Electrician Field Kit: NEC

Conduit bends, voltage drop, NEC references — every calculation an electrician needs, right in your pocket. Built for the field, not the office.

Electrician Field Kit is the modern toolkit for licensed electricians, apprentices, and contractors. Stop juggling four apps to bend a piece of conduit, size a wire, look up a code, and write a report — do all of it in one place, organized by job, fully offline.

— What you get —

Conduit Bending • 90° back-to-back, kicked, and compound bends • Offsets and rolling offsets at any angle • 3-bend and 4-bend saddles with center-line geometry • Segment bends for large-radius runs • Visual bend diagram with mark-by-mark distances • Save your benders: Greenlee, Klein, Gardner Bender, Ideal, Ridgid, plus custom

NEC Code Calculations (NEC 2020 + 2023) • Voltage drop (single and three phase, copper or aluminum) • Wire size driven by ampacity, with temperature and conduit-fill corrections • Conduit fill from Chapter 9 with a visual packing preview • Box fill per 314.16(B), with device, clamp, and grounding rules • Motor full-load amperage from 430.250 • Ohm's law and three-phase power • Toggle between NEC 2020 and 2023 with one tap • Every result shows the chapter reference — tap to jump to the table

Quick Reference (Offline) • Common NEC tables: 310.16 ampacity, 310.15 corrections, Chapter 9 conduit, 250.122 EGC, 314.16 box fill, 430.250 motor FLA • U.S. wire color code and NEMA configurations • Formula cheat sheet for daily math

Jobs, Photos, and PDF Reports (Pro) • Save calculations and photos under each job • Annotate photos with arrows, circles, and notes • Export a clean, branded PDF report — perfect for your customer or inspector • iCloud sync across iPhone and iPad

— Built for the field —

Designed for one-handed use with gloves on, in dark mode by default, with high-contrast bright mode for direct sun. Tabular numbers don't jump. Errors stay inline, never as pop-ups. Voltage-drop, wire-size, and bending results all carry their NEC chapter sources, because the right answer also needs the receipt.

All results are produced from formulas and tables derived from publicly available NEC standards.
