The sensor is configured to detect a presence of at least one entity or arc flash protection qualifying event in proximity to the generator set. The controller is configured to initiate an arc flash protection regime when the presence of the at least one person or arc flash protection qualifying event is detected in proximity to the generator set. The arc flash protection regime includes shutting down the generator set automatically upon detection of a short circuit.
