What is a Generac Generator?

Generac generators are a leading choice for reliable backup power during emergencies, particularly for homeowners. They come in a variety of models, including portable and permanent setups made to be installed outside the home. They’re designed to provide power for critical appliances and systems during outages.


Generators are especially helpful during extreme weather events, prolonged blackouts, and for areas prone to grid instability. A Generac generator supplies uninterrupted power to keep your home safe and comfortable as a back-up energy source. If you’re wondering about the best place to buy a home standby Generac generator, certified Generac home standby generator dealers like In Charge Electric offer expert guidance and reliable service, making them the go-to choice.

What Are the Safety Precautions for a Generator?

Using a generator improperly can pose serious risks, including carbon monoxide poisoning. To stay safe, keep these precautions in mind:

Should You Follow Safety Measures Using a Home Standby Generator?

When you opt for a home standby generator, you’ll have less hands-on operation—a big perk many homeowners enjoy. When you have your home standby generator installed by a trained Generac dealer and technician, we’ll make sure your generator is properly set up, so you don’t have to worry about a thing. Then, the self-sustaining machine will be there to automatically get to work when your power goes out. 


How to Use a Generator Safely: 6 Key Steps

1. Follow the Generator’s Manual

Before operating your Generac generator, you should learn how to use a generator. Thoroughly read the manufacturer’s instructions. The manual contains essential safety guidelines, maintenance tips, and operational details tailored to your specific model.

2. Find the Optimal Location for Your Generator

Position the generator in a well-ventilated outdoor area, far from windows, doors, or vents. Avoid placing it near flammable materials or in areas where water might pool. You’ll also want to keep your home standby generator at least 5 feet away from your home. In contrast, portable generators are usually fire-safe, which means they can be set up closer to your home as long as they are at least 5 feet away from windows and doors. 

3. Monitor the Fuel Levels and Fuel Type

Using a portable generator? Double check your owner’s manual to learn more about which fuel types are supported, like propane, gasoline, diesel, or natural gas. Some portable generators can even support multiple types of fuel.

Using a home standby generator? These can run on propane and natural gas, but can’t be switched by you. Instead, this will have to be chosen at installation and can only be changed by a licensed technician. 

Using propane? Ask your sales rep about a Propane Tank Utility Monitor, which helps monitor the remaining fuel in your tank and can even be linked to an app on your phone. 

4. Follow Proper Start-Up and Shut-Down Steps

Always start and stop your portable generator according to the manufacturer’s instructions. Home standby generators will always automatically cycle through, which means you don’t have to stress about start-up and shut-down.

Ready to turn on your portable generator? Make sure you disconnect all devices and move the switch to the “on” position. Then, head to the main circuit breaker and flip it on.

When it comes time to turn off your portable generator, ensure you’ve turned off all the appliances connected to it to help you avoid any damage. 

5. Do Not Overload the Generator’s Capacity

When it comes to a portable generator, you do have to worry about overloading, so it’s important to know your generator’s power limits and prioritize essential appliances. Overloading can cause malfunctions or even permanent damage to the generator, making this an important part of learning how to use a generator. 

6. Monitor Generator for Warning Signs

Watch for unusual noises, vibrations, or warning lights while the generator is running. Schedule regular maintenance with a Generac Service Technician once per year to keep your generator in top condition.


4 Common Mistakes to Avoid When Using a Generac Generator

1. Putting the Generator on an Uneven Surface 

It’s important to make sure that your portable generator cannot tip, as this can lead to overheating, fuel spillage, and even a fire. A portable generator that’s unstable can also pose additional risks, like performance issues and internal damage. 

To keep your portable generator safely up and running, you’ll want to place it on a flat and dry surface. This can include compacted gravel, a concrete pad, or just a flat section of your driveway. When you keep it level, you ensure proper oil and fuel distribution, helping lower your risk of mechanical issues—and keeping your power going.

2. Using the Wrong Cords

When learning how to use a generator that’s portable, it is important to note that not all extension cords are suitable for generator use. Standard household cords are typically not built to handle the high current and power output of a generator, which can lead to overheating, fire hazards, or even equipment failure. Instead, use heavy-duty, outdoor-rated cords designed for generators. These cords are often labeled with their amperage capacity and include weatherproofing features. Additionally, choose cords of the shortest possible length to minimize voltage drop, which can reduce the efficiency of connected appliances.

3. Adding Fuel While the Generator Is Running

Refueling a generator while it’s running or still hot is one of the most dangerous mistakes you can make. Gasoline vapors are highly flammable, and any contact with the generator’s heat or sparks can result in a fire or explosion. To refuel safely, always turn off the generator and allow it to cool completely. Use a funnel to avoid spills and store fuel in an approved, tightly sealed container. Remember to refuel only in a well-ventilated outdoor area, away from open flames or other ignition sources.

4. Not Weather-Proofing Your Generator

While many Generac generators are designed for outdoor use, they are not entirely weatherproof. Exposure to rain, snow, or excessive moisture can lead to electrical malfunctions .or corrosion, reducing the generator’s lifespan. Protect your generator by placing it under a canopy or purchasing a weatherproof cover specifically designed for your model. 

Keep in mind that a home standby generator is a stress-free backup power option that comes without many of the safety risks associated with portable generators. And when you trust an In Charge Electric certified generator maintenance technician, we’re on call, so you can rest easy.
