PullCalc vs Derated

Greenlee continues to drive efficiency with PullCalc, an app that helps electricians and contractors approximate the pull force needed to install an electrical cable inside of conduit. Data is entered by "legs" and each leg is considered to be a straight run of conduit followed by a bend, except the last leg, which usually has no bend. The calculation for each leg requires the following information to be entered: - Wire size - Number of wires - Conduit I.D. - Duct Material - Material of the Cable Insulation - Coefficent of Friction* - Length of Leg - Bend angle - Vertical Rise *Due to unknown factors involved, it prohibits giving exact results, most notably the coefficient of friction. Lubrication, surface texture, and lay of the cable are never uniform along the length of a conduit run. Comparing the known forces of pulls against the estimated force should give you a guide as for a good coefficient of friction to use for similar future pulls, and a table with some suggested starting points for the coefficient of friction of well-lubricated cable is a drop down option in the app. If lubricant is not used, triple the values in the table.

Experience the simplicity of Derated, a cutting-edge conduit fill calculator designed with electricians in mind. This intuitive app goes beyond the basics, allowing you to effortlessly calculate conduit fill while simultaneously derating wires' ampacity. All in real-time. Adhering to the guidelines of the National Electric Code® (NEC), Derated simplifies complex calculations, providing accurate results without the hassle of load screens. Choose from various raceways and insulations outlined in the NEC, with dimensions and conduit/tubing area references from Chapter 9, Table 4. Insulated conductor dimensions are sourced from Chapter 9, Table 5. Setting up calculations is as easy as QuickBend, ensuring a straightforward process for adding sets of wires. The results are not only accurate but also easily shareable. Whether you're collaborating with colleagues or explaining a wire pull to a client, Derated streamlines communication by sharing results effortlessly.
