Read full description

Voltage Drop & Wire Size brings voltage-drop calculation and wire sizing into one practical workflow. Check a run with the conductor you already have in mind, see the result immediately, and move to a better size when the drop is outside your target. • Check voltage drop with the conductor you want to evaluate • Find the smallest available size that meets your selected target • Send the recommended size back into the calculation The app supports NEC / AWG and BS-style / Metric workflows across DC, single-phase AC, split-phase 120/240, and three-phase AC systems. You can enter load in amps or watts, choose copper or aluminum conductors, and work from preset drop limits or a custom target depending on the job you are checking. • Review voltage drop in volts and percent • See load voltage, running current, power loss, and a next-size-up comparison • Adjust power factor and installation method For NEC-based work, the app also supports ampacity-aware calculations with continuous load, ambient temperature, conductor grouping, and conductor temperature rating inputs. Saved calculations can be reopened later with notes, and ambient temperature can be shown in Celsius or Fahrenheit. • Review adjusted ampacity in NEC mode • Reopen saved calculations and keep notes with the job • Switch ambient temperature display between Celsius and Fahrenheit This app is intended as calculation guidance. Verify final conductor selection, ampacity, and installation requirements against the applicable standard and manufacturer data before use.
