NEC does not care about the internal of a fire pump controller. NEC governs the wiring to and from the controller. When inspecting, the AHJ will look for the controller listing, and maybe a few more items if he/she is not familiar with the controller.
The one fire pump controller for a 100 HP pump (one is enough!) I installed had 2 250 amp breakers in series to meet short circuit requirements.
Fire pumps are a different beast, they are painted red, are a lot more expensive than a non fire pump controller, and the fire marshall is the one who really looks over the install...and tests everything
