Residential generators are typically smaller than those used for commercial and industrial purposes, but they function in a similar manner and share identical components. The optimal way to install a residential generator is by connecting it to the main electrical panel of the home, enabling it to supply power to all of the household's electrical circuits when necessary. This connection is facilitated through a device known as a transfer switch, which safeguards against electricity flowing from the generator into the power lines. This precaution ensures that utility workers are not exposed to electric shock hazards from residential generators while working on the power lines.

In most cases, residential generators are utilized as standby power sources. When there is a power outage, these generators automatically detect the loss of power and activate within seconds.

Portable generators, on the other hand, are downsized versions of residential generators and are equipped with engines approximately half the size of a lawnmower engine. There is a wide range of portable generators available, with many weighing 50 pounds or less. Their mobility makes them ideal for activities such as camping trips, outdoor gatherings, and construction projects.

Modern portable generators are equipped with standard AC outlets and USB charging ports. Some even feature Bluetooth connectivity and a smartphone app for monitoring the generator's status. Additionally, certain models have built-in batteries that can supply power for a period without needing the engine to start. It is essential to note that portable generators should never be operated indoors, within a vehicle, or inside a tent, as they can emit deadly carbon monoxide gas.

This generator size serves as an excellent starting point for supplying power to selected rooms. A 13,000-watt generator has the capacity to support essential household appliances and amenities, including:

Central air conditioning system
Electric water heater
Gas furnace
Electric garage door opener
Refrigerator
Freezer
Microwave

A 20,000-watt residential standby generator is the perfect choice for maintaining power throughout your entire home during an outage, particularly if you have a larger residence or experience extended periods without power. In addition to the previously mentioned list, a 20,000-watt generator has the capacity to provide power to essential appliances like:

Dishwasher
Washing machine
Electric dryer
Gas or electric cooktop
