Garage or workshop
A group of tool, lighting and equipment circuits may be better served from a local subpanel. Share the equipment specifications, including anything with a motor or substantial startup demand.

SACRAMENTO / SUBPANELS
A subpanel can put the circuits for a garage, workshop or addition where they are needed. Menderix plans the feeder, equipment location and circuit layout around the project, after checking that the existing electrical service can support the proposed loads.

KNOW WHAT A SUBPANEL DOES
A subpanel distributes power from an existing supply to a group of circuits. It can make a new work area easier to serve and organize. The feeder and upstream service still limit how much electrical demand the installation can support.
We review the planned loads before choosing the feeder and enclosure. If the main service needs to change, that is a separate part of the plan. A larger box alone will not resolve a capacity shortage.
COMMON PROJECTS
A group of tool, lighting and equipment circuits may be better served from a local subpanel. Share the equipment specifications, including anything with a motor or substantial startup demand.
New rooms may need several circuits. We compare the available main-panel space and possible routes before deciding whether a subpanel is useful.
Distance, access and the route between buildings become important. Underground work and the building’s intended use can change the design and installation scope.

CHOOSE A WORKABLE LOCATION
The subpanel should be accessible after the project is finished. A location that looks clear during construction may later be blocked by shelving, a workbench or stored equipment. We plan the required working space around the room’s final layout.
The feeder route also matters. A short visible run in a garage differs from a route through finished rooms or beneath a paved yard. We discuss those options and the likely disturbance before the equipment location is fixed.
WHAT WE REVIEW
| Part of the project | Why it matters |
|---|---|
| Existing electrical service | Determines whether the added demand can be supported and whether upstream work is needed. |
| Feeder route and distance | Affects conductor and raceway design, access, excavation and restoration. |
| Equipment and environment | The enclosure and components must suit the location and the circuits they serve. |
| Grounding and protection | The installation needs the appropriate grounding, bonding and protective devices for its configuration. |
| Circuit identification | A useful directory makes it possible to identify the area or equipment served by each breaker. |
Equipment selection follows the site assessment and applicable requirements. The installation details depend on the property and planned equipment.
BEFORE REQUESTING A QUOTE
A list of future equipment is more useful than asking for a particular panel rating without the project details.
Tell us about tools, EV charging, heating or other major loads. Include equipment you already know will be added later.
Photos of the main-panel exterior and the proposed subpanel area help us discuss the job. Keep all protective covers in place.
Mention driveways, patios, landscaping and finished walls along the possible route. The quote should identify excavation and surface-restoration responsibilities.
Confirm which approvals and coordination are included. Connecting the feeder will require planned electrical access and may interrupt power to part or all of the property.
Before you book
Here are a few details to help you plan the work. Call us if your property or equipment needs a closer look.
No. A subpanel distributes an existing supply to additional circuits. A service upgrade changes the available supply capacity and may involve the meter and utility. Some projects need both; others need only local distribution.
It may, if the feeder and upstream service have suitable capacity and the charging circuit meets the installation requirements. We assess the complete path back to the supply, not just the number of spare breaker spaces.
The intended circuits, calculated demand and feeder design determine the choice. Tell us what the area will run and any future equipment already planned so we can recommend a suitable installation.
Yes. We review the supply, building use, distance and available route. Trenching, grounding and restoration can be important parts of the quote, depending on the property.
Connecting new distribution equipment requires a planned interruption. We explain the affected area and coordinate the sequence with any applicable permit, inspection or utility requirements.
