Electrician Apprentice Hours
OJT Hour Track, NEC Calculator
Free · Designed for iPad. Not verified for macOS.
Log today's OJT hours in seconds, then run voltage drop, conduit fill and box fill on the spot. Free, no ads, no subscription — built for US electrician apprentices
Every hour you work counts toward your license — if you can prove it.
Electrician Apprentice Hours is a jobsite hour log and NEC calculator built for US electrician apprentices working toward journeyman. Log the day in seconds, keep a record your licensing board can actually read, and run the everyday calculations without leaving the app.
Completely free. No subscription, no in-app purchases, no ads.
LOG YOUR OJT HOURS IN SECONDS
• Tap the hours, pick a category, save — a full day takes about five seconds
• Enter total hours or start–end times
• Tag every entry with employer, work category and an optional note
• Logging and calculators work fully offline, anywhere on the jobsite
SEE HOW CLOSE YOU ARE
• Live progress toward your hour goal — 8,000 by default, or set your own
• Hours remaining and hours logged this week, at a glance
• Totals broken out by work category and by employer
A RECORD YOUR BOARD CAN READ
• The 8 standard OJT work categories — rename, recolor, reorder or add your own
• Store each employer with supervisor name and license number
• Export a certification-ready PDF or CSV
• Combined records split hours by employer, so each supervisor certifies only the work they actually supervised
7 NEC CALCULATORS FOR THE FIELD
• Wire size / ampacity — AWG by load and temperature
• Voltage drop — volts and % over distance
• Max circuit distance — longest run within a drop limit
• Load calculator — service size by NEC Article 220
• Motor calculator — circuit sizing by NEC Article 430
• Conduit fill — NEC Chapter 9 fill percentage
• Box fill — conductors per box
Every result shows the inputs it used and the code articles behind it, so you can check the work instead of trusting a black box.
TALK INSTEAD OF TYPING
Say "240 volts, 6 gauge wire, 30 amps, 100 foot run" and the calculator fills itself in. Useful when you're gloved up on a ladder and typing isn't happening.
BUILT AROUND YOUR APPRENTICESHIP
• Set your program or local, your state and your apprentice level
• Daily reminder so you never lose a day you already worked
• Light and dark mode
• Optional sign-in to back up and restore your hours across devices
