In the world of industrial electricity and automation, the "Tablero Eléctrico" (Electrical Panel) is the brain of any operation. Designing one that is safe, efficient, and code-compliant used to be a manual, error-prone task. Today, CAD (Computer-Aided Design) software has revolutionized the process.
This article explains what "Tablero Eléctrico CAD" means, why you need specialized software, and how to create professional panel layouts.
Many CAD packages (like SEE Electrical) offer simulation. Press "Play" to virtually toggle switches and see if the logic works. This catches ladder logic errors before a single wire is cut.
Organization is key to a readable CAD file.
| Layer Name | Description |
| :--- | :--- |
| E-BORDER | Title block and sheet frame. |
| E-COMP-POWER | Power components (Breakers, Fuses). |
| E-COMP-CTRL | Control components (Relays, PLCs). |
| E-WIRE-POWER | Power wiring (Thick lines). |
| E-WIRE-CTRL | Control wiring (Thin lines). |
| E-TERM | Terminal blocks. |
| E-DIM | Dimensions for drilling and spacing. |
Ideal for mechatronics. It integrates 3D panel layout (wire routing) with 2D schematics.
