Top 5: Most Common Home Generator Mistakes
Mistake #3: Measuring Home Generator Wattage Requirements Incorrectly
Many people who wish to purchase a home generator end up with the wrong size generator because they measure their wattage requirements wrong, usually because they have tried to do it themselves.
The best way to do this is to have a professional electrician do it for you. This ensures that it is done accurately and safely. But if you choose to do the measuring yourself, one important thing to realize is that the startup power requirements of some appliances are much greater than their constant-run requirements. The home generator has to be able to accommodate the power surge that happens when these appliances startup, so pay attention to this important measurement. Appliances that fall under this category are those that have a motor or compressor, like a refrigerator or air conditioner.
Many people don’t realize that a central air conditioning unit requires an enormous amount of power to start their motor and compressor—at least 10-15kW. So if a whole-house AC is on your list of necessary appliances, as it is in many parts of the country, you must factor this in to your wattage requirement calculations for your home generator.
