IEEE 1015-1997

To develop a publication that represents standard practice in the US for applying low voltage molded case and power circuit breakers uses for industrial and commercial power systems. This guide does not cover circuit breakers such as ground fault interrupters, marine, definite putpose, supplementary and DC circuit breakers.

To assist engineers in the proper application and selection of low voltage molded case and power circuit breakers used in industrial and commercial power systems. This guide will help the application engineer specify the circuit breaker type, ratings, trip functions, accessories, acceptance testing and maintenance, applying circuit breakers at different locations, and protecting specific components.

New IEEE Standard - Superseded. Superseded by IEEE Std 1015-2006 Information is provided for selecting the proper circuit breaker for a particular application. This recommended practice helps the application engineer specify the type of circuit breaker, ratings, trip functions, accessories, acceptance tests, and maintenance requirements. It also discusses circuit breakers for special applications, e.g., instantaneous only and switches. In addition, it provides information for applying circuit breakers at different locations in the power system, and for protecting specific components. Guidelines are also given for coordinating combinations of line-side and load-side devices.
