What Are the Top Mistakes Homeowners Make When Using a Portable Generator During a Power Outage?

Portable generators can be a lifesaver during a power outage, but when used incorrectly, they can quickly become dangerous or ineffective. One of the most common mistakes homeowners make is running a generator too close to the house, garage, or open windows. Generators produce carbon monoxide, a colorless, odorless gas that can be deadly if it builds up indoors. A generator should always be operated outdoors and far away from any openings to the home.

Another frequent error is attempting to “backfeed” power into the home by plugging the generator directly into a wall outlet. While this may seem like a quick solution, it is extremely dangerous and illegal in many areas. Backfeeding can energize utility lines, putting linemen and neighbors at serious risk and potentially damaging your home’s electrical system. The proper way to connect a generator is through a professionally installed transfer switch or interlock system.

Overloading the generator is also a common problem. Many homeowners underestimate how much power their appliances and systems require, which can cause the generator to trip, overheat, or fail prematurely. High-demand items like furnaces, sump pumps, refrigerators, and well pumps should be prioritized, and non-essential devices should remain unplugged.

Improper fuel handling and storage is another mistake that can lead to serious safety issues. Refueling a hot generator can cause fires, and storing fuel improperly increases the risk of leaks or explosions. Fuel should always be stored in approved containers and refilled only after the generator has cooled completely.

Finally, many homeowners fail to maintain their generator or test it before an outage occurs. Old fuel, clogged filters, or dead batteries can leave you without power when you need it most. Routine maintenance and periodic test runs ensure your generator is ready to perform safely and reliably during an emergency.

Using a portable generator the right way is about more than convenience—it’s about safety. Planning ahead, understanding proper connections, and working with a licensed electrician when needed can help protect your home, your family, and anyone working on the power lines during an outage.
