ElectroSim — Electrical Circuit Simulator
Learn, practice, and design electrical installations without risking a single real wire. ElectroSim is a visual and interactive simulator designed for students, electrical technicians, and anyone who wants to understand how a circuit works before building it in real life.
🔌 Build your circuit by dragging and dropping components
Choose from a wide variety of real electrical components:
Breakers, circuit breakers, residual current devices, and fuses
Contactors, pushbuttons, and rotary switches
Busbars and terminal blocks
Phase, neutral, and ground sources
Single-phase and three-phase motors
Incandescent and LED lamps, indicator lights
Solar panels, batteries, and inverters
Voltmeters, ammeters, and multimeters
🧵 Wire with precision
Connect terminals by touching or dragging between components. The system automatically calculates the best wire routing, avoiding unnecessary crossings with other components or existing wires. Choose from 17 wire colors and 5 different AWG gauges (AWG 6 to AWG 14), just like in a real-world installation.
⚡ Real-time simulation
Press PLAY and watch power flow through your network: each wire displays its voltage and amperage depending on the connected source (solar panel, battery, or phase source). Detect short circuits, check your panel's logic, and correct errors before physical installation.
🎛️ Full canvas control
Free zoom and pan with multi-touch gestures
Grid with auto-snap for precise alignment
Dark and light modes
Show or hide terminals and labels as needed
Lock pieces to prevent accidentally moving your finished design
🔍 Designed for learning
Whether you're an electrical student, a trainee technician, or a curious hobbyist, ElectroSim lets you freely experiment with electrical panel configurations, understand current behavior, and gain confidence before working on real-world installations.
🔒 Privacy First
ElectroSim requires no account, no internet connection, and collects no personal data. All your work is saved locally on your own device.
Developed by Indudesk, a studio dedicated to creating technical simulators for electrical and fluid mechanics trades.
Assemble electrical panels, connect wires, and observe actual voltage and current.
