The project
What the work involves.
Ice storms, severe thunderstorms, and heavy snowfall can interrupt electrical service. A standby generator and automatic transfer switch provide backup power to the circuits selected for your home. We assess the electrical load, fuel supply and placement before planning the installation.
A typical whole-home generator installation takes 1-2 days. We start with a site assessment to determine the right generator size based on your home's electrical load, fuel source availability, and placement options. We handle everything from the concrete pad to the electrical connections, transfer switch, and fuel line. Every installation includes full testing under simulated outage conditions and a walkthrough so you understand how your system works.
Scope
Included in the work.
- Generac whole-home standby generator installation
- Automatic transfer switch installation
- Natural gas or propane fuel line connection
- 200A/400A panel integration
- Load management and critical circuit selection
- Concrete pad preparation and placement
- Municipal permit acquisition and inspection
- Post-installation testing and owner training
- Annual maintenance plans available
- Existing generator repair and maintenance
At your home
From assessment to inspection.
Load Assessment
We calculate your home's electrical load to recommend the right generator size — typically 22kW to 26kW for most homes, larger for homes with electric heat or EV chargers.
Site Planning
We identify the optimal placement considering setback requirements, fuel source proximity, noise considerations, and service access.
Permits & Utility Coordination
We pull all required electrical and gas permits and coordinate with your utility for the interconnection.
Installation
Concrete pad, generator placement, automatic transfer switch, fuel line connection, and full electrical integration — typically completed in 1-2 days.
Testing & Training
We simulate a power outage to verify automatic start, transfer, and full-load operation. We walk you through maintenance schedules and operation.
Before we start
Your questions.
How much does a whole-home generator cost in Wisconsin?
It depends on the size of the unit, the fuel type, and site conditions — the generator, transfer switch, installation labor, concrete pad, and permits are all part of the job. We size the unit for your home during a free assessment and give you an exact figure before any work begins.
How long does generator installation take?
Most residential generator installations take 1-2 days once the equipment arrives. Lead time for equipment ordering is typically 2-4 weeks.
Do I need a permit for a generator in Wisconsin?
Yes. Wisconsin requires both an electrical permit for the transfer switch and wiring, and often a gas permit for the fuel line connection. We handle all permitting as part of the installation.
How often does a standby generator need maintenance?
Standby generators should be professionally serviced annually — oil change, air filter, spark plugs, battery check, and transfer switch testing. Most units self-exercise weekly to stay ready.
