Plan your fuse box, module by module
FusePlan is a free, browser-based editor for electrical sub-distribution boards. Drag breakers, RCDs and surge protection onto DIN rails, watch the capacity per row, and export a tidy parts list.
2 × 12 TECompact: one field, two rows of 12 modules. Good for a flat or a small house.View configuration
Drag-and-drop rails
Build each row by dropping modules onto the DIN rail. FusePlan tracks the used TE (Teilungseinheiten) and flags an overloaded rail before you order.
Real component widths
LS/MCBs, FI/RCDs and surge protection use their true module widths, so the layout matches the hardware you will actually mount.
Parts list & sharing
Turn a layout into a shopping list, save projects locally, and share a plan via a link. No account needed.
How it works
1. Start from a preset or a blank board
Pick a ready-made configuration close to the enclosure size you already have, or start from an empty board and build up rows as you go.
2. Place real components
Drag breakers, RCDs and surge protection out of the toolbox. Each module keeps its true width, so a layout that fits on the rail here fits on the rail at home.
3. Export your parts list
Once the board is full, turn it into a shopping list with the exact quantities and module types, ready to check against your own order or an electrician’s quote.
