WHAT TO KNOW BEFORE CHOOSING A BACKUP GENERATOR
You will need to know the following information before choosing a backup generator for your property:
THE DIFFERENCE BETWEEN STARTING AND RUNNING WATTAGE
Before calculating your wattage requirements, it is crucial to understand the differences between starting and running wattage. Also known as surge watts, starting wattage is the amount of electricity or power that is required to start a device. For most devices, the amount of power you need to start them will be equivalent to three times the running wattage amount. Running wattage is the amount of electricity that is required to keep the device running smoothly after it has been powered on. For example, when you power your television on, it will use starting watts as it powers up and then transition to running watts as the unit stays on.
YOUR WATTAGE REQUIREMENTS
The next thing you will need to know when selecting a generator is the wattage requirements of your home. To determine your wattage requirements, you will need to add up the wattage of everything you wish to power via your generator. This may include lights, appliances, a device charger, electric heaters, or your air conditioning system. The more devices and appliances you wish to use, the more wattage you will need. The list below outlines the approximate running wattage rating for various household appliances and devices:
- Refrigerator/Freezer: 600 – 800 watts
- Electric Range (one element): 2,500 watts
- Toaster: 1,100 – 1,700 watts
- Microwave: 800 – 1,200 watts
- Coffeemaker: 400 – 800 watts
- Electric Oven: 5,000 watts
- Television: 100 – 350 watts
- Personal Computer: 300 – 2000 watts
- Central Air Conditioning: 2,000 – 4,000 watts
- Electric Water Heater: 3,000 – 4,500 watts
- Water Pump: 1,000 – 2,000 watts
- Window Air Conditioner: 600 – 1,500 watts
- Outdoor Lighting: 500 – 1,000 watts
- Sump Pump: 1,200 – 1,800 watts
- Hair Dryer: 1,200 – 1,500 watts
- Vacuum: 700 – 1,400 watts
- Electric Space Heater: 1,000 – 1,500 watts
- Table Lamp: 150 watts
- Electric Furnace: 5,000 – 25,000 watts
It is crucial to remember that each device above will require roughly 3 times the listed amount to power on. For example, an electric heater will require 3,000 to 4,500 watts to start, but only 1,000 to 1,500 to continue running.
