Special substation designs to achieve high reliability may utilize multiple circuit breakers, as shown in Fig. 1. Less expensive designs may use protection only in series with the feeders, as shown in Fig. 2. In these figures, switches and circuit breakers are normally closed unless there is a “N.O.” (normally open) indicated beside it.
