If your home has 200 amp electrical service, it’s natural to wonder whether your generator needs to match that number. It doesn’t—but it does need to handle the actual load you’ll put on it. That distinction matters more than the panel rating when it comes to finding the right size.
We use your home’s real power usage to guide that decision, not assumptions about what a 200 amp service implies.
Hear the explanation directly from our team:
Does My Generator Need To Match My Electrical Panel?
No. The generator doesn’t have to match your home’s electrical service rating. For most homes with 200 amp service, we’ll often install a generator around 100 amps instead. What matters is whether it can reliably run the equipment you need during an outage—not whether it mirrors the panel.
How Do You Determine The Right Generator Size?
We size a generator one of two ways: a load calculation or a smart meter review. A load calculation adds up the electrical demand of your home’s equipment to project what the generator needs to handle. If your utility uses a smart meter, we can look back at your actual usage history and pinpoint your home’s highest recorded draw—a real-world reference point that’s more accurate than working off the panel rating alone. Either way, the goal is a generator sized to what your home has actually demanded, not a worst-case estimate.
