About Panel Schedules

A panel schedule is a detailed document showing all circuits in an electrical panel, including their loads, breaker sizes, and wire specifications. Required for electrical permits and inspections.

NEC 2023 Compliance

Article 220 - Load Calculations
Article 240 - Overcurrent Protection
Article 310 - Conductor Sizing
Demand factors reduce calculated load based on diversity

Design Tips

Balance loads between phases for efficiency
Include 25% spare capacity for future expansion
Mark continuous loads (3+ hours) for proper breaker sizing
Group circuits logically (lighting, receptacles, equipment)

Key Formulas

Single-Phase: I = VA / V:

I = \frac{VA}{V}

Three-Phase: I = VA / (sqrt(3) x V):

I = \frac{VA}{\sqrt{3} \times V}

Continuous: I x 1.25:

I_{adj} = I \times 1.25
