How to Size a Standby Generator and Choose the Right Transfer Switch

When spring storm season rolls across the plains, severe weather can knock out grid power in the blink of an eye. For homeowners in the Tulsa area, sudden power outages are more than just an inconvenience; they can disrupt your comfort, spoil food, and leave essential medical devices without power. That is why investing in a reliable backup power solution has become increasingly popular. But choosing the right equipment involves more than simply picking a unit off a shelf. You need to know how to size a standby generator correctly and understand how an automatic transfer switch keeps your home safe and seamless during an outage. In this guide, Durant Electric, LLC breaks down exactly what you need to know to prepare your home for the next severe weather event.

Determining the Right Generator Size for Your Home

One of the most common questions we receive is about how to size a standby generator. Sizing whole home backup power systems requires a careful calculation of your household's electrical load. If you choose a generator that is too small, you risk overloading the system and damaging your appliances. If you buy one that is too large, you are spending money on capacity you will never use.

To start, we look at your home's essential circuits. Do you just want to keep the lights on, run the refrigerator, and power a few outlets? Or do you want your air conditioning, electric water heater, and home office running at full capacity? We perform detailed voltage tests and load calculations to give you an accurate recommendation. Homeowners often ask us to compare options, such as Generac vs Kohler generators, to find the best fit for their specific power demands and budget. Because sizing can get complicated, having a licensed electrician evaluate your panel ensures your backup system will perform flawlessly when you need it most.

The Importance of the Automatic Transfer Switch

A standby generator is only as good as the system that connects it to your home. That is where the automatic transfer switch comes in. When reading through any automatic transfer switch installation guide, you will learn that this device acts as the brain of your backup power system. The moment it detects a drop in utility power, it safely disconnects your home from the grid and signals the generator to start.

This immediate transition is vital for two reasons. First, it provides a seamless flow of electricity to your home without you ever having to brave the storm to flip a switch manually. Second, it prevents "backfeeding"—a highly dangerous situation where your generator sends electricity back into the utility lines, putting line workers at serious risk. Because of the safety implications and the strict electrical codes involved, our installation and inspection process ensures that every switch we wire meets the highest standards for safety and reliability.
