Chart
Home electrification load stack chart
Visualize how major electrification loads such as EV charging, heat pumps, water heating, cooking, and laundry can crowd a residential service.
Does not calculate legal demand, approve service capacity, or size equipment.
load stack
Load stack bands
Use the bands as a conceptual companion to the calculators, not as a demand calculation.
Can be managed or reduced by EVSE setting.
Resistance heat can dominate the service stack.
Voltage and element operation affect impact.
Existing major loads set the base context.
Nameplate and local rules matter.
Decision table
Show how major electrification loads stack conceptually before users run service-capacity or load-list arithmetic.
Scroll sideways to keep row labels aligned with hidden columns.
| Condition | Chart reading | Next check | Boundary |
|---|---|---|---|
| 100 A service with EVSE | High chance of load-management review | EV panel chart | No capacity result |
| Heat pump with large backup heat | Resistance heat can dominate the stack | Backup heat chart | No HVAC sizing |
| HPWH or induction added | Panel space and load both matter | Service capacity calculator | No circuit approval |
| All-electric renovation | Treat as a whole-service plan | Load list calculator | No service approval |
Notes
- Treat this chart as a planning and conversation aid only.
- Confirm current utility requirements, product markings, manufacturer instructions, and local authority requirements before field work.
- Use the linked calculator or table when the task needs project-specific arithmetic.
