A short first step
Where are you right now?
Choose the closest answer. You can send the essentials in a few minutes or open the complete guided journey if you want every decision explained.Capacity—not assumptions
A charger does not automatically mean a 200-amp upgrade.
The right answer comes from the charger, existing loads, panel space and how the home uses power. If you do not know your service size, that is okay—Seafield can review it later.Explore load-management answers →Managed charging may fit
For a qualifying loaded service, a compatible system such as the Siemens Inhab 60A Load Manager can manage EV demand when the home is using other large loads.
Panel or service work is justified
Recommend the larger electrical project only when equipment condition, space, capacity or future plans make it the appropriate path.
The connection is part of Seafield’s work
You do not need to provide the receptacle.
EV-rated receptacle
Where the charger uses a NEMA 14-50 connection, Seafield supplies and installs a device suited to continuous EV charging—not a light-duty range receptacle.
Hardwired charger
The selected charger connects directly to its dedicated circuit using the listed wiring method, conductor size and equipment settings.

Questions before an estimate
Clear answers for the electrical side.
Browse the full Ask Seafield library →Does an EV charger automatically require a 200-amp service?
No. Seafield reviews the service rating, calculated load, panel space, existing equipment and selected charger first. Some homes can support the circuit as they are; others may be candidates for compatible load management or service work.
Can an EV charger work with a 100-amp service?
Sometimes. A 100-amp rating alone does not answer the question. Existing heating, cooling, cooking, laundry and other loads must be considered. Where the equipment and conditions qualify, an energy-management system such as the Siemens Inhab 60A Load Manager may manage EV demand instead of assuming an immediate service upgrade.
Do I need to have an EV receptacle before Seafield arrives?
No. If the selected charger plugs in, Seafield supplies and installs the appropriate EV-charging-grade receptacle as part of the electrical scope. If it is hardwired, Seafield installs the listed connection required by the equipment.
Is a hardwired charger better than a NEMA 14-50 receptacle?
Both can be appropriate. The charger instructions, output, location and homeowner preference determine the connection. Hardwiring reduces connection points; a receptacle can offer flexibility. Every connection must match the installed circuit and equipment listing.
What should I send for an accurate first review?
A charger model or nameplate, the main breaker, the full panel, the route from panel to parking location and the parking area are the most useful photographs. If you are unsure what to photograph, send what you can and Seafield will identify the next step.
What if the charger is in a detached garage?
Detached garages require a separate site-specific review because trenching, a building feeder, conduit, disconnects and existing detached-building wiring can change the complete scope. This quick page focuses on chargers at the home, attached garage, exterior wall or carport.
