Box Fill Pro is an easy to use app that calculates "Box Fill" requirements for an electrical wiring box. - Detailed calculations, broken down by indivdual wire size and component. - Optional "Cable mode" sizes boxes by counting cables, to simplify common calculations - Volumes for standard boxes, and "typical" plaster rings for handy reference. - All inputs and results on a single screen. No "Navigating" to do a simple calculation. - Easy sharing or documenting of results via email. - Written by a working electrician to make fast and useful calculations. - Significant new features, which are a partial subset of "Electrical Wiring Pro Plus", the premier electrical wiring app from Intineo LLC.

About

PullCalc

This app assists electricians and contractors in estimating the pull force required for installing electrical cables in conduit. Users input details for each leg of the conduit run, including wire size, conduit ID, and bend angles, to generate an approximate pull force calculation.

Highlights
  • Estimate pull force for cable installation
  • Input data by conduit legs
  • Supports various input parameters (wire size, conduit ID, bends)
  • Includes coefficient of friction guidance
  • Provides suggested friction coefficients for lubricated cable

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.
