    Sizing conduit for Compact AL conductors

    I have read through my previous post and there seems to be no clear chart etc. what conduit sizes to use for these conductors. Thanks.

    You need to calculate the size as you do any other wire using Tables 4 and 5 in the back of the book- Chapter 9

    Go here:

    http://www.cable.alcan.com/CABLEPUBLIC/en-US/

    Then click Information Center/Price Sheets, Cut Sheets, Brochures/Product Cut Sheets
    then select Stabiloy-XHHW-2 and print that pdf. All wire dimensions, ampacity conversion, etc are there.

    Really, when you get right down to it, the sizing charts are not really OK for most feeders, since most feeders in conduit include different size conductors. With computers and smart phones nowadays, there a multitude of apps that can assist you in this.

    I disagree. Except for the EG, most large feeders are the same size conductors. Most neutrals are sized the same as phase conductors.

    Do these apps include size data for compact cable such as Stabiloy products?

    i'm looking for an app that can pull the feeders...... no luck yet.

    Why would you not use XHHW-2?

    The EGC was the conductor I was referring to. find me a chart in the NEC that includes 4-3/0 and a #6 in a 2" PVC conduit. You still need to size the conduit for the ground.
