Install Backup Power Before the Next Outage

Professional Generac generator installation in Casper, from site prep and fuel hookup to transfer switch wiring and system commissioning.

Installing a Generac home standby generator means your home can ride out power outages without losing heat, water, or refrigeration. The installation process involves more than setting a unit on a pad-it requires running a fuel line, wiring an automatic transfer switch, pulling permits, and testing the system under load to confirm it starts and transfers power correctly. 7 stones electric handles Generac installations across Casper, coordinating the electrical work, fuel connections, and inspections needed to bring your backup power system online.

A typical installation starts with a site visit to confirm the best location for the generator, usually along an exterior wall with clearance from windows, doors, and air intakes. We pour or level a concrete pad to support the unit, connect it to your natural gas line or propane tank, and install an automatic transfer switch inside your electrical panel. The transfer switch monitors utility power and signals the generator to start within seconds of an outage, switching your home to backup power without manual intervention.

If you are ready to install a Generac generator at your Casper home, get in touch with 7 stones electric and we will walk you through the process from sizing to startup.

How the installation process unfolds from start to finish

Once you select a Generac model, 7 stones electric schedules a site visit to confirm placement, measure distances to your electrical panel and fuel source, and verify that local codes allow installation in your chosen location. We pull the necessary permits and coordinate inspections with the city of Casper. The generator is delivered to your home, and we prepare the installation site by pouring a concrete pad or installing a composite base that keeps the unit level and stable.

After the pad cures, we set the generator, connect the fuel line, and run conduit from the unit to your electrical panel. Inside the panel, we install the automatic transfer switch and wire it to the circuits you want backed up. Once all connections are complete, we fill the generator with oil, pressurize the fuel line, and run the startup sequence. You will hear the engine turn over, reach operating speed, and transfer power to your home within fifteen seconds.

We test the system under load by simulating an outage and confirming that the generator powers your selected circuits without voltage drops or error codes. The final step is a walkthrough where we show you the control panel, explain the weekly self-test cycle, and review the maintenance schedule. Installation typically takes one to two days depending on site conditions and whether trenching is required for fuel or electrical runs.

What homeowners want to know before installation day

Installing a backup generator is a permanent addition to your home, and most homeowners have practical questions about placement, permits, and what to prepare before the crew arrives. These answers cover the details that matter most during the installation process.

How long does Generac installation take?

Most installations take one to two days depending on site prep, fuel line routing, and whether the concrete pad needs time to cure. 7 stones electric coordinates all steps to minimize disruption.

Where should the generator be installed on my property?

Your Generac unit should sit at least five feet from windows, doors, and air intakes to prevent exhaust buildup. We choose a location that meets code, provides fuel access, and keeps electrical runs short.

Do I need a permit to install a Generac generator in Casper?

Yes, Generac installations require an electrical permit and inspection. 7 stones electric handles the permit application and schedules inspections with the city to keep your project on track.

Can I install a Generac generator if I use propane?

Yes, Generac generators can connect to an existing propane tank as long as the tank has sufficient capacity to supply the generator during extended runtime. We verify tank size and install the required regulator and shutoff valve.

What do I need to do before installation day?

You should clear the installation area of obstacles, confirm that your fuel source is accessible, and ensure someone is home to answer questions during the install. 7 stones electric handles everything else, including site prep and final testing.
