NEC 695 does not require rating outside of a building. They do, however, require protection from potential damage. Will they be routed in an area subject to digging or vehicle traffic?

You'll have to give us a better description for the normal power source. It sounds like you are not providing the connection ahead of the main, but via branch circuit. And about the need for a step dwn - is it 208?

There are many other aspects to fire pump installations also. What occupancy type is this? Building height?
