ABSTRACT:
A transfer switch having a transfer control provides electric power to a load. The transfer switch includes a power switching device provided with electric power from a first power source, such as a utility power source, and a second power source, such as a generator power source. The transfer control is structured to monitor the second power source, maintain a runtime count of the second power source, locate a piece of data concerning a maintenance procedure in a storage corresponding to a current value of the runtime count, and provide an indication of a need to perform the maintenance procedure.
