What To Know

  • Connecting an automatic generator is a task that requires careful planning and execution, and this guide will walk you through the process step by step.
  • It monitors the grid and initiates the transfer of power in the event of an outage.
  • Connect the ATS to the main electrical panel and the generator.

In the face of power outages and unforeseen emergencies, having a reliable backup energy source is crucial. Automatic generators provide peace of mind by seamlessly kicking in to keep your essential appliances and systems running during grid failures. Connecting an automatic generator is a task that requires careful planning and execution, and this guide will walk you through the process step by step.

1. Choosing the Right Generator

Selecting the appropriate generator is paramount. Consider the following factors:

  • Power Output: Determine the total wattage of the appliances and systems you need to power during an outage.
  • Fuel Type: Generators run on gasoline, diesel, natural gas, or propane. Choose a fuel that is readily available in your area.
  • Automatic Transfer Switch (ATS): An ATS automatically switches your home’s power supply to the generator when the grid fails.

2. Installing the ATS

The ATS is the brain that controls the generator’s operation. It monitors the grid and initiates the transfer of power in the event of an outage.

  • Mount the ATS in a dry, well-ventilated area near the generator.
  • Connect the ATS to the main electrical panel and the generator.

3. Connecting the Generator to the ATS

  • Position the generator outside your home, at least 15 feet away from any openings.
  • Securely connect the generator’s electrical output to the ATS using heavy-duty cables.

4. Grounding the Generator

Proper grounding is essential for safety.

  • Drive a ground rod into the earth near the generator.
  • Connect the generator’s grounding terminal to the ground rod with a copper wire.

5. Fueling and Starting the Generator

  • Fill the generator’s fuel tank with the appropriate fuel.
  • Start the generator according to the manufacturer’s instructions.

6. Testing the System

Once the generator is connected, test the system to ensure it is functioning properly:

  • Simulate a power outage by turning off the main breaker.
  • The generator should automatically start and begin supplying power.
  • Restore power by turning the main breaker back on.

7. Maintenance and Safety

Regular maintenance is crucial for the generator’s longevity and performance:

  • Change the oil and filter regularly.
  • Inspect the generator’s components for any damage or corrosion.
  • Keep the generator’s surroundings clear of debris and flammable materials.

What People Want to Know

1. What are the benefits of having an automatic generator?

  • Peace of mind during power outages
  • Protection for sensitive electronics and appliances
  • Continuity of essential systems (e.g., refrigeration, medical equipment)

2. How much does it cost to connect an automatic generator?

The cost varies depending on the size and type of generator, ATS, and installation labor. Expect to pay between $2,000 and $10,000.

3. Can I connect an automatic generator to my home myself?

While it is technically possible, it is highly recommended to hire a licensed electrician for professional installation to ensure safety and proper operation.
