Generators serve as a reliable source of power during outages, providing comfort and continuity in your everyday life. Understanding how they function can inform your purchasing decisions as well as aid in the maintenance and effective use of the system.
Whole-home, or standby generators, are designed to automatically supply power to your home when there’s an unexpected outage. They’re permanently installed outside your home and wired into the electrical system through an automatic transfer switch.
The functioning of a whole-home generator can be broken down into four key steps:
Step 1: Power Outage Detection: When the generator senses a power outage, it sends a signal to the automatic transfer switch.
Step 2: Activation of Transfer Switch: In response to this signal, the automatic transfer switch disconnects your house from the utility line, effectively isolating your electrical system.
Step 3: Generator Startup: The generator starts up automatically upon receipt of signal from the transfer switch. This usually happens within seconds of a power outage.
Step 4: Power Transfer: Once operational, the generator supplies power to your home’s electrical system through the automatic transfer switch. Your home is now powered by the generator until utility power is restored.
Notably, whole-home generators operate on natural gas or liquid propane (LP) fuel and hence do not require manual refueling like portable generators. They are capable of powering all essential appliances including lights, heating and cooling systems, refrigerators, sump pumps or even an entire house depending upon their capacity.
Upon restoration of utility power, whole-home generators go through three final steps:
Step 5: Deactivation Signal: The automatic transfer switch detects when utility power has been restored and signals this to the generator control panel.
Step 6: Transition Back to Utility Power: The control panel commands the transfer switch to reconnect your house back to the utility line, and your home is now back on grid power.
Step 7: Cool Down and Standby: The generator runs for a few more minutes to cool down before shutting off and going into standby mode, ready for the next power outage.
Understanding your generator’s functioning cycle not only demystifies how it operates but also helps you maintain its efficiency. Regular maintenance like changing the oil, replacing spark plugs, checking battery status and ensuring proper coolant levels can extend your generator’s life significantly.
Having a home generator is an effective way of ensuring that you have continuous power even during outages. However, it’s not always necessary or cost-efficient to back up every single circuit in your home. Identifying and determining the critical circuits for optimal backup power is a crucial step in maximizing the efficiency of your generator while minimizing unnecessary energy consumption.
Critical circuits are essentially the electrical lines in your home that power up the most essential appliances or systems—those that need to keep running even during a power outage. This may include, but is not limited to, refrigerators and freezers (for food preservation), heating and cooling systems, lighting for important areas (like kitchens, bathrooms, and hallways), security systems, medical equipment (if any), internet modems/routers (for communication purposes), and possibly a few outlets for charging phones or other devices.
Los Angeles, CA Generator: How to Identify Critical Circuits
Identifying critical circuits involves understanding your household needs when there’s no electricity from the grid. Consider which appliances or systems you can’t do without during an outage. Here are steps you can take:
- List down your essential appliances/systems: Make a list of all the devices/appliances in your home that you consider essential.
- Check their individual power ratings: Check each appliance’s power rating usually indicated on its nameplate or in its manual.
- Calculate total wattage: Add up all these individual ratings to get an approximate total wattage that your generator needs to provide.
To help categorize the critical circuits in your home, here’s a sample table:
Appliance/System | Power Rating | Essential During Outage |
Refrigerator | 600W | Yes |
HVAC System | 3500W | Yes |
Security System | 500W | Yes |
Internet Router | 100W | Yes |
Home Theater | 2000W | No |
Finding the Perfect Home Generator in Los Angeles, CA
Once you have identified the critical circuits, the next step is determining how to allocate backup power efficiently. The total power requirement of your essential appliances should ideally be less than the output capacity of your generator. This will ensure optimal operation without overloading the generator.
If the total power requirement exceeds the generator’s capacity, you may need to prioritize even further or consider getting a larger generator. Keep in mind that some appliances like refrigerators, air conditioners, and pumps require more power to start (surge wattage) than they do to run (running wattage). Your generator should be able to handle these surge wattages as well.
By identifying and determining critical circuits for optimal backup power, you can make sure that your home generator serves its purpose effectively—keeping your home functioning as normally as possible during a power outage while maximizing fuel efficiency and minimizing wear on the generator.
Before you embark on the journey of installing a home generator, it is necessary to take into account certain key aspects that can greatly affect the success and efficiency of your installation. Some of these key aspects include the generator’s location, fuel source, and code compliance.

The location of your home generator is critical for its operation and maintenance. Here are some factors you should consider while deciding the right spot for your generator:
- Space: Ensure that there is enough space around the generator to allow for maintenance activities. The recommended clearance is at least 5 feet on all sides.
- Distance from house: The generator should not be too close to your home as it could pose a fire risk or cause noise disturbances.
- Protection from elements: The generator should be placed in a way that it’s protected from harsh weather conditions but still have access to fresh air for cooling.
Fuel source
The type of fuel your generator uses will also play a big role in its operation:
- Natural Gas: This is a common choice due to its availability in many homes. Generators running on natural gas don’t require regular refilling, making them convenient.
- Propane: Propane generators offer long shelf life and are an excellent choice if natural gas isn’t readily available. However, they require regular refilling.
- Diesel: Diesel generators are reliable and efficient but require regular maintenance.
Choosing a fuel source depends largely on what’s readily available in your area and the application of the generator.
Code Compliance
Code compliance ensures safety and efficiency in installation and usage of home generators:
- Local Building Codes: These codes dictate how electrical systems should be installed in homes. They ensure safety standards are met during installation to minimize risks associated with electricity.
- National Electrical Code (NEC): This code sets the foundation for electrical safety in residential, commercial, and industrial settings. It provides guidelines on how to install and maintain electrical appliances safely.
Before installing a generator, ensure you understand these codes or hire a professional who does. Failure to adhere to these codes could lead to legal issues, fines, and even risk of fires or electric shocks.
Making informed decisions about the location, fuel source and code compliance before installing your home generator not only ensures efficient operation but also increases the life span of your generator while ensuring the safety of your home. Accordingly, they are significant aspects you must consider beforehand.
