About Electrical Systems Visual Lab
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
