This page is designed to help you find out whether FusePlan.app is good and if it is the right choice for you.
FusePlan is a browser-based planner for electrical sub-distribution boards (Unterverteilung). You drag real circuit breakers, RCDs and surge protection modules onto a DIN rail, and the layout tracks the actual module widths and the used TE (Teilungseinheiten) per row, so what fits on screen fits in the real enclosure. Once the board is full, FusePlan turns it into a parts list with exact quantities, ready to check against an order or an electrician's quote.
There's also a labeling assistant: type a circuit list once and it numbers every device in reading order and generates label strips sized to the real modules.
It runs entirely in the browser. Nothing is uploaded, there's no account and no tracking. Projects save locally and can be shared through a link.

FusePlan started as a small tool to sketch the layout of a home sub-distribution board instead of using spreadsheets or paper. It's built and maintained by one developer as a side project. It's a planning aid, not a replacement for a qualified electrician. Final installation and sign-off still belong to a professional.
Status: early beta. Some features, including buying the parts list directly, are still being built.
FusePlan is free and stays free. It isn't a shop: the parts list links out to Amazon's own product pages, you buy there at Amazon's normal price, and FusePlan earns a small commission as an Amazon Associate. That affiliate commission is the only revenue. There's no subscription and no paywalled tier.
FusePlan plans an electrical sub-distribution board using the real dimensions of the hardware you'd actually buy. Drop breakers, RCDs and surge protection onto a DIN rail, and it tracks the used TE (Teilungseinheiten) per row against real Hager, ABB and Schneider module widths, not a generic box. From that layout it generates three things most planning tools don't: a parts list with exact quantities, an auto-drawn one-line wiring schematic, and printable label strips for the panel door. It's free, runs entirely in the browser, and doesn't ask for an account.
The realistic alternatives are a spreadsheet, a sheet of paper, or professional electrical CAD like EPLAN or AutoCAD Electrical. A spreadsheet doesn't know how wide an RCD actually is, and professional CAD is built for cabinet designers, not a homeowner planning one board. FusePlan sits in between: built for exactly this one job, free, and usable without training.
Homeowners and DIYers planning or upgrading a sub-distribution board for their own house, plus electricians who want a fast way to lay out a board and generate a parts list. The site is bilingual (English/German), and the terminology throughout (Unterverteilung, TE, DIN VDE 0100) points at German-speaking countries as the main audience, though FusePlan doesn't track visitors, so there's no usage data to confirm that.
Astro for the site, React and TypeScript for the planner itself (a separate library,
subpanel-editor, that the site imports), Tailwind CSS for styling, Vite for the
library build, and Playwright for testing and tooling. It deploys as a static site on
Cloudflare Pages.
None to name. FusePlan has no accounts, doesn't track visitors, and collects no data that would say who's using it, so there's no way to know who its biggest users are. That's by design, not an oversight.
