Frequently Asked Questions

How Can I Connect a 10000W Generator to My Home?

The major benefit of using a portable generator of this size is, it’s the capability to handle the majority of your household electrical requirements.

You’ll have to make use of a transfer switch to connect a generator to your house safely. This helps you in safely switching between generator & utility power, preventing you or your generator from any harm.

We’ve several different transfer switch kits, which contain all you require to ensure a safe connection, as well as operation of your portable generator at home. We’d advise that you use the service of a professional electrician, who is familiar with this kind of installation to get it done for you.

While the kits offer detailed instructions and contain every necessary cabling and breaker, you may not find it a simple DIY task, and the kits need to be certified as adhering to local regulations.

The majority of transfer switch kits for your portable generator come with a large 50A plug. This allows you to connect your generator to your home easily. It’s simply as fast, easy, and safe to disconnect the machine to use it elsewhere or for storage.

This looks all very convenient and easy, but we’ve certain limitations to making use of a 10000-Watt generator for powering your house during a blackout.

Based on the size of the house and the kind of electrical appliances you’re planning to use, a 10000-Watt generator will usually require that you sacrifice certain circuits in the house in a bid to allow for the maximum wattage, which the machine supplies. This implies choosing only certain circuits to run off the generator power.

How Can I Take Good Care of My Generator?

You want to ensure that you don’t put too much load on your portable generator. It won’t harm the generator or expose you to any risk, but putting too much load on the generator circuit will make the circuit breaker trip. And this becomes pesky if it happens often.

Thus, it’s recommended that you calculate your expected consumption for ensuring your needs stay within the capabilities of your generator set. This process isn’t actually an exact science as you can’t know for certain what appliances you’ll be making use of and when.

We’ve a lot of appliances, which start automatically such as air conditioners and refrigerators, with a thermostat used for controlling them. This implies you’ve no full control over your power consumption.

All things considered, limiting all your equipment to within the output of the generator isn’t so important. By applying a certain amount of common sense, you can ascertain the possibility of all your appliances being made use of at once.

If you’re ready to take note of these limitations when making use of your generator, consider making provision for a lot more than the amount of load the machine can cater to at once.

You only need to bear in mind that you can’t run all your appliances at once, and always note that certain appliances can switch on at any time.

How Can I Calculate the Load to Put on My Generator?

To prevent overloading your generator, you need to start by considering appliances that are essential and those that would be nice (if it’s feasible). We advise that you make use of gas for your cooking needs when you’re on generator power since electric stoves consume huge amounts of power.

Apart from that, it’s a bad idea to connect a water heater when running on a generator. Based on your hot water storage capacity, the kind of heat insulation you’re making use of & your consumption level of hot water, it’s possible to ensure your hot water supply stays adequately warm for up to 2 or 3 days.

If you live in a very cold climate, a central heating furnace could be essential. But do note that this can make use of 4000W or more, so you may consider making use of a space heater during blackouts. AC units aren’t too bad so long it’s just a room air conditioner and not a centralized unit that comes with a large compressor.

Here’s a compilation of a common household power consumption setup for a generator circuit:

  • Mid-sized refrigerator 850W (1800W peak)
  • Air conditioner 1200W (2500W peak)
  • Deep freeze 850W (1800W peak)
  • Microwave oven 800W (1750W peak)
  • Sump pump 650W (1300W peak)
  • Plasma TV 120W
  • Surround sound system 40W
  • Desktop computer with monitor 350W
  • 10 X 20W CFL lights 200W
  • Electric kettle 1200W
  • Space heater 1000W

— Maximum load including starting watts: 12060W

— Maximum running watt requirement: 7260W

How Are Running Watts Different from Starting Watts?

Going through the list above, you can see the maximum running watts are less than the running power rating of the CAT RP12000E reviewed above, with enough wattage to spare. Also, the peak starting watts are less than what the model supplies. With such a model, you’ll have some freedom to run as many appliances as possible. But consider applying some logic here so as not to overload the machine.

Also, there are some small items, not on this list such as phone chargers, etc. It isn’t crucial to add items like these as they only draw a few watts, so taking care of the big appliances is the main thing here.

But for the other generator models above, the scenario is a bit different. While the peak wattage in the list above could lead you to believe a 10000W generator won’t be okay, please consider applying some simple logic. You may not really use all these appliances at the same time.

If you’re making use of the space heater, you won’t be using the AC. Then, you also need to bear in mind that it’s highly unlikely all the high-current startup items of equipment will start at exactly the same time.

Also, you’ve some control over the situation. For instance, if you’ll be using the microwave, it won’t require too much effort to put the AC unit off for some time or ensure your electric kettle isn’t on at this time.

If you want to make use of your iron (±1000W) or a hairdryer, which draws a similar wattage, the same tip also applies.

You only need to ensure you’re not running too many equipment at once.

When it’s really necessary, a 10000W generator will handle all these home appliances with a slight compromise on your end. If you eventually put too much load on the generator, this will be seldom, and it’s not likely you’ll be running back and forth all the time to get the breaker reset.

It won’t be long for you to become accustomed to this — a couple of trips to the breaker box will enable you to soon learn what’s possible with the generator model you’re making use of.

When Do 10,000 Watts Become Necessary?

We’re seeing more and more persons suffer from blackouts with areas of greater weather volatility across the world. Tsunamis, hurricanes, tornadoes, and similar natural disasters often bring about power outages & blackouts for millions of individuals annually and typically for extended periods.

A 10000W generator can be of help in powering and stabilizing homes for longer stretches of time compared with home generators with lower watt. Such generators can keep your home appliances, such as refrigerators, window units, fans, and heaters working to ensure you and your family stay safe until power gets restored.

How Can a Large Power Generator Help out on My Job Sites?

A large generator can be a priceless tool when you’re working on a job site, where there’s no power setup. With a 10000-watt generator, you can easily power or even charge the largest among your appliances. If you work out of a mobile office building at your job site, with these generators, you can easily power an air conditioner unit to keep you cool on hot summer days.

How Much Gas Does a 10000W Generator Consume?

Inverter generators come with much more fuel efficiency compared with traditional generators. Though traditional generators can go through up to 18–20 gal. of gasoline in 1 day, inverter-type generators make use of just a fraction of that. As a matter of fact, inverter generators can work on 8 gals. of gasoline within that time frame of a day.


Though a 10000-watt portable generator may not be a part of everyone’s wish list, when the need arises, you’ll wonder how you could do without buying one. These kind of generators have a variety of use cases and have different sizes and power ratings. To recap, these are the top generators we’ve discussed.
