PanelMaster: Breaker Panel Map

Stop guessing which breaker does what. PanelMaster turns your electrical panel into a clear, searchable map of every circuit.

Build your panel the way it really looks, walk through the breakers once, and you have a directory you can print, scan and share. It suits homeowners, landlords and electricians, and works for North American panels and European DIN rail boards.

WHAT YOU CAN DO
- Lay out North American two-column panels and DIN rail boards, including subpanels, RCDs and RCBOs
- Mapping mode: turn off a breaker, tick the rooms that lost power, move to the next one
- Trace any load through its breaker and subpanels back to the main panel
- Search rooms, loads, breaker labels, panels and notes in one place
- Print a panel directory label in A4, Letter or a small half-page size
- Stick a QR label on the panel and scan it to open the right map
- Create customer PDF reports with your company details
- Keep photos with sites, panels and breakers, with undo and a change history
- Export CSV and back up to JSON. Works fully offline, with no account
