What is an electric generator and how does it work?

Before starting, it is important to know what an electric generator is and how it works. An electrical generator is a device that converts mechanical energy into electrical energy. The generator has an engine that runs on gasoline or diesel, and once it is turned on, it spins a rotor that is surrounded by a magnetic field, producing electrical energy.

What types of electric generators are there?

There are two types of electric generators:

portable generators

Portable generators are compact, transportable devices that generate electricity by burning fuels such as gasoline, diesel, or propane. They are designed to supply power in areas without access to a power grid, being useful in remote locations, camping or during emergencies. 

These generators have an internal combustion engine that drives an alternator to generate electrical current, and often have standard outlets to connect devices. It is important to use them safely, follow the manufacturer's instructions, and perform proper maintenance.

stationary generators

Stationary generators are stationary devices that provide backup electrical power in the event of interruptions to the main electrical grid. They are permanently connected to the building via an Automatic Transfer Switch (ATS) and are used in homes, businesses and industrial facilities to ensure a continuous power supply during power outages. They require professional installation and regular maintenance to ensure reliable operation.

How to Connect an Electric Generator to the House

Portable generators are a great option for supplying power in places where there is no access to a power grid, such as in remote areas or during emergencies. Here are some key things to know about portable generators:

  1. Power generation capacity: Portable generators come in different power generation capacities, which are measured in watts (W). It's important to select a generator that has enough capacity to power the devices and appliances you want to use. Consider the required wattage of the appliances and devices you plan to use simultaneously to determine the proper capacity of the generator.
  2. Fuel: Portable generators typically run on gasoline, diesel, or propane. You should be aware of the type of fuel the generator uses and make sure you have enough fuel safely stored. It is also important to follow safety guidelines when handling and storing fuel.
  3. Security: Portable generators should be used outdoors or in well-ventilated areas due to the emissions of toxic gases, such as carbon monoxide (CO). You should never use a generator indoors or indoors, as it can cause CO poisoning. Be sure to locate the generator a safe distance from windows, doors, and areas where CO can enter the home.
  4. Wiring and connections: Portable generators often have standard outlets, such as power outlets or plugs, to which devices can be connected via cables. Be sure to use quality cords and extension cords that are suitable to handle the power load and prevent overloading. It is also important to follow the manufacturer's instructions on how to make the connections correctly.
  5. Maintenance: Portable generators require regular maintenance to ensure proper operation. This includes checking and changing the oil, cleaning the air filters, checking the spark plugs, and keeping the fuel system clean. Consult the generator manual for specific maintenance instructions.
  6. Proper use: Carefully read and follow the manufacturer's instructions for safely operating the generator. Make sure you understand how to start, shut down, and operate the generator correctly. Avoid overloading the generator and do not connect devices that exceed their maximum power output capacity.

Remember that while portable generators are useful, it is important to use them responsibly and safely. Always follow the manufacturer's recommendations and consider hiring a qualified electrician if you need to do a more complex or permanent installation.

How to Disconnect the Electric Generator?

Disconnecting an electric generator safely is essential to avoid possible risks and damages. Here are the steps to disconnect an electrical generator:

  1. Turn off devices: Before unplugging the generator, make sure you turn off all devices and appliances connected to it. This will prevent any overload or disconnection issues.
  2. Stop the fuel supply: If the generator runs on gasoline, diesel, or propane, be sure to close the fuel supply valve to stop the flow to the generator. This will help prevent leaks and fire hazards.
  3. Turn off the generator: Locate the kill switch or on/off key on the generator and turn it off. Be sure to follow the manufacturer's specific instructions for shutting down the generator properly.
  4. Disconnect the power cables: If there are power cables connected to the generator, safely disconnect them. You may need to unplug them from outlets or unscrew them, depending on the type of connection used.
  5. Store the generator properly: If you do not plan to use the generator in the near future, it is important to store it safely. Be sure to drain any remaining fuel following the manufacturer's instructions, and store the generator in a sheltered, dry location.

Remember that these are general steps and the specific instructions may vary depending on the model and manufacturer of the generator. Always consult the owner's manual or seek professional advice if you have questions about how to safely disconnect an electrical generator.

Safety tips for connecting an electric generator to your home

Connecting an electric generator to your home carries certain risks, so it's important to follow some safety precautions to ensure proper installation. Here are some safety tips for connecting an electrical generator to your home:

  1. Suitable location: Place the generator in a well-ventilated, outdoor area, away from windows, doors, and entry areas of the home. Never use it in closed spaces, such as garages, basements or inside the house, as it can generate dangerous gases, such as carbon monoxide (CO).
  2. Ground connection: Be sure to properly connect the generator to a ground source. Use proper cables and connections to ensure a safe connection and reduce the risk of electric shock.
  3. Safe cables and connections: Use quality extension cords and proper connectors to connect devices and appliances to the generator. Avoid overloading the cables and make sure they are in good condition with no visible damage.
  4. Proper maintenance: Perform regular maintenance on the generator according to the manufacturer's instructions. This includes checking the oil level, cleaning the air filters, and keeping the fuel system in good shape. A well-maintained generator is safer and more efficient.

Always remember to read and follow the manufacturer's instructions for your specific generator and be aware of the recommended safety precautions. Safety should always be the priority when connecting an electric generator to your home.
