Hello.

What do you guys use for drag lines and pulling in pvc conduit for hand pulling?

I've used measuring tape, pulling tape, twine, rope etc.. which all seam to cut into the pvc at elbows especially.

The only things I've found which don't is #12 or 10 thhn, or a snake.

Thoughts?

Thank you

Hint: Steel RMC elbows/90s. Ya don't gotta bond them if they are in the ground. 18" deep IIRC.

Thank you all

That's interesting.

The trench will be 18".

Is that 18" to the top of the 90 deep or a 90 in a 18" trench deep?




Mule tape.... I googled, and I vaguely think I have seen it in the past. Doesn't cut into the pvc??

They are supposed to be below grade 18". Inspectors here will cut some slack but they have to have some dirt over them.

Just pulled 200' today with mule tape in and pvc 90's. Not a cut or a scuff to be found.

Preferred over thhn/thwn ???

Don't think I've ever pulled anything other than that. Except a small length of I believe it was xhhw an engineered wanted to see.

On a similar note: Remember, when you're burying 18" that refers to the TOP of your conduit so your trench really needs to be deeper than 18" to avoid a problem with a tape measure wielding inspector.:)

Thank you.


The trencher gentleman asked if I would be back filling with sand or putting in caution tape.

NOT code required right?

He said the electrician for his last trench for a service had to do it. I can only think the inspector wanted the caution tape because it was service entrance (no protection) and maybe the sand because the earth was rocky ??

A warning ribbon (caution tape) is required for underground service conductors which are not encased in concrete- 300.5(D)(3).

Protection from backfill containing large rocks etc. is also required- 300.5(F). Sand is but one method permitted.
 
We had to do the same for the same and I learned the hardway about using pvc 90 s. The wire cut into one I got to dig it up. We used lots of lube on the rest and I learned rmc isnt just for stub ups

Just to clarify, this is stating minimum cover of 18" to ANY part of the elbow, not every part or the entire elbow. correct?

Around here, at least on the jobs I've been on, we put in the pipes, they backfill a bit, then cover it with sand, then we put the tape. Thought it was something standard. Made sense to me. Someone happens to hit sand, they know something is up.

I read that as if any part of the elbow is shallower than 18", it fails.
Otherwise, with a large enough bend you could have more than half the elbow entirely above the ground in your interpretation.
