Backup Generator

Need a backup generator installed for a house or business?

A backup generator for a home or business is designed to provide electrical power during a power outage or when the main power supply is unavailable because of weather or other reasons. These generators are typically powered by fuels such as gasoline, diesel, or natural gas and are designed to automatically turn on and supply power to critical circuits or the entire building..

Here’s a general overview of how a backup generator works:

Power Monitoring

Modern backup generators often include power monitoring capabilities. These systems constantly monitor the voltage and frequency of the utility power supply. If the power supply becomes unstable or drops below a certain threshold, the generator is triggered to start automatically.

Transfer Switch/Automatic Start-Up

Once the generator receives the signal, it starts up and begins generating electricity. When the transfer switch detects a loss of utility power or a voltage/frequency deviation, it sends a signal to the backup generator to start. The generator’s engine then cranks and starts running.

A transfer switch is a crucial component that connects the backup generator to the electrical system of the house or business. It ensures that the generator is safely and automatically connected to the building’s electrical system when the main power supply fails. This switch prevents backfeeding, where power flows back into the utility lines, which could endanger utility workers.

Once the main power supply is restored or stabilizes within normal parameters, the transfer switch senses this change and signals the generator to shut down. It then reconnects the building to the utility power grid.

Generator Unit

The backup generator consists of an engine and an alternator. The engine, fueled by the chosen energy source, is responsible for driving the alternator. As the generator’s engine runs, it rotates the alternator, which generates electrical power. This power is routed through the transfer switch and distributed to the essential circuits or the entire building, depending on the setup.

Fuel Supply

The generator requires a constant supply of fuel to operate. Gasoline or diesel generators usually have an integrated fuel tank, while natural gas or propane generators are connected to an external fuel source such as a natural gas line or propane tank.

Backup generators can provide power for a short period of time or for extended periods of time depending on the size of the generator and the fuel supply. They are essential for businesses that require uninterrupted power supply, such as hospitals, data centers, and emergency response services, as well as for households that need to keep their critical appliances running during a power outage.

It’s important to note that backup generators require regular maintenance and periodic testing to ensure they are in proper working condition when needed. It’s also crucial to follow safety guidelines and local regulations during installation, operation, and fuel storage.

A backup generator is a complex piece of machinery that should be installed by an experienced and qualified electrician.
