Generator transfer switch handoff worksheet
Use this worksheet to define essential loads and site constraints before comparing standby generators, portable generators, manual transfer switches, automatic transfer switches, or interlock options.
Backup power goal
| Item | Notes |
|---|---|
| Outage concern | Short nuisance outages / long storm outages / medical equipment / sump pump / home office / other |
| Backup path being considered | Portable generator / standby generator / battery / not sure |
| Transfer equipment being discussed | Manual transfer switch / automatic transfer switch / interlock / not sure |
| Fuel source | Gasoline / propane / natural gas / diesel / battery / not decided |
| Permit or inspection contact | |
| Electrician, generator dealer, or utility contact |
Essential-load list
List only loads that must run during an outage. Startup watts and locked-rotor current should be checked by a qualified person or from equipment nameplates/manuals.
| Load | Location or circuit | Running watts/amps if known | Startup concern | Essential? |
|---|---|---|---|---|
| Refrigerator or freezer | Yes / no / unknown | |||
| Sump pump | Yes / no / unknown | |||
| Well pump | Yes / no / unknown | |||
| Furnace blower, boiler, or HVAC controls | Yes / no / unknown | |||
| Heat pump, AC, or mini-split | Yes / no / unknown | |||
| Medical or accessibility equipment | Yes / no / unknown | |||
| Internet, lighting, or small appliance circuit | Yes / no / unknown | |||
| EV charger or large optional load | Yes / no / unknown |
Panel and site notes for the electrician
| Visible note | Details |
|---|---|
| Main panel amperage from label if visible | |
| Main breaker size if visible without removing covers | |
| Subpanels present | Yes / no / unknown |
| Utility meter and service disconnect location | |
| Clear wall space near panel | |
| Outdoor generator location options | |
| Distance from windows, doors, vents, and neighbors | |
| Fuel line, propane tank, or gasoline storage constraints | |
| Photos taken from a safe distance | Yes / no |
Transfer equipment questions
- Which loads will be backed up, and which loads will be intentionally excluded?
- Will the transfer equipment be listed and approved for the panel and service arrangement?
- Is load shedding, generator management, or soft-start equipment needed for HVAC or pumps?
- What permits, inspections, utility notifications, and fuel inspections apply locally?
- Where can the generator run without carbon monoxide entering the home?
- How will the system prevent utility backfeed every time it is used?
- What user steps are required during an outage and after utility power returns?

Stop conditions
- Someone suggests a male-to-male cord, dryer outlet backfeed, suicide cord, or improvised generator connection.
- The plan allows the generator to run in a garage, attached carport, basement, crawlspace, near open windows, or near intake vents.
- The transfer equipment is not matched to the panel, service, generator, or local code requirements.
- Essential loads are being promised without checking startup current, fuel limits, or load management.
- The quote skips permits, inspections, grounding/bonding questions, utility isolation, or fuel work.
- Any panel work would require removing covers or touching energized parts.
