When you overload a generator, the result can be catastrophic. When you overload a generator, it means that you’re asking it to do more work than it is capable of. If you overload your generator and leave it running for too long, its engine will burn out or catch fire. There are some less serious but still concerning outcomes when you overload your backup generator as well.
When a generator is overloaded, it produces less power than usual or experiences frequent spikes in voltage that can damage sensitive electronics. Read on to learn more about what happens when you overload a generator, how much stress the unit should ideally handle, and how to avoid dangerous overloading conditions in the future.

Finding the Ideal Load Rating
The first step in protecting your generator is determining its ideal load rating. You can find this information in your unit’s owner’s manual or on the manufacturer’s website. You can also talk to a technician to find out the optimal load for a given generator.
Load ratings can vary depending on the generator’s brand, model, and size. For example, a 1,500-watt generator will have a lower load rating than a 7,000-watt generator. Ideally, you’ll want to select a generator that has a load rating that’s higher than the total wattage of all of your critical appliances.
If you have 15 appliances that each uses 1,500 watts, you’ll want a generator with a load rating of at least 20,000 watts. You’ll want a generator with a high load rating because it will be able to handle additional appliances if you need to add to your power usage in the future.
An Important Note About Overloading Your Generator
When we say “overload,” we don’t mean that you need to keep the generator running at full capacity all of the time. You just need to maintain a small amount of extra capacity to account for any fluctuations in your home’s energy usage. If your appliances regularly spike in energy consumption, you’ll need to generate more electricity.
Similarly, if you have an appliance that suddenly starts running nonstop, you’ll need to generate more electricity to accommodate the increased demand. Overloading a generator isn’t something you need to do all the time, but it is something you need to be aware of when generating more electricity than usual.
What Happens When You Overload a Generator?
When you overload a generator, it is working beyond its optimal capacity. For example, if a generator is designed to handle a load of 3,000 watts and you ask it to produce 6,000 watts, it will put a lot of stress on the unit.
When you overload a generator, it puts the unit at risk of burning out or being damaged in other ways. Overloading a generator can cause the engine to overheat and become less efficient.
It can also cause the voltage inside the generator to spike, which can damage sensitive equipment like computers and home appliances.
A generator can experience these problems even when it is still producing electricity. In other words, even if the generator is still running, you can overload it by asking it to do more work than it can handle.

Possible Short-Term Outcomes of Overloading a Generator
If you overload your generator and leave it running for a short period of time, the engine may overheat. It may also experience reduced efficiency, which means that it will produce less electricity than usual. If a short-term overload causes the generator to produce less electricity than it is capable of, it will take longer to power your home or appliances.
In this scenario, the overload may cause your generator to trip or trip your circuit breaker. It’s important to note that as long as you’re generating electricity at all, you’re still protecting your home from blackouts and power outages.
An overloaded generator will simply take longer to power your appliances and protect your home from power outages than a properly loaded generator would.
Long-Term Outcomes of Overloading a Generator
If you overload a generator for too long, it may sustain permanent damage. Even if you unplug the generator and let it cool down, it may be unable to produce as much electricity as it could before the overload.
Overloading a generator for too long can damage the engine, reduce its lifespan, and increase the risk of overheating. It can also cause the voltage inside the generator to spike, which can damage sensitive electronics and appliances.
Overloading a generator for too long can cause permanent damage to the generator. You may need to replace it sooner than you would have otherwise.
What are the causes of the overloading of generators?
Overloading a generator is primarily caused by underestimating your electricity usage and overestimating your generator’s capacity.
At the same time, it’s important to remember that every generator has a load rating and that every generator has its limits. Overloading a generator is not something that happens as a result of poor design or substandard manufacturing.
It is simply a result of asking a machine to do more work than it is designed for. Sure, you may have a big family that uses a lot of electricity, but that doesn’t mean you can just throw more appliances on your generator and expect it to handle the load.
How do you stop a generator from overloading?
If you notice that your generator is starting to overload, you should immediately unplug appliances to reduce the electricity demand. Ideally, you should unplug sensitive electronics like computers and televisions.
You may also want to consider installing a kill switch to reduce the electricity demand on your generator.
A kill switch is an easy-to-use switch that you can flip on and off to control the amount of electricity going to your appliances. A kill switch is helpful because it allows you to reduce the amount of electricity going to your appliances without having to unplug them.
Overloading a generator is a risky and dangerous move that could cause serious damage to both the generator and your home’s appliances. It’s better to be safe than sorry, which means that you should always err on the side of caution when it comes to generating electricity.
If you have a big family, it’s better to have a bigger generator than to invite disaster by overloading a smaller one. If you have an existing generator, make sure that you are not overloading it. You should also be aware of any nearby power outages and use the opportunity to think about purchasing a generator for your home.
