Residential project planning
Generator connection work gives a homeowner a controlled way to supply selected circuits from compatible portable equipment. The electrical scope may include an inlet and a transfer switch or permitted interlock, plus planning for essential loads or battery-backup connections.

Field briefing / Fairfax, VA
Jurisdiction confirmed by property address
Scope first
Compare a manual transfer switch with an interlock based on the panel, selected circuits, and permitted configuration.
Choose the essential loads to support and a practical outdoor inlet location with a workable circuit route.

Address-specific planning
A Fairfax backup-power estimate separates jurisdiction from equipment design. The address identifies City or County review, while the customer-owned portable source, essential circuits, panel compatibility, and inlet route define the electrical work.
Mantua, Fairfax City, and Fairfax Station show why a Fairfax label does not identify one authority or property layout. We check whether the selected loads are in the main panel or a subpanel, whether the route reaches an attached or detached area, and whether manual transfer equipment or a permitted interlock fits the panel. City properties use City of Fairfax Code Administration; County properties use Fairfax County Land Development Services.

Property-specific answers
City of Fairfax Code Administration handles properties inside the independent city. Fairfax County Land Development Services handles County addresses, so the exact property boundary is confirmed before the permit scope is assigned.
Possibly, but the feeder, overcurrent protection, panel relationship, and transfer location must be reviewed. We map where each requested circuit originates before deciding how the compatible backup source can serve it.
