Breakerly

The kettle, the microwave and the air fryer are on, and you're about to start the dishwasher. Will the kitchen breaker hold, or does the whole kitchen go dark in forty seconds? Breakerly answers that before you press the button. It's a digital twin of your consumer unit. You draw your panel once — main switch, every breaker with its rating and curve (B16, C20, B32…) and what plugs in where — and Breakerly simulates it live. It uses the same time-current behaviour real miniature circuit breakers follow, not a simple "watts ÷ volts" sum. ⚡ A LIVE PANEL, NOT A LIST • Your breakers drawn the way they look on the wall: levers, colour caps, label strip and a load bar with a status LED on each one • An analogue ammeter for the whole house, plus kW and running cost per hour at your day or night rate • Tap a breaker to see its load, its headroom in watts and where it sits on its own trip curve right now • Timers count down on kettles, microwaves and washing machines, and the load drops when they finish 🔥 IT KNOWS WHEN A BREAKER REALLY TRIPS • Follows the IEC 60898 behaviour: holds below 1.13× its rating, trips on heat within minutes to seconds above that, and trips instantly in the magnetic band (B 3–5×, C 5–10×, D 10–20×) • Counts timed appliances: "Past the trip threshold, but it holds — the kettle finishes in 1:52" • Remembers heat, so a breaker that just carried an overload trips sooner the second time • Start-up surge of motors and compressors (vacuum, fridge, compressor) can trip instantly, and Breakerly warns you about it • Optional live trips: leave an overload running and the breaker really opens, and everything on it goes off, just like at home 🔌 "PLUG SOMETHING IN" — A VERDICT BEFORE YOU SWITCH ON • Every appliance that's off gets a verdict for right now: Safe, Tight, Over rating, Surge risk or "Trips in 43 s" • Portable things show a safer circuit: "→ safe on Bathroom (24%)" • If something will trip, Breakerly offers a fix: use another socket, or make room by carrying the kettle and the air fryer to other circuits in one tap 🎄 SCENARIOS — PLAN THE BIG MOMENTS Holiday dinner, a cold winter evening, the morning rush: pick what you want running together and Breakerly: 1. Checks every breaker and the main switch with everything on at once 2. Moves portable appliances to other socket circuits to flatten the peaks 3. If it still doesn't fit, schedules the rest in waves, each at the earliest moment that's safe, on a clear timeline Then start wave 1 on the live panel with one button. 🌙 NIGHT PLAN — CHEAP-RATE WITHOUT TRIPS Pick the jobs that can wait (washing machine, dryer, dishwasher, water heater, EV or e-bike charger). Breakerly finds a start time for each inside your cheap-rate window without ever overloading a breaker or the house limit. It shows the plan, the load profile, and how much you save tonight and over a year. 🧰 MADE FOR REAL HOMES • 60 typical appliances with watts, start-up surge, run time and average draw — edit any of them to match the rating plate • Any number of circuits: sockets, lighting and dedicated lines, ratings 6–63 A, curves B, C and D • 110–240 V, main switch 25–100 A, plus an optional supply power limit (smart-meter or limiter caps) • Any currency, your own day and night rates and window • Share a panel report or tonight's plan as text • Light and dark themes 🔒 PRIVATE AND OFFLINE No account, no ads, no tracking, no internet needed. Everything stays on your phone. Breakerly is a planning aid, not electrical advice. Real breakers vary by make, age and temperature. If a breaker trips often or anything feels hot, call a qualified electrician.
