The selection of a ringing generator is sometimes a frustrating and somewhat haphazard guessing game due to a lack of familiarity and experience by the person responsible for the choice. The author describes a logical process to simplify the selection of central office and controlled environment vault (CEV) ringing generators based on available input power source, output frequency and power capacity, operating temperature range, and whether single or redundant generators will best meet the needs of the served load. Additional information is presented, and guidelines are given to assure that the selected generator will be correctly installed. Input feeder size and fusing, output return connection, output distribution fusing, and mounting location are discussed. The selected generator will perform as expected with a minimum of subscriber trouble reports.<>
