What does whole-home coverage mean?
Whole-home coverage describes the connection arrangement, not a promise that every appliance will run at the same time. The system still has to be planned around the home’s real loads.
That distinction matters because the transfer equipment and generator size have to match the actual demand.
Which loads are essential to this household?
Decide which loads are most important to the household, then have their actual demands assessed. Heating or cooling equipment, refrigeration, lighting and pumps may matter, depending on what the home uses.
Keep a separate plan for critical medical power needs. A residential standby generator does not establish uninterrupted power or a medical-reliability guarantee.
How do circuit selection and load management differ?
Circuit selection and load management solve different problems. One narrows the powered circuits, while the other can support broader coverage through designed controls.
The right choice depends on what the home needs and what the assessment confirms.
| Coverage approach | Tradeoff | What must be assessed |
|---|---|---|
| Selected essential circuits | Smaller coverage but more focused on priority loads | Which circuits truly matter to the household |
| Broader coverage with designed load management | Can support more of the home by controlling demand | How the loads will be managed and what the system can support |
What is needed to choose?
A load assessment and a written covered-load schedule are needed before purchase. That gives the homeowner a clear basis for comparing options.
Without that step, the choice is too dependent on guesswork.
