Stop guessing which breaker controls what. Every home and building has an electrical panel. Most have a label stuck inside the door that's illegible, incomplete, or wrong. Breaker Box changes that — a circuit breaker directory for every panel, organized by room, printable as a professional legend or panel schedule. LABEL EVERY CIRCUIT Assign notes, rooms, and fixtures to each breaker, so the labels on the door finally match the wiring behind it. Every breaker type is supported: tandem splits, multi-pole (1-, 2-, and 3-pole), GFCI, and HACR. Track wire gauge and size per circuit. Set custom phase colors for single-phase and three-phase panels. ORGANIZE BY ROOM Map every circuit to the rooms and fixtures it powers. When someone asks "which breaker controls the master bath GFI?", you'll have the answer instantly. PDF LEGENDS & PRINT Export a panel legend as a PDF sized to fit a sleeve insert or tape inside the door. Adjust font scale per breaker for a clean, professional result. It replaces the printable breaker box label template or Excel panel schedule you would otherwise download: the directory you built on screen becomes the label sheet, sized to your panel, and it stays current when a circuit changes. FOR ELECTRICIANS A panel schedule for every job. Subpanels, 3-phase panels, tandem breakers and per-circuit wire gauge are all documented, the labels print to size, and the client handoff is a PDF.
