Automatic Protection Selection

System selects MCBs (B10, B16, C16) and cable cross-sections based on circuit power. Compliance with electrical standards.

Visual Distribution Board Editor

Design distribution board layout on an interactive editor. Arrange modules on DIN rails and generate single-line diagrams.

3-Phase Distribution

Algorithm automatically distributes load across three phases (L1, L2, L3), ensuring symmetry and avoiding uneven loading.

What is electrical design?

Electrical design is the process of planning electrical installation in a building. It includes determining the number of circuits, selecting protections (circuit breakers), placing sockets and switches, and designing the distribution board. Proper design helps avoid overload problems and ensures safe operation.

Why design electrical before construction?

  • Avoid wall chasing after finishing - all points will be in the right places
  • Save on materials - precise list of cables and protections
  • Ensure safety - properly selected protections prevent fires
  • Electrician gets a ready project - faster and cheaper execution

What does electrical design software offer?

Electro Planner is a comprehensive tool for designing electrical installations that automates many time-consuming processes and ensures compliance with standards.

How to design electrical step by step?

1. Determine rooms and their functions

Start with a list of rooms: kitchen, living room, bedrooms, bathroom, garage. Each room has different electrical requirements - kitchen needs more circuits than bedroom.

2. Add electrical circuits

For each room, add circuits: general sockets (B16), lighting (B10), and dedicated circuits for appliances - induction hob, oven, dishwasher, washing machine need separate circuits.

3. Check automatic selection

System automatically selects: circuit breakers (B10, B16, C16), cable sizes (1.5mm², 2.5mm², 4mm²), RCDs, and phase assignment for 3-phase installations.

4. Download PDF documentation

Generate a complete project ready for the electrician. Report contains everything: circuit list, distribution board diagram, power balance, and material shopping list.

Common questions about electrical design

Find answers to the most important questions in the FAQ section. Learn how many circuits you need in the kitchen, when to choose B10 vs B16 breaker, and whether you need 3-phase installation.

How to design electrical installations online in 4 steps

1

Determine number of rooms

Start by adding rooms: kitchen, living room, bedrooms, bathroom. Each room will have dedicated circuits.

2

Add electrical circuits

Assign circuits to rooms: sockets (B16, 2.5mm²), lighting (B10, 1.5mm²), appliances. The program automatically selects protections.

3

Design the distribution board

Use the visual distribution board editor. Arrange circuit breakers on DIN rails and check the single-line diagram.

4

Export project to PDF

Generate complete documentation: circuit list, distribution board diagram, power balance, material list.

FAQ

What is the best free electrical design software?+

Electro Planner is a free online electrical design software. It offers automatic B10/B16 circuit breaker selection, visual distribution board editor, symmetric phase distribution, and PDF documentation export. Works in browser without installation.

Can you design electrical installations online without installing software?+

Yes, Electro Planner is electrical design software that works entirely online. Just open the page in your browser and you can start designing immediately. No downloads or installation required.

How to start designing home electrical?+

Start by determining the number of rooms and electrical devices. Then add circuits: sockets (B16), lighting (B10), dedicated circuits for appliances (hob, oven, dishwasher). Electro Planner automatically selects protections and cable sizes.

Does the electrical design software generate PDF documentation?+

Yes, after completing the project you can generate complete PDF documentation containing: list of all circuits, distribution board diagram, phase power balance, material list. Documentation is ready to hand to the electrician.

Does the software support 3-phase installation design?+

Yes, Electro Planner supports both single-phase and 3-phase installations. The program automatically distributes load across phases L1, L2, and L3, ensuring symmetry and optimal use of connection power.
