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
