Electrical & Electrician App vs Electrical Systems Visual Lab

Everything for electrical work, in one app. Electrician App by VoltageLab is an all-in-one electrical training app for electricians, apprentices and students: wiring lessons, quizzes that explain every answer, an AI tutor, study plans, a circuit simulator, guides and flashcards, plus NEC exam prep when you need it. All of it follows the code you work under. WIRING LESSONS Step-by-step lessons on residential wiring: switches, receptacles, switched outlets, GFCI and AFCI protection, panels, grounding and bonding. Animated pictures label each part, and each lesson names the NEC rule behind it. QUIZZES THAT EXPLAIN THE ANSWER Practice questions on any electrical topic, from Ohm's law to conduit fill. Every answer comes with a clear explanation and the code section it is based on, so you learn why, not just what. AI TUTOR Stuck on box fill, voltage drop or a load calculation? The tutor works through it with you one step at a time and checks your answer, instead of handing you the result. NEC EXAM PREP, SECTION BY SECTION 1,425 practice questions across 8 NEC exam sections, from general requirements to theory, safety and trade knowledge. Work through one section at a time, see your score per section, and read the explanation and NEC reference behind every answer. Useful for licensing exam practice and for keeping your code knowledge sharp. STUDY PLANS Type a topic such as grounding and bonding or motor protection and get a day-by-day plan with short lessons and a quick check at the end of each day. ELECTRICAL WIRING SIMULATOR Build circuits level by level. Place the battery, resistor and lamp, close the switch and watch voltage, current and resistance change. ELECTRICAL GUIDES, FLASHCARDS AND PRACTICE TESTS Illustrated guides on wiring, protection, motors and transformers that you can save offline. Flashcard decks on any topic in seconds. Timed practice tests graded with worked answers. YOUR STANDARD, YOUR CODE Pick the standard you work under: NEC, CEC, BS 7671, AS/NZS 3000 or IEC 60364. Quizzes, lessons and answers follow your choice. TOPICS COVERED Electrical wiring and wiring diagrams, branch circuits and feeders, grounding and bonding, 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, solar PV and EV charging. BUILT FOR Electricians who want a quick daily refresher, apprentices working through their training, candidates practicing for a licensing exam, electrical and engineering students, 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. Full-screen slideshow with pinch-to-zoom. Optimized for iPad with side-panel layout. NEC CODE REFERENCE Formulas, NEC Codes, Wire & Conduit tables, Equipment specs, Controls & PLC, Standards, and Glossary — organized and searchable, no internet required. STRUCTURED CURRICULUM Step-by-step lessons across Beginner, Intermediate, and Advanced modules with explanations, code examples, and quiz questions. WHO IT'S FOR Electrical apprentices · Journeymen & master electricians · Electrical engineering students · Electrical inspectors · Contractors · Anyone studying for the journeyman or master electrician licensing exam
