    Pulling Wire

    Is it quicker to pull wire through underground conduits rather than overhead? Setup still the same. Don't think it should make a difference as conduit install would.

    Definitely faster underground. You wouldn't be on ladders or lifts.

    How is the set-up the same? Are you picturing a very specific run and in this exact scenario there is no difference in setup and you are only concerned with whether the wires go down then up versus up then down?

    Minor things to consider MIGHT be that pulling can be easier in a metallic conduit instead of plastic. Some exposed conduit allows for "helping" the pull along the way (sometimes you get lucky and can help it through a fitting you know it is sticking on, etc.) Conversely, a conduit run that has some flex it in can make it harder to pull, and underground is usually pretty rigid. It's also probably airtight if you want to use a vacuum without taping the fittings.

    Also, feeding down into the first bend gives a lot less friction than when the rope pulls it up into the first bend.

    I don't know, most overhead pulls are indoor with no rain or snow or mud. Lubrication tends to work better if the conduit isn't full of water. You can see if conduit is damaged in any way.


    The only way I know if a pull will be easy is if I ran the conduit. If I'm going to be pulling the wire the pull will be easy.
    The 95% of people that you can't trust give the other 5% a bad name.

    Your labor units don't distinguish any difference

    Isn't the setup of the reels/pulling equipment the same whether your pulling through overhead conduit or conduit in a trench?

    Not for wire pulling. That's why I'm asking. Always been told there's a labor savings when installing conduit in a trench or on the floor as opposed to overhead which makes sense but never got info on wire pulls being different.

    They are far more likely dependent on other factors present than the differences between overhead and underground.

    pipes in a ditch need to be plumb an pretty where they enter and exit the slab.

    if you are pulling feeders, it's probably a little bit faster pulling into the ground.
    if you can set your spools up at the gear, the wire goes into the ground pretty
    effortlessly.

    the setups of spools tuggers and whatnot is where the labor is saved.

    a time honored tradition is that the electrician pulling the wire should be the
    one who ran the conduit. this way, if they were an idjit, it's a self inflicted wound
    trying to pull the wire.

    if you know what you are about, you can pull long feeders by yourself. it's not
    commonly done, but it's doable.

    longest i've ever pulled solo is 500 MCM aluminum simpull, underground, 700'.

    the trickiest deal is getting it started. i use maxxis tuggers to get the pulling head
    in the pipe, and then go to the other end, and use a targetcam to watch the pull
    while i'm pulling.

    off grid remote camera. 4 mile range. 6 hour battery life.
    can view up to six cameras at a time.

    the maxis triggers.... i won't pull wire without them.
