Transfer Switch Installation in Prescott, AZ

A transfer switch is a key part of a safe backup power setup. It helps prevent backfeeding and keeps your electrical system protected when a generator is running.

If you already have a generator and want a safer, cleaner way to power your home during an outage, we can evaluate your setup and recommend the right transfer switch solution.

Standby vs Portable Generators

Home standby generators are permanently installed and can provide automatic backup power when the utility goes out.

Portable generators can be a practical option for short outages or limited power needs, but the safest home setups still require the right connection method and planning.

If you tell us what you want to power and how long you want coverage, we will recommend the best fit and explain the tradeoffs clearly.

Frequently Asked Questions

It depends on what you want to run during an outage, plus local conditions. Many homeowners choose an essential circuit setup for things like the fridge, lights, internet, and a few outlets, while others want broader coverage that can include larger loads. In Prescott Valley, elevation is around 5,000 feet, and generator output can drop at higher elevations, so sizing needs to account for that derating. The most accurate approach is a load assessment that lists your priorities and matches them to a properly sized system.

Yes. A transfer switch, or an approved interlock solution, is the standard way to connect generator power to home circuits safely. It prevents backfeeding, which is when generator power flows back into utility lines and creates serious shock and fire hazards. Generac specifically warns against backfeeding, and utility guidance also highlights the danger of this practice because voltage can be stepped up through transformers. If you want a safe, code-compliant setup that an electrician can inspect and service, a transfer switch is the right path.

Often yes, but it depends on the AC size, the starting surge, and what else you want powered at the same time. Air conditioners typically require a significantly higher burst of power to start than they do to maintain operation, so sizing is based on both running watts and starting watts. Some homes use load management or a soft start to reduce the startup demand and make AC backup more practical. The safest way to determine this is to review the AC nameplate, calculate the total load you want to back up, and size the generator for real-world conditions.

Yes. We install Generac home standby generators in Prescott Valley and provide ongoing service for supported systems, including maintenance, troubleshooting, and repairs. The goal is a setup that starts reliably, transfers power safely, and is sized so it does not struggle under load. If you are deciding between essential circuit backup and whole-home coverage, we can walk you through options, fuel considerations, and placement requirements so you end up with a dependable system that fits your actual power usage.

The on-site installation can often be completed in a few hours; however, the entire process usually takes longer, as preparation and approvals can take several weeks. Timing depends on the site layout, generator placement, electrical work, fuel connections, utility coordination, and permitting. Generac notes that the installation itself typically takes hours, while permits and other preparatory steps impact the overall timeline. In Prescott Valley, permit submissions and scheduling can also impact the calendar, so after the assessment, we provide you with a clear scope and schedule.

Yes. If your setup feels questionable, it is worth addressing before the next outage. We can inspect the generator’s connection, assess the risk of backfeeding, verify the inlet and breaker setup, and recommend a safer transfer switch or interlock solution that matches your panel and generator. This is especially important if someone has been using a cord into a dryer outlet or any improvised connection, since backfeeding can be dangerous and is not an acceptable long-term solution. We focus on making it safe, reliable, and easy to use.
