bare wire pulled thru conduit

[SparkyRules]

TIA, I cannot find any prohibition in the NEC from pulling bare wire ( grounding conductor of course) thru a race way? Anyone NEC art?

No problem.

NEC Art. 250.118 lists the types of EGC's and the physical characteristics. I see nothing in the NEC that prohibits a bare EGC to be installed in a conduit. However, I have been on some jobs where it is in the specs that the EGC be green/ green with yellow stripes. Not a NEC requirement but a job requirement.

I have worked on projects where the EGC for medium voltage circuits installed in a non-metallic raceway was specified to be a bare conductor.

If you are in a wet environment, then you have to consider galvanic corrosion between the bare conductor and the raceway.

Would 310.106 not prohibit solid wire sizes greater than #8 in a raceway (except where specifically permitted)

Sure, but a larger EGC could be a bare, stranded conductor.

I believe it's #8 and larger. Although there are some exceptions that allow a #8 solid in a conduit.

I will be pulling 3- 1/0 aluminum xhhw and 1 no.2 aluminum xhhw 220 feet. Conduit is installed I have 2- 90 degree long sweep 36-inch elbows and a site bent 60-degree elbow to pull thru from the lb to the new sub-panel. The rest of the run is pretty straight I do have a curve but was able to sweep thru it with the 10 ft sticks of conduit without using fittings. The pull is downhill somewhat if that makes a difference.

I will be pulling from the male end of the conduit into the female bell end I also beveled the inside edge of the male end. I have 5 quarts of wire lube two helpers to pull, me to feed and lube, and a helper to assist with feeding and lubing. I plan to run rags thru to clean the conduit then run a rag with lube before starting the pull.

My concerns are how to make a good solid wire pulling head and whether should I use pull rope or mule tape. I am concerned about cutting thru the last 90 using a rope but it might not be a problem. If I use pull rope 1/4 inch or larger? The last thing I want is to be 200 feet in and something pulls loose or breaks and I have to pull 200 feet of lubed wire out.

Am I missing anything that is going to cause heartburn doing this

Get a tripod and pulley, will make life easier if by the sounds of things you'd be pulling "up" at either end of pull. Better yet get a power puller.
AFA pulling head, the cable chinese finger grip type works well so long as you establish a tight grip to start. Another thing that can help is have enought wire so you can offset the individual conductors on the pulling end, it will allow the wire to negotiate the elbows easier.

Just curious. Why are you using number 2 aluminum as your ground wire? Wouldn't it be cheaper to use number three copper?
