Non-grounded conductors entering a building

I am familiar with ungrounded entering a building requiring a service disconnect, however I have an application that I couldn't find a real answer to in the code.
I have an industrial "maintained and supervised site" that has a small concrete building that houses a pump (not a fire pump) 460V 3-P, and it is fed from an MCC located in the adjacent process building. By NEC 2005, do the motor feeder wires require a disconnect in the pump building? Further, what if I had 2 pumps? What about lighting for the pump house?
I would assume that if all 3 (2-pumps and lighting circuit) would each need their own disconnect. Any discussion to ensure that I am not overkill?
 
Welcome to the Forum:

The short answer lies with 225.30:
225.30 Number of Supplies. A building or other structure that is served by a branch circuit or feeder on the load side of a service disconnecting means shall be supplied by only
one feeder or branch circuit unless permitted in 225.30(A) through (E).

225.32 goes on to say

225.32 Location. The disconnecting means shall be installed either inside or outside of the building or structure served or where the conductors pass through the building or
structure. The disconnecting means shall be at a readily accessible location nearest the point of entrance of the conductors. For the purposes of this section, the requirements in 230.6 shall be utilized.

HOWEVER. In your situation:

Exception No. 1: For installations under single management, where documented safe switching procedures are established and maintained for disconnection, and where the installation is monitored by qualified individuals, the disconnecting means shall be permitted to be located elsewhere
 
Thanks for the quick reply, I am familiar with this Exception No. 1: For installations under single management, where documented safe switching procedures are established and maintained for disconnection, and where the installation is monitored by qualified individuals, the disconnecting means shall be permitted to be located elsewhere, but was unsure what them meant by "located elsewhere". Could that mean an adjacent building, or purely at the discretion of the AHJ?

I believe it could be next door, but want to try to take a relatively conservative approach to prevent a possible change-order.
 
The last words of the exception were left off the quote: "on the premises"
In my opinion the remote disconnect can be anywhere on the property.
