Design your electrical panel in 10 minutes — and build it yourself, step by step
Answer simple questions about your home and get a complete panel design: realistic layout, shopping list and step-by-step assembly instructions.
What you will need
The rating of your main breaker
It is the topmost breaker in the panel, usually standing on its own. The marking reads something like C40 or B25 — the number is the rating in amperes.
How many wires come into your home
Count the wires in the cable feeding your panel: two or three means one phase, four or five means three phases. You do not need to know the term.
A list of your large appliances
Electric stove, water heater, washing machine, dishwasher, air conditioner, EV charger — anything on its own heavy cable. An approximate power in watts is enough.
Do not know your main breaker rating or your earthing system? Both questions have an “I do not know” option — the wizard estimates what it can and says plainly what an electrician must check.
How it works

Answer questions
Tell us about your rooms, appliances and incoming supply. No jargon — every term is explained.

Get your panel
The generator picks breakers, RCDs and cable sizes and lays them out on DIN rails by the rules of your region.

Built on real standards
Every generated panel is checked by a rule engine built on the EU HD 60364 series and the CIS wiring regulations (PUE). When your situation goes beyond the rules, we say so instead of guessing.
A licensed electrician must review and approve the final installation. PlanMyPanel prepares the design — it does not replace professional work.
Frequently asked questions
Do I still need an electrician?
Yes. PlanMyPanel produces a correct design and shopping list, but a licensed electrician must review and approve the final assembly and connection.
Which standards does it follow?
Two switchable profiles: the European HD 60364 series and the CIS wiring regulations (PUE). Where the readings differ, we follow the stricter one.
Is it free?
Yes. The app runs entirely in your browser and is free to use.
Where is my project stored?
Locally in your browser (localStorage). You can export any project as a JSON file and import it on another device.
Can I change the generated panel?
Yes. Open the project in the editor: add, replace or move devices — the rule engine re-checks the panel live.
Does it work for a 3-phase supply?
Yes. The wizard supports 1- and 3-phase supplies, and the generator balances circuit groups across the phases.
