Beat Arizona Heat Outages — GenerLink Transfer Switch

Yes — GenerLink is approved by many utilities serving Arizona homeowners, including Arizona Public Service. Utility approval is required before installation, and GenerLink works directly with utilities across the state to maintain up-to-date approval status. Each utility has its own approval process, which may involve a simple notification or a brief inspection. Check the utility section above to see the specific approval status and instructions for your provider.

GenerLink installation in Arizona typically takes under 30 minutes when performed by a licensed electrician or utility-approved installer. Unlike traditional transfer switches that require rewiring your electrical panel, GenerLink co

ects directly to your utility meter socket — no internal wiring changes needed. Your installer will remove the meter, slide GenerLink into place, replace the meter, and co

ect your generator inlet. Most Arizona homeowners have their system fully operational the same day. Always use a licensed electrician familiar with your local Arizona codes and permit requirements.

The right generator size for a Arizona home depends on which appliances you need to power during an outage. Arizona homeowners dealing with monsoon storms and extreme heat should prioritize essential loads like HVAC, refrigerator, sump pump, and medical equipment. A 5,000–8,000 watt generator handles most essential loads for an average home, while larger homes or those with electric HVAC may need 10,000+ watts. GenerLink's MA23 model supports up to 7,500 ru

ing watts (30A) and the MA24 supports up to 10,000 ru

ing watts (40A).

Permit requirements vary by county and municipality in Arizona. In most cases, a licensed electrician handling the installation will obtain the necessary permits as part of the job. Some Arizona utilities require a simple notification rather than a formal permit, while others may require an inspection. We recommend contacting your local building department and your utility company before installation. The installers listed on this page are familiar with Arizona permit requirements and can guide you through the process.

With GenerLink and a properly sized generator, Arizona homeowners can power the appliances that matter most during monsoon storms and extreme heat outages. Essential loads typically include refrigerator (400–800W), window AC or furnace fan (500–1,500W), lights (200–400W), phone chargers and electronics (200W), and sump pump (800–1,500W). Higher-capacity models like the MA24-S with surge protection can handle starting loads from central AC units and well pumps. The key is calculating your total load before choosing a generator.
