What Size Generator Does a House Need?

ABR Electric field work related to this homeowner guide

The short answer

Size a generator around the equipment you want to run, rather than square footage alone.

Key points

  • Priority loads: list refrigeration, lighting, medical equipment, air conditioning, and other essentials.
  • Starting demand: motors can need more power to start than to keep running.
  • Load planning: decide what must operate together and what can be managed.
  • Installation scope: confirm fuel supply, transfer equipment, placement, permits, and testing.
Bottom line: The right generator supports your agreed backup plan. A larger unit does not replace careful load planning.

Next step

Give ABR Electric your priority list and ask for a sizing evaluation and complete installed quote.
