Open circuit current over rated current

Webwhere the available short-circuit current exceeds the downstream circuit breaker’s interrupting rating. The term given to this is a series rated combination, series rating, or series combination rating. The application of series ratings has many technical limitations and additional NEC® requirements that must be met for proper application. WebFigure 2 shows the experimental concept for the open-circuit and short-circuit tests. Figure 2: (a) Instrumentation for open-circuit test. (b) Instrumentation for short-circuit test. The open-circuit test is run at rated voltage and yields the following quantities; I oc = exciting current as read by ammeter A. V oc
