How Do Generators For Homes Work?
As a homeowner, the idea of having a generator for my house is something that has crossed my mind, especially during power outages. Generators can provide a reliable source of backup power, allowing you to keep your lights, appliances, and other essential systems running even when the power goes out. But how exactly do generators work for a house?
In this article, I’ll go over the different types of generators that can be used for a house, how they generate power, and what to keep in mind when choosing a generator for your home.

Types of Generators for a House
There are two main types of generators that can be used for a house: portable generators and standby generators.
- Portable generators: As the name suggests, portable generators are small and can be easily moved around. They can be powered by gas, propane, or diesel and are often used as a temporary solution during power outages. They can be used to power small appliances and tools, but they are not powerful enough to run the whole house.
- Standby generators: Standby generators are larger and more powerful than portable generators. They are designed to be permanently installed outside of your home and are connected to your electrical system. They are powered by gas or propane, and they automatically turn on in the event of a power outage, providing power to your whole house.
How Generators Generate Power
The process of generating power by a generator is known as electromagnetic induction. In a generator, there is a device called an alternator, which converts mechanical energy into electrical energy. The alternator has a rotor and a stator. The rotor is connected to an engine, which spins the rotor. This movement generates a magnetic field that passes through the stator. The stator is made up of coils of wire, which create an electrical current when the magnetic field passes through them. This electrical current is what powers your house.
What to Keep in Mind When Choosing a Generator for Your House
When choosing a generator for your house, there are a few things to keep in mind:
- Power needs: The first thing to consider is how much power you will need. The size of your house, the number of appliances and lights you want to power, and the type of HVAC system you have will all affect how much power you need. Be sure to choose a generator that can provide enough power for your needs.
- Fuel source: Generators can be powered by gas, propane, or diesel. Each fuel source has its own advantages and disadvantages. Gas generators are the most common and are generally the easiest to find, but they can be affected by gas shortages during power outages. Propane generators are a good option if you already have a propane tank, but they may be more expensive to operate. Diesel generators are the most efficient but can be more expensive upfront.
- Noise level: Generators can be quite loud, especially portable generators. If you plan on using your generator during the night or in a residential area, be sure to choose a generator with a low noise level.
- Safety features: Safety is important when it comes to generators. Be sure to choose a generator with safety features such as low oil shut-off, which automatically turns off the generator if the oil level gets too low.
- Maintenance: Generators require regular maintenance to ensure they are running properly and safely. Be sure to choose a generator that is easy to maintain and has easy access for servicing.
Connecting the Generator to the House
When it comes to connecting a generator to a house, there are a few different options. The method used will depend on the type of generator and the specific electrical system of the house.
- Portable generators can be connected to a house using a heavy-duty extension cord to connect the generator to specific appliances or circuits. Another option is to use a transfer switch which is installed between the generator and the electrical panel and allows you to safely connect the generator.
- Standby generators are connected to the house’s electrical system through a transfer switch which allows the generator to automatically turn on in the event of a power outage and provide power to the whole house. Depending on the type of generator and the specific electrical system of the house, a licensed electrician may be required to properly connect the generator to the house.
