Hide comments. You just locate the table for the raceway type you're using, find the conductor type on that table, and look up the size and quantity. Other times, you know how many conductors will go in a given run, and you need to make sure you install a big enough box. Hide comments. It's a matter of adding up individual volumes of assembled parts [ Where insulated conductors 4 AWG or larger are pulled through a metal wireway, the distance between raceway and cable entries enclosing the same conductor must not be less than required by What is the total number of conductors used for the box fill calculations in Fig. The distance from the raceway entry to the opposite wall must be at least six times the trade diameter of the largest raceway, plus the sum of the trade sizes of the remaining raceways on the same wall [ The high cost of wireways precludes using them for other than short distances, except in some commercial or industrial occupancies where the wiring is frequently revised. Either way, you calculate box volume and conductor volume.

    Each unbroken conductor that runs through a box, as well as each conductor that terminates in a box, is counted as a single conductor volume.

    You just locate the table for the raceway type you're using, find the conductor type on that table, and look up the size and quantity.

    You can omit equipment-grounding conductors and up to four 16 AWG and smaller fixture wires from box fill calculations, if they enter the box from a domed luminaire or similar canopy e.

    Each single gang device yoke regardless of the ampere rating of the device counts as two conductor volumes, based on the largest conductor that terminates on the device. In the manufacturing process, these conductors are compressed so much that the spaces between strands are nearly eliminated.

    In no case can this exceed the box volume [ Where multiple conductors of the same size are installed together in a raceway, you can determine the maximum number of conductors from the Annex C tables.

    The high cost of wireways precludes using them for other than short distances, except in some commercial or industrial occupancies where the wiring is frequently revised.

    Calculating box volume is a matter of adding up individual volumes of assembled parts [ Each unbroken conductor that runs through a box, as well as each conductor that terminates in a box, is counted as a single conductor volume. This covering increases the dimensions of the conductor more than the thin nylon cover on conductors such as THHN.

    Each single gang device yoke regardless of the ampere rating of the device counts as two conductor volumes, based on the largest conductor that terminates on the device.

    You calculate box volume per Where insulated conductors 4 AWG or larger are pulled through a metal wireway, the distance between raceway and cable entries enclosing the same conductor must not be less than required by Table Insulated equipment-grounding conductors for receptacles having insulated grounding terminals isolated ground receptacles [ If the cubic inch volume of the mud ring is not stamped on it or given in the problem, we cannot include it in the box volume.

    A metal wireway is a sheet metal raceway with hinged or removable covers for housing conductors [
