The G12KBN model also has a low oil shut off feature which prevents damage to the fire and reduces the risk of fire.
However, it differs from the Westinghouse model as it comes with a 3-in-1 digital meter that is displayed on the face of the product.

However, similarly to both the Westinghouse and Pulsar models, it has dual fuel capability and is compatible with both gasoline and propane.
Additionally, this device comes with the low oil shutoff feature which is an essential thing to look for if you have safety in mind.
However, this device goes a step further as it comes with an idle control feature.

It also operates for a smaller amount of time than the other devices we’ve looked at, as it will only operate continuously for 10 hours.
However, this device does have features that its competitors do not. One of which is its operating noise.

Best Whole House Generator Buying Guide
Generators are a great investment simply because they have so much potential. They come in a variety of shapes and sizes which are all better suited to different situations.
You can get smaller, portable generators that are perfect for camping trips or family barbeques, and you can also get huge generators that supply enough electricity to power your entire home.
Whole house generators are a trend that is continually growing more popular as an increasing amount of people are choosing to install them in their own homes.
Whether you choose to use the generator as a continual source of power for your home, or simply as a backup in case of emergency, there are all sorts of benefits from a whole house generator.
But with so many different types of generators available it can be very difficult to determine which is the best one for you and your home. There’s no need to stress, however, because we’ve put together this great guide which is packed full of information about whole house generators.
The generators that we’ve looked at above are some of the best on the market, but if you’re still not sure, this buyer’s guide is packed full of all the information you need to buy the whole house generator which is perfect for you.
One very important thing that you need to consider when buying a whole house generator is how you are going to power the device.
This is especially important if you live in an extremely remote area of the country as it can be very difficult to get your hands on the fossil fuels that you need to power the generator.
Most whole house generators will come with three different fuel options for you to choose from, these include natural gasoline or diesel, or propane.
Both gasoline and diesel are the traditional options we would consider when considering powering a device. The majority of vehicles are powered by gasoline or diesel, that’s because both of these materials are extremely easy to obtain.
However, it might become more difficult to obtain these fuels when you consider the amount that you will require to power the whole house generator. All whole house generators will come with an extremely large fuel tank and will require this tank to be full for them to operate properly.
Before you buy a home generator, you must consider the fuel source to ensure you buy one that you will be able to access easily. You should also consider the cost of different fuels.
Obviously, fuel prices fluctuate dramatically from day to day, however, on average, some fuel sources are more expensive than others so you should consider which is a better financial choice for you and your home.
Another extremely important thing that you need to consider is the power that you require from the generator. Different generators will come with different power output abilities which will limit or expand the number of appliances that the generator can supply power to.
In order to power the majority of household appliances, you will need a generator that can produce between 5,000 and 7,000 watts of electricity. However, to operate all of these devices simultaneously, you should buy a generator which exceeds these measurements.
To ensure that you buy a generator that is powerful enough to provide electricity to all of your household, you need to calculate how much electricity all of your household appliances will require.
To do this you need to look at each of your electrical appliances and find the plate which states their starting amps. Once you have found the starting amperage, you also need to identify the volts for the device, you should then multiply these with one another and this will determine the watts that the device needs to run.
You should do this for all of the items in your household that you want to be powered by the generator to determine how powerful a generator you need to buy.
However, when buying a generator you should purchase one that has a peak load which is approximately 25% more powerful than what you need. This is essential to ensure that the generator always has enough power to supply electricity to your whole home.
