In the single line diagram shown, the current is not to exceed 125% of the load. Using the TCC Curve below, find the time (in seconds) it would take for the relay to trip the CB for an overload current of 400% of the load if a time dial setting 1/2 of the overcurrent relay is used. Submit computation. Write your answer in numerical format (round off to two decimal places).
