## Description

Calculate electrical panel loads instantly with NEC 80 percent rule checks — built for electricians and engineers.

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.
