The nameplate is inside the panel. The model number of the control panel is based on panel options and generator ratings. The model number is defined further by the following charts.1. The first character of the model number is a "B". This indicates a conventional electro-mechanical control panel. This also indicates the panel is mounted in the side of a standby package generator set. It further indicates the system is equipped with an auto start-stop control.2. The second character of the model number indicates the engine type used.
