How does a whole house generator work?
Home generators are smaller than the generators used in commercial and industrial applications, but work in the same way, and have the same components. The best way to install a home generator is to connect it to the home’s main electrical panel, so it can power all of the home’s electrical circuits when needed. This is done with a device known as a transfer switch. The transfer switch prevents electricity from traveling from the generator and into the power lines, so utility workers don’t risk getting an electric shock from someone’s home generator when they are working on the lines.
Most homes use generators as standby power. In case of an electrical outage, the generator senses the loss of power and automatically kicks in, usually within seconds.
Portable generators are scaled down versions of home generators and feature an engine roughly half the size of a lawnmower engine. Many portable generators weighing 50 pounds or less are available. Their portability makes them well suited for camping trips, cookouts, and construction projects.
Modern portable generators come with standard AC outlets and USB charging ports. Some even have Bluetooth connectivity and an app that allows the user to monitor the status of the generator on a smartphone. Others have built-in batteries which provide power for some time without having to start up the engine. Portable generators must never be used indoors, inside a vehicle or inside a tent because they can release deadly carbon monoxide gas.

What appliances and necessities can you run with a home standby or portable generator?
Here's a general guide to what you can power with different size generators. (For simplicity, these examples use approximate power needs of appliances. The actual power consumption of your appliances could vary.)
What can a 9,000-watt generator power?
This range of power needs means you can probably use a portable generator instead of a whole house generator. A 9,000-watt portable generator can run one of the following combinations, but not both at the same time:
- Refrigerator, microwave oven, electric stove and dishwasher, OR
- Central AC in smaller homes, washing machine and iron
What will a 13,000-watt generator run?
This size generator is a great entry level generator to power rooms of your choice. A 13,000-watt generator could power all the following basic amenities:
- Central air conditioner
- Electric water heater
- Gas furnace
- Electric garage door
- Refrigerator
- Freezer
- Microwave
What can you run with a 20,000 watt generator?
A 20,000-watt home standby generator is ideal for powering the whole house through an outage, especially if you have a larger home or longer outages. A 20,000-watt generator could power the following essentials in addition to the list above:
- Dishwasher
- Washer
- Dryer (Electric)
- Cooktop (Gas or Electric)
