// ABOUT
Master electrical systems the visual way — with animated simulations, 76 illustrated diagrams, NEC code reference, and hands-on lab calculators. Built for electricians, apprentices, students, and engineers. ANIMATED LAB SIMULATIONS See electricity come alive through eight interactive, canvas-rendered simulations: Power Grid — Watch electricity flow from generator → step-up transformer → 345 kV transmission towers → substation → distribution lines → homes. Adjust load and see the system respond in real time. 3-Phase Phasors — Rotating phasor diagram with live sine waves for L1, L2, L3. Toggle Wye/Delta, adjust frequency and voltage, and see phase vs. line voltage relationships. Voltage Drop — Animated particles slow as voltage is lost over wire length and resistance. See NEC 3% and 5% limits live. Adjust AWG, length, and current. Ground Fault / GFCI — Trigger a fault to watch fault current flow through the EGC, then see the GFCI trip when imbalance exceeds 5 mA. Transformer — Drag sliders to explore primary/secondary voltage, turns ratio, kVA, and efficiency. Motor Control — Direct-on-Line (DOL) starter with animated contactors and overload relay. Switch to VFD mode. Arc Flash — Available fault current and arc flash incident energy calculator with protection boundary visualization. Panel Load — Real-time NEC panel load calculation with demand factors and service size recommendations. 76 ILLUSTRATED DIAGRAMS Browse a curated library of professional electrical illustrations organized across 10 sequential categories — from fundamentals to special systems: Electrical Fundamentals → Power System & Utility Service → Service Entrance → Distribution Systems → Branch Circuits → Conductors & Wiring Methods → Grounding & Bonding → Motors & Controls → Electrical Plans & Drawings → Special Systems & Renewable Energy Pinch to zoom on any illustration. Swipe to advance through each category like a slideshow. NEC CODE REFERENCE Instant access to the formulas, tables, and code sections you need most — organized into seven tabs: Formulas, NEC Codes, Wire & Conduit, Equipment, Controls & PLC, Standards, and Glossary. No internet required. STRUCTURED CURRICULUM Step-by-step lessons across Beginner, Intermediate, and Advanced modules, each with explanations, code examples, and quiz questions to reinforce learning. HANDS-ON PROJECTS Guided project walkthroughs covering residential, commercial, and industrial electrical work — with step-by-step instructions and design notes. WHO IT'S FOR Electrical apprentices • Journeymen & master electricians • Engineering students • Electrical inspectors • Contractors • Anyone studying for their electrical licensing exam Electrical Systems Lab — the visual reference you'll return to on every job.
