## What is Electrician Field Kit?

Every NEC calculation, every conduit bend, every panel schedule and field test — from one app, on the job, fully offline.

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. Pay once. No subscription. No auto-renewal.

Pro Annual — $14.99/year (7-day free trial). Everything included, cancel anytime.
Pro Monthly — $3.99/month.

Family Sharing supported. Restore anytime in Settings. Subscriptions auto-renew unless canceled at least 24 hours before the period ends. No ads, no tracking, no account.

—— BUILT FOR THE FIELD ——

One-handed with gloves. Dark mode by default, high-contrast bright mode for direct sun. Every result carries its NEC reference — because the right answer needs the receipt.

—— DISCLAIMER ——

A calculation and reference tool based on publicly available NEC standards. Not a substitute for professional engineering judgment or inspection by an authority having jurisdiction. Always verify against the NEC edition adopted in your jurisdiction and manufacturer specifications.
