    Existing Duct Banks

    Have hundred of feet of existing 4" PVC duct banks we have to pull through. They were installed in the past 2 years. We have to attach to the existing conduits and extend them about 50' to equipment locations. We will obviously mandrel the conduits.

    Any problems or things things to be aware of in this situation since we did not install the conduits? Guess it doesn't really matter. Thanks.

    First thought.

    Do the existing conduits have RMC elbows/90s? Might make a difference when repulling conductors....

    No they don't. No 90's just horizontal 45's and offsets.
