BreakerCheck

BreakerCheck is a local tool for preliminary planning of electrical loads for single-phase lines.

Create projects, describe rooms and lines, fill out a device catalog, and compare load scenarios—all without the internet, accounts, or ads.

Features:
• Projects with voltage, simultaneity factor, and user reserve
• Rooms, lines, and socket groups
• Device catalog: power, mode, duty cycle, and starting factor
• Four start-up scenarios: normal day, kitchen, workshop, emergency power
• Calculation of active, estimated, and peak power, current, and circuit breaker load percentage
• Warnings for overload, low reserve, inrush currents, and unlinked devices
• Global project search, duplication, and deletion with Undo
• JSON backup with preview (Replace/Merge)
• PDF report via system file selection (SAF)
• Light/dark theme and Dynamic Color

Important: BreakerCheck does not replace an electrical project or calculation by a qualified electrician. The result depends on the entered data and does not take into account all Electrical Installation Code (PUE) requirements, wiring condition, or the characteristics of protective devices.
