Electrical & Electrician App vs Electrical Systems Visual Lab

Learn electrical work the way you wire it. Electrician App by VoltageLab is an electrical training app for electricians, apprentices and students. Study wiring, grounding, motors, load calculations and electrical theory with study plans, quizzes, guides, videos and a circuit simulator, all matched to the electrical standard you work under. STUDY PLANS Type a topic such as grounding and bonding, conduit fill or motor protection, and get a day-by-day plan. Each day has short lessons and a quick check at the end, so you always know what to study next. QUIZZES THAT EXPLAIN THE ANSWER Practice questions on any electrical topic, from Ohm's law to branch circuits. Every answer comes with a clear explanation and the code section it is based on, so you learn why, not just what. ELECTRICAL GUIDES AND DIAGRAMS Illustrated guides on wiring and installation, protection and grounding, control and switching, motors and transformers. Read a guide, then quiz yourself on it. Save guides to read offline on the job. ELECTRICAL WIRING SIMULATOR Build circuits level by level. Place the battery, resistor and lamp, close the switch and watch voltage, current and resistance change. A safe way to understand electricity before you touch a live panel. VIDEO LESSONS WITH QUIZZES Watch electrical video lessons on motors, power systems and electrical machines. Short questions appear while you watch, so the key ideas stick. STUDY YOUR CODE SECTION BY SECTION Browse your electrical code by area: definitions, branch circuits, feeders, load calculations, services, overcurrent protection, grounding and bonding and more. Each area is broken into quiz topics with their code references. FLASHCARDS Create a flashcard deck on any topic in seconds: voltage drop, ampacity, conductor sizing, electrical formulas. You can also build flashcards from your own notes, a PDF, a photo or a YouTube link. TIMED PRACTICE TESTS When you want a full run, take a timed practice test with multiple-choice and written questions, graded with worked answers. Useful for electrical licensing exam practice and for checking what you know. YOUR STANDARD, YOUR CODE Pick the standard you work under: NEC, CEC, BS 7671, AS/NZS 3000 or IEC 60364. Quizzes, plans and answers follow your choice. TOPICS COVERED Electrical wiring and wiring diagrams, residential and commercial wiring, grounding and bonding, branch circuits and feeders, GFCI and AFCI protection, overcurrent protection, conduit fill, box fill, voltage drop, ampacity and conductor sizing, load calculations, services, motors and motor controls, transformers, three-phase power, Ohm's law and electrical formulas, AC and DC circuits, troubleshooting, solar PV and EV charging. BUILT FOR Electricians who want a quick daily refresher, electrical apprentices working through their training, candidates practicing for a licensing exam, electrical and engineering students, maintenance technicians, and anyone learning how electricity works. Free to download. Some features need a Pro subscription. Terms of Use: https://www.voltagelab.com/terms-of-use-electricpal/ Privacy Policy: https://www.voltagelab.com/electricpal-privacy-policy/

Master electrical systems the visual way — with three new engineering tools, eight animated simulations, 76 illustrated diagrams, NEC code reference, and structured curriculum. Built for electricians, apprentices, and electrical engineers. NEW IN VERSION 2.0 — ENGINEERING TOOLS TAB Three practical, field-ready tools exclusive to this app: Conduit Fill Calculator — Select conduit type (EMT, IMC, RMC, PVC Sch 40/80) and trade size, add conductors by AWG, and get live NEC Chapter 9 fill compliance — green for pass, red for violation. Wire areas pulled directly from NEC Table 5. NEC Electrical Inspection Checklist — 52 NEC code items across six inspection categories: Service Entrance & Metering, Panelboard & Overcurrent Devices, Branch Circuits & Outlets, GFCI & AFCI Protection, Grounding & Bonding (Article 250), and Special Systems. Tap to check items, track your pass rate, and reset for the next job. Wire Ampacity Guide — Interactive NEC 310.16 reference for copper and aluminum conductors from 14 AWG through 500 kcmil. Apply ambient temperature correction and conduit fill derating — adjusted ampacity updates instantly. Tap any row to highlight it for quick comparison. EIGHT ANIMATED LAB SIMULATIONS Watch electricity behave in real time through canvas-rendered interactive simulations: Power Grid, 3-Phase Phasors, Voltage Drop, Ground Fault/GFCI, Transformer, Motor Control (DOL + VFD), Arc Flash, and Panel Load Calculator. 76 ILLUSTRATED DIAGRAMS Professional electrical diagrams across 10 categories — Fundamentals, Power Systems, Service Entrance, Distribution, Branch Circuits, Conductors, Grounding, Motors, Floor Plans, and Special Systems.
