How It Works

Our Generator Installation Process

We keep the process straightforward. Here is what to expect from first contact to a fully operational generator.

01Step 1

Site Assessment

We visit your property to evaluate your panel, fuel source options, and the best placement for the generator unit based on local code requirements.

02Step 2

Equipment Selection

We help you choose a generator sized correctly for your home or business, whether you need to power essential circuits or your entire property.

03Step 3

Installation Day

Our team handles all electrical work, including transfer switch installation, wiring, and connection to your panel. No subcontractors needed.

04Step 4

Testing and Handoff

We test the system under load, confirm the automatic transfer switch activates correctly, and walk you through basic operation before we leave.

Frequently asked

Generator Installation Questions

Find clear answers about service options, scheduling, preparation, and what to expect before you request an estimate.

Q1

What size generator do I need for my home?

It depends on what you want to power. A whole-home generator typically runs between 20kW and 22kW for an average-sized house. We assess your panel and load requirements during the site visit to give you a clear recommendation.

Q2

Do you install generators throughout Northeast Wisconsin?

Yes. We serve Neenah, Appleton, Oshkosh, Kaukauna, De Pere, Green Bay, and the surrounding areas. If you are unsure whether we cover your location, give us a call at (920) 709-9132.

Q3

What fuel type do standby generators use?

Most whole-home standby generators run on natural gas or propane. We can help you determine which is more practical based on what utilities are available at your property.

Q4

Will my panel need to be upgraded before installation?

Not always, but sometimes. If your current panel is older or does not have enough capacity, we may recommend an upgrade first. We check this during the site assessment so there are no surprises.

Q5

What is an automatic transfer switch and do I need one?

An automatic transfer switch detects when utility power fails and switches your home to generator power without you doing anything. For a standby generator, yes, you need one. We include the transfer switch as part of every whole-home installation.

Q6

How long does a generator installation take?

Most residential installations are completed in one day. Larger properties or those requiring panel work may take longer. We give you a realistic timeline when we quote the job.

Q7

Is a permit required for generator installation in Wisconsin?

Yes, electrical permits are required. Brey Electric pulls the necessary permits and ensures the installation meets Wisconsin electrical code so the work is done legally and safely.

Q8

Can you install a generator for a commercial property?

Yes. We work on both residential and commercial generator installations across Northeast Wisconsin. Commercial installs vary in scope, so contact us to discuss your specific needs.
