Common Household Electrical Appliances and Their Wattage Requirements

Understanding your power needs is essential when connecting a portable generator to your house. Here's a chart of common household electrical appliances and their starting and running watts to help you choose the right generator capacity.

Calculating Your Generator Needs

  1. List the appliances you want to power during an outage.
  2. Note their starting and running watts from the chart.
  3. Add up the running watts of all appliances.
  4. Identify the highest starting wattage of any appliance.
  5. Ensure your generator meets or exceeds these wattage requirements.


Example:

If you want to power your refrigerator (starting 2,200W, running 800W), sump pump (starting 2,150W, running 1,050W), and some lights (4 bulbs x 60W = 240W):


- Total Running Watts: 800W + 1,050W + 240W = 2,090W

- Highest Starting Watts: 2,200W (refrigerator)


Your generator should have at least 2,090W running capacity and handle a surge of 2,200W.

Understanding Your Generator’s Capacity

Choosing the right generator requires careful consideration of your power needs. By calculating the total running and starting watts for your essential appliances, you can ensure your generator will handle the load efficiently. Keep in mind that some appliances, like refrigerators and sump pumps, have higher starting wattages, which can affect your generator's overall capacity. It's important to match your generator's capabilities with the wattage requirements of your home to avoid overloading.

Generator Safety Practices

Safety is paramount when operating a generator. Proper usage not only protects your equipment but also safeguards your home and family. Here are some essential portable generator safety tips:

Proper Installation:

Always have your generator inlet installed by a licensed electrician to ensure compliance with local codes and safety standards.

Ventilation:

Operate generators outdoors in well-ventilated areas to prevent carbon monoxide poisoning. Never run a generator inside your home or garage.

Use Appropriate Cords:

Utilize heavy-duty, outdoor-rated extension cords that match or exceed the amperage of the connected devices.

Regular Maintenance:

Follow the manufacturer's maintenance schedule, including oil changes and filter replacements, to keep your generator running safely and efficiently.

Fuel Storage:

Store fuel in approved containers away from living areas and heat sources. Turn off the generator and let it cool before refueling.

Frequently Asked Questions


  • Generator inlet with interlock kit vs. manual transfer switch, which is better for me?

    Both options have their advantages. An interlock kit is typically more cost-effective and uses your existing electrical panel, while a manual transfer switch allows you to select specific circuits to power. We can assess your needs to recommend the best option.

  • Can I use any portable generator with the inlet box?

    Yes, as long as the generator's output matches the inlet box rating (30-amp or 50-amp).

  • How long does the installation take?

    Installation typically takes several hours to one day, depending on your home's setup.

  • How much of my house can I run from a portable generator?

    It depends on the wattage of your generator. Common items include refrigerators, freezers, lights, TVs, gas furnaces, on-demand water heaters, and general-purpose receptacles.

  • What can I not run from a portable generator?

    High-demand electrical equipment that can overload a portable generator includes electric strip heaters, large air conditioning units, and electric ovens.

  • What is the difference between an interlock kit and a manual transfer switch?

    An interlock kit allows you to safely switch your main electrical panel between utility and generator power, preventing both from operating simultaneously. A manual transfer switch is a separate panel that directs power from your generator to selected circuits.

  • Can I install a generator inlet box myself?

    For safety and compliance with local codes, it's recommended to have a professional electrician install your generator inlet box.

  • How much does it cost to wire my house for a portable generator?

    The cost varies depending on the setup, your power requirements and distance from the generator inlet to the electrical panel. Contact us for a free estimate.
