How We Work

Our Subpanel Service Process

Every property has different power needs, so we start with an assessment before recommending a fix.

01Step 1

Load Assessment

We look at your current main panel, existing circuits, and what you're trying to power to figure out what capacity you actually need.

02Step 2

Plan and Recommendation

Based on that assessment, we recommend installation, replacement, or upgrade options that fit your home and budget.

03Step 3

Installation or Repair

We complete the wiring, mounting, and connections, following local code requirements for a safe, reliable setup.

04Step 4

Testing and Walkthrough

Once the work is done, we test the subpanel under load and walk you through what was installed and how it operates.

Frequently asked

Subpanel Service Questions

Get clear answers about subpanel installation & services, preparation, timing, maintenance, and what to expect before requesting an estimate.

How do I know if I need a subpanel?

If your main panel is running out of open breaker slots, or you're adding power to a garage, shed, or addition, a subpanel lets you extend capacity without replacing your entire electrical system.

Can you add a subpanel to a detached garage or shed?

Yes, we regularly install subpanels for detached garages, workshops, and outbuildings, running the necessary wiring from your main panel to supply power where you need it.

What causes a subpanel to overload or trip repeatedly?

Overloading usually happens when a subpanel is supplying more circuits or appliances than it was sized for. We troubleshoot the panel and wiring to find the cause and correct it.

Is subpanel replacement different from an upgrade?

Replacement swaps out a failing or outdated subpanel for a new one of similar size, while an upgrade increases capacity to support additional circuits or higher demand equipment.

Will subpanel work bring my system up to code?

Any subpanel installation or repair we complete is done to meet current electrical code requirements, which also improves the overall safety of your home's system.

Do you serve areas outside Neenah?

We provide subpanel installation and repair throughout Neenah, Appleton, Oshkosh, Kaukauna, De Pere, and Green Bay.

How long does a typical subpanel installation take?

Most residential subpanel installations are completed in a single day, though timing depends on the wiring run and whether we're adding a subpanel to a detached structure.

Can a subpanel support future additions like an EV charger?

Yes, a properly sized subpanel can be planned with extra capacity for future needs such as an EV charger or generator connection.
