Common Power Generator FAQ’s


🔌 What is an Electric Generator?

Electric generators work to provide electricity when power from the local electrical grid becomes unavailable due an emergency or other outage. A generator is typically a standalone machine installed outside the home.


🔌 How Does an Electric Power Generator Work?

Home power generators convert mechanical energy into electrical energy. Using fuel sources like gas, diesel and propane, an electrical current gets established and directed through copper wires to provide power to machines and devices, often powering entire properties.


🔌 What Size Home Generator is Needed to Power a House?

Determining the size of the generator you need for a home comes down to the number of watts needed to power specific appliances. You’ll want to choose a size that can provide electricity for refrigerators (typically 700-800 watts), AC units (1,000 watts), washing machines (1,200 watts) and many other appliances that could require much more power.

The most common sizes for residential electrical generators include:

  • Recreational – up to 2,000 Watts
  • Midsized – up to 3,500 Watts
  • Large or Portable – up to 7,500 Watts
  • Whole Home – up to 20,000 Watts
