About this app

Filling out a panel schedule and need to check if total connected load passes the NEC 80% continuous load rule? Add your circuits, see kW totals, and get an instant panel utilization percentage — before the inspector shows up. Add circuits with name, voltage, phase, and amperage. The app calculates each circuit's watt load, tracks total connected load, and checks the 80% continuous load rule against your panel rating. WHAT IT CALCULATES: - Total connected load in W and kW - Per-circuit watt load from volts, amps, and phase - Panel utilization percentage with color-coded status - Total amperage at your panel voltage - Overload warning when utilization passes 80% VOLTAGE CONFIGURATIONS: - 120V, 208V, 240V, 277V, 480V - Single phase and three phase KEY FEATURES: - Editable panel schedule with swipe-to-delete and Clear All - NEC 80% continuous load rule check against your main breaker - Enter any main breaker amperage and panel voltage - Watt totals per circuit, W/kW total for the panel - Works completely offline Built for licensed electricians, electrical engineers, and building inspectors.
