What Will A 7000 Watt Generator Run?

7000 watt generatorWondering what will a 7000 watt generator run? The short answer is, that a generator of 7,000 watts will be able to run almost anything in times of blackouts or power outages. Such generators have one engine, typically use gas, sometimes propane or diesel. You will also be able to find a few outlets and usually feature circuit breakers. The circuit breakers are there to protect the engine from damaging due to overload. Such generators will also be able to run several appliances at the same time. However, don’t expect it to do so permanently.

Power Requirements

Before getting to know what appliances you can run, you also need to know the power requirements of them. Most appliances have that information on their power cords and you will find them in watts. Other times, you will find the specifications in amps as well. If you want to convert from amps to watts, you need to multiply amps by the voltage on which the appliance runs. It should be either 120 or 240 volts.

The ones that run on 240 volts, like water heaters, naturally require more power. So, keep in mind, that sometimes such appliances are so power hungry that they will demand all the power output from the generator. However, that shouldn’t be a problem if you are using a 7,000 watt generator as it already has a lot of power.

Buying a 7,000 watt generator is great for houses with 3,000 square feet of area. In other words, it is ideal for big houses as it can run a lot of different items.

The Start-Up Power

Appliances like refrigerators usually need more power to start up. Those appliances cycle on and off. That power can sometimes be three times larger than its running power. One such example is that if a fridge needs 600 watts to draw while it’s running may need 2,200 watts to even start. Those notes should be kept in mind because it is very easy to forget. Also, if you don’t remember, the circuit breakers will start tripping.

If you know what appliances you want to run, you need to add up the watts. It’s important to remember you need to add up the start-up ones. Once you add it up and if it results in less than 7,000 watts, you don’t need to worry about overloading a generator. However, if it exceeds 7,000 watts, you will still be able to run all the appliances. But, you can only do that if the ones that you are using at the moment are less than 7,000 watts. Also, be sure to add 10% of uncertainty factor when you add up the power requirements.

Sample Application

There are a few things to be taken into consideration if you use the 7,000 watt generator in winter. One thing that is recommended is operating a furnace. The size of the fan motor depends on how many watts it needs to cycle on. In estimate, it will require around 2,200 watts to cycle on. If you decide to power a fridge (which requires the 2,200 watts), you will also have leftover power in the generator.

With that leftover power, you will be able to run a TV, radio, a few lights, and some kitchen appliances like a blender. Instead of the refrigerator, you can even use a washing machine, electric range or even a microwave. It could happen that the generator won’t be able to run those at the same time. However, 7,000 watts is a lot of power so it shouldn’t be that uncommon for them to run at the same time. Just to be sure, it is recommended to calculate the wattage of those appliances.

With a 7,000 watt generator, you will be able to run many things. Some of those things include house lights, an air conditioner as well as a refrigerator. In other words, a generator with 7,000 watts can keep your house powered and secured without many problems. It can run both AC and a refrigerator at the same time. In this way, you won’t be feeling hot and your food in a fridge won’t spoil.

On the other hand, 7,000 watts is more than enough for almost any household. That is because in cases of blackouts, you will only need a few appliances to run. It is not very likely that you will need many items to run at the same time. With this type of a generator, you can even run several refrigerators along with a few light bulbs with a few fans. All of this consumed only 3,300 watts. So you will definitely have a lot of spare power for further consumption.

However, keep in mind that surge power is always higher than running power. So, surge power can easily reach 5,800 watts if all of them are turned on. You shouldn’t expect the generator to run a large central air conditioner. However you can run small electronic devices like TV, coffee maker and a fridge at the same time.

Keep in mind that if appliances that are already plugged in have a big wattage, you might not be able to run a large appliance. Well, you can’t if you don’t disconnect the other appliances. For a much better understanding, here is an example of what the 7,000 watt generator can run: a water heater of 40 gallons, two hot plates, two electric stoves, three window air conditioners. Others are: three or more microwaves or power tools, five refrigerators, six laptops, and even two air compressors. All of that can be on at the same time.


A 7,000 watt generator will be able to run the most important appliances you have in your home. They are the most basic electronic devices like refrigerator, AC, lights and more important kitchen appliances like microwave. Hopefully, you know now what a 7,000 watt generator can run. And, hopefully, this article has been informative enough.

  1. I have a7000 watts generator I have lights refrigerator and TV dishwasher and microwave on it I was told that is all it can carry

  2. 7000 watt 10k watt max
    runs 2500sq foot 4 bedroom house
    I have LED low watt bulbs, but the generator runs AIR CONDITIONING, all lights TV ,fridge.

    only time it would trip is maybe microwave,toaster even ans fridge turning on at same time
