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

ItemNotes
Outage concernShort nuisance outages / long storm outages / medical equipment / sump pump / home office / other
Backup path being consideredPortable generator / standby generator / battery / not sure
Transfer equipment being discussedManual transfer switch / automatic transfer switch / interlock / not sure
Fuel sourceGasoline / 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.

LoadLocation or circuitRunning watts/amps if knownStartup concernEssential?
Refrigerator or freezerYes / no / unknown
Sump pumpYes / no / unknown
Well pumpYes / no / unknown
Furnace blower, boiler, or HVAC controlsYes / no / unknown
Heat pump, AC, or mini-splitYes / no / unknown
Medical or accessibility equipmentYes / no / unknown
Internet, lighting, or small appliance circuitYes / no / unknown
EV charger or large optional loadYes / no / unknown

Panel and site notes for the electrician

Main panel amperage from label if visible
Main breaker size if visible without removing covers
Subpanels presentYes / 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

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.
