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.
