Types

• There are two basic types of home generators: Portable and permanent. Small portable units are typically less expensive but are not designed for long-term use. Permanent generators are often installed for extended use in power outage emergencies.
  
  

Fuel

• Several fuel types are available. Many portable generators run on standard gasoline, allowing them to be filled as needed. Permanent standby generators commonly run on propane or natural gas, allowing them to be directly integrated into a home.
  
  

Installation

• Generators must be installed outside, usually on a concrete slab away from the house. A minimum of 10 feet should be between the generator and the home, ensuring adequate ventilation of exhaust fumes.
  
  

Wiring

• A generator is connected to the home using a transfer switch. This allows power from the generator to flow into the house but not into the outside power system. A licensed electrician should install all generator wiring to ensure safety and compliance with housing codes.
  
  

Buying

• Many home improvement supply stores carry a wide selection of portable and permanent generators. These locations often have knowledgeable experts to compare models and find the best fit for each application.
