Electrician Field Kit is the 5-in-1 toolkit for electricians tired of buying three apps, Googling code tables, and handwriting test records. Bend, calc, document, reference, and export — one toolkit, one price. Most bending apps give you a multiplier off someone else's chart. This one uses real take-up and shoe-radius data from actual bender manuals — Greenlee, Klein, Ideal, Gardner Bender, Ridgid — so your marks come out right the first time. —— CONDUIT BENDING —— Any size, any angle, exact marks — fractions or decimals • Every trade size and type — EMT, IMC, Rigid — no "3/4 only" lock-in • Real take-up and shoe radius per bender, from manufacturer spec sheets — not a rounded multiplier from a 30-year-old pocket guide • Marks in fractions (1/16" or 1/32") to match your tape, or decimal • 8 bend types: 90°, offset, rolling offset, back-to-back, kick, 3- and 4-bend saddle, plus segment • Built-in digital level — check your bend angle right on the phone • Visual geometry diagram with mark-by-mark distances and a shareable spec card • Saved benders: Greenlee, Klein, Gardner Bender, Ideal, Ridgid, plus custom —— NEC CALCULATORS —— Eight calculators, backed by code — every result shows its chapter reference • Voltage Drop, single & three phase • Wire Size — ampacity-driven with temperature & fill corrections • Conduit Fill (Chapter 9) with visual packing preview • Box Fill (314.16), Motor FLA (430.250), Ohm's Law • EGC Sizing (250.122), including upsize for voltage-drop-corrected conductors • Ampacity Derating (310.15) — temperature × conductor-count with Pass / Fail • Switch NEC 2020 & 2023 in one tap — the numbers actually change —— PANEL SCHEDULES & FIELD TEST RECORDS —— You won't find this in any other bending or NEC app. Build, document, and export on-site. • Full circuit directory — number, load, breaker, wire, poles, phase, AFCI / GFCI — table or card view • Field tests: insulation, continuity, loop impedance, polarity, RCD / GFCI — instant Pass / Fail / Review • Both roll straight into one branded PDF report —— JOBS, PHOTOS & PDF (PRO) —— Save calculations, photos, and panel/test records under each job. Annotate photos with text and arrows. Export a clean, branded PDF for the customer or inspector — with iCloud sync across iPhone and iPad. —— REFERENCE, OFFLINE —— NEC tables (310.16, 310.15, Chapter 9, 250.122, 314.16, 430.250), U.S. wire color code, NEMA configurations, and a formula cheat sheet. —— PRICING —— Lifetime — $24.99 (one-time · recommended) Everything — bending, all 8 calculators, panels, tests, unlimited jobs, branded PDFs, iCloud sync, and every future update.
