f.
Protective devices - A description shall be given and the following illustrations included:
(1) A circuit breaker coordination chart shall be prepared showing the time-current characteristics of all
the circuit breakers used in series from the generator to the load on a representative feeder. The bus
tie circuit breakers shall be plotted on log paper and shall cover the complete range from the long time
delay pickup value of current of the smallest breaker to the instantaneous trip point of the breaker with
the highest setting.
