Selecting The Right Standby Generator

Sizing And Code Requirements

(HIT) - If you are considering a backup generator purchase, there are important sizing and code requirements that you need to know to insure a safe and adequate standby generator installation. Sizing the generator takes into account the total kilowatt (kW) requirements of the electrical equipment to be served. Undersizing can leave you frustrated while oversizing is just a waste of money.

Consider Any Motor Loads

Pay particular attention to anything with an electric motor. Starting a motor requires three to seven times the current used during normal operation. Allowing for this startup or inrush of current when sizing the generator is crucial.

Use A Double-Throw Switch

Electrical connections to the wiring system of the home, farm, or business require a double-throw transfer switch. This is not a do-it-yourself project! Involve an experienced electrical contractor to insure a safe, reliable installation that meets all local and national code requirements. Another safety consideration is where the generator is placed. Unless you vent the generator fumes to the outside, never locate it inside a building, garage or basement.

Helpful Publication

A new publication is now available that contains a wealth of information about standby generators. Called "Sizing and Selecting Your Standby Generator," this 20-page illustrated guide helps homeowners, farmers and small business owners correctly size and safely install standby generators. It explains the various types of generators available, such as engine or tractor driven, portable or permanently anchored units. Three examples are provided to illustrate proper matching of the electrical capacity to the particular load requirements. One section is devoted to the need for a double-throw transfer switch. Also the names, locations, and phone numbers of 32 major generator suppliers are included to assist readers with the selection process.

To purchase the booklet, call the National Food and Energy Council (NFEC) at 937-383-0001 or fax 937-383- 0003, mentioning "Sizing and Selecting Your Standby Generator." The price is $9.75 (includes shipping and handling). Learn more about this, and other electrical topics at http://www.nfec.org.
