Primary Injection Testing Requirements (NEC 230.95)

WebThe two methods of breaker testing are: (1) Primary Injection Testing injects a high current through the breaker to test the current path and the functionality of the breaker. (2) Secondary Injection Testing injects a low current through the tripping mechanism to verify the trip characteristics in the event of an overload or fault condition. WebPrimary Injection Testing. The ERMS function can be tested through primary injections means. Use EcoStruxure Power Commission software to prepare the circuit breaker for primary injection testing. The "Prepare for Primary Injection" button allows access to the "LSI Protection" and "Ground Fault Protection" functions. These functions are used for: green corn chips
