    Abstract: Unique systems, methods, techniques and apparatuses of inrush current detection and reduction are disclosed. One exemplary embodiment is a method for transmitting power to a load comprising operating a solid-state switching device of a power distribution network device with a microcontroller-based controller, the solid-state switching device including a gate and structured to receive a signal with the gate so as to control the switching device to receive power from a power source and selectively provide power including an output current to the load; detecting an overcurrent condition in the output current; operating the solid-state switching device in order to determine the load is a capacitive load in a charging condition in response to detecting an overcurrent condition; and operating the solid-state switching device so as to reduce the magnitude of the output current during the charging condition.
