Panel Schedule

How do you want to build this panel schedule?

Start with a load calculation Recommended Enter the dwelling loads. Circuits, breakers, main and bus rating are filled in and balanced for you. Enter circuits manually Type each circuit, VA, breaker and pole yourself. Use Balance when you are done.

1Load Calculation

Single-family dwelling, NEC 2023 §220.82 Optional Method. Calculating fills the panel schedule below with balanced circuits and sets the main breaker and bus rating.

Service & General Loads §220.82(B)(1)–(2)

Service Voltage Floor Area (ft²)3 VA/ft² general lighting Small-Appliance Circuits1,500 VA each, min. 2 Laundry Circuits1,500 VA each, min. 1 Bathroom Receptacle Circuits20 A each, min. 1 (§210.11(C)(3)); load is in 3 VA/ft² Garage Adds a 20 A garage receptacle circuit (§210.11(C)(4))

Fixed Appliances (nameplate VA) §220.82(B)(3)

Garbage Disposal Dishwasher Microwave Garage Door Opener Refrigerator

Electric Heat (kW)Total nameplate kW

Separately Controlled Heaters4 or more: 40%; fewer: 65%

Supplemental heat interlocked with compressor

EV Charging 100%, outside the demand factor

EV Charger (VA)Charger nameplate. Breaker at 125% (§625.41): 9,600 VA → 50 A

Energy Storage Ready 2025 California Energy Code §150.0(s)

Identify the four backed-up circuits for a future battery (ESS) Refrigerator, lighting near the primary egress, a bedroom receptacle circuit and a kitchen small-appliance circuit. 100 A service: marked in the main panel. Above 100 A: placed in a 100 A ESS subpanel fed by a 60 A, 2-pole breaker.
