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.

Chart boundary

Does not calculate legal demand, approve service capacity, or size equipment.

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.

Backup heat20-63 A

Resistance heat can dominate the service stack.

HPWH / water5-25 A

Voltage and element operation affect impact.

Cooking / dryer20-50 A

Existing major loads set the base context.

Hot tub / suiteproject-specific

Nameplate and local rules matter.

Decision reference

Show how major electrification loads stack conceptually before users run service-capacity or load-list arithmetic.

Reference basis: BC Hydro home electrical capacity information and Canadian residential electrical load-management resources.

Use notes

  • Use 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.
