摘要： A circuit interrupter includes an electronic trip unit structured to receive power from a power supply. The electronic trip unit includes a start-up process and is structured to proceed through the start-up process when the electronic trip unit begins receiving power from the power supply and a timing circuit including a capacitor structured to begin charging when the electronic trip unit begins receiving power from the power supply. The electronic trip unit includes a processor that is structured to read a voltage across the capacitor when the start-up process has completed and to determine an elapsed time of the start-up process based on the read voltage across the capacitor.
