2 on the pulling end, one on the feed end guiding the wires in and pushing (1 push can be worth 3 pulls).

To add to what Tom said: use plenty of wire pull lubricant, the yellow "baby poop" type works best.

Also you want to use an ELECTRICAL pulling lub (available at the home horror stores) on the wires at the feed end.

Thanks, with a little swearing, some lube and a pulling rope I got the wires through. Thanks again for your help.
