Do you have the Handbook version of the code? It has some more clear definition on your situation. But I would have to cut and paste whole thing for a clearer picture.
This is the commentary after 695.4, I hope this helps, as I'm not quite sure what exactly your question is.
Typically, the supply conductors of the power source are directly connected, without a disconnecting means or overcurrent protection, to the fire pump controller or combination fire pump controller and power transfer switch. However, a single disconnecting means is allowed, provided all the conditions in 695.4(B), Supervised Connection, are met.
In addition to the fire pump controller, where a separate service disconnect with overcurrent protection is provided for the fire pump circuit, the disconnecting means will be as follows:
(1) The overcurrent device is sized to carry the locked-rotor currents of all the fire pump motors.
(2) The fire pump disconnection means is located away from the other service disconnecting means. This disconnecting means is rated as service equipment and is lockable in the on position.
(3) The disconnect and controller is marked and placarded as described.
(4) The circuit is supervised in the closed position, in accordance with 695.4(B)(5).
Specifically, the size of the overcurrent protective device is the sum of the locked-rotor currents of all the permitted motors plus the sum of any other fire pump auxiliary loads.
Example
A fusible service disconnect switch supplies power to a 100-hp, 460-volt, 3-phase fire pump and to a 11/2-hp, 460-volt, 3-phase jockey pump. The fire pump feeder circuit will be installed in a raceway between the disconnecting means and fire pump controller. The raceway is considered outside of the building per 230.6. Using the requirements of Article 695, determine the sizes of the disconnecting means and overcurrent protection device.
And this from 695.3
Most important in 695.3(A)(2) is the requirement that a fire in one source not affect the reliability of another source. For example, if an emergency feeder were physically routed above the normal switchboard and a fire occurred in the normal switchboard, the reliability of the emergency feeder during the fire would be questionable. There are many other examples for such interruption scenarios. The requirements for fire protection of the fire pump supply conductors are located in 695.6(A) and (B)
As for controler and T-switch location see 695.12
Hope all of this helps..... From what I gather of the code, and commentary is that the conductors/conduit feeding the pump should be as fire/bomb proof as possible. The last one I did was some time ago and was all outside the building all together. Transfer switch, seperate gennie and pump all fenced in a shed together. (Seperate from the other gennies, which I thought odd at the time.)
