NEC Article 220 — Panel Schedule Generator

NEC Panel Schedule Generator

A panel schedule documents every circuit in a distribution board: load watts, voltage, phase, demand factor, and calculated amperage. FrameAI generates one automatically from your existing Excel file — applying NEC Article 220.11 demand factors and NEC 220.12 lighting demand tables so the output is code-compliant, not just a circuit list.

NEC Art. 220.11 Demand Calculations

NEC 220.11 requires branch circuit loads to be computed from the load on each circuit. For lighting and appliance loads, NEC 220.12 references Table 220.12 for square-foot demand factors. FrameAI applies the correct factors and reports them per panel.

Feeder Summary

After branch circuit demand, FrameAI sums each panel to produce a feeder demand figure. Largest motor at 125% per NEC 430.24, receptacle bank first 10 kVA at 100% + remainder at 50% per NEC 220.42.
