Is this allowed (and, if so, why)?

Pictures speak for themselves.

BTW, equipment is in a flood zone - water mark up about 3" on some other equipment in the room.

110.3 Examination, Identification, Installation, and Use of Equipment.
(A) Examination. In judging equipment, considerations such as the following shall be evaluated:
(1) Suitability for installation and use in conformity with the provisions of this Code

FPN: Suitability of equipment use may be identified by a description marked on or provided with a product to identify the suitability of the product for a specific purpose, environment, or application. Suitability of equipment may be evidenced by listing or labeling.
(2) Mechanical strength and durability, including, for parts designed to enclose and protect other equipment, the adequacy of the protection thus provided
(5) Heating effects under normal conditions of use and also under abnormal conditions likely to arise in service
(7) Classification by type, size, voltage, current capacity, and specific use
(8) Other factors that contribute to the practical safeguarding of persons using or likely to come in contact with the equipment

(B) Installation and Use. Listed or labeled equipment shall be installed and used in accordance with any instructions included in the listing or labeling.

110.11 Deteriorating Agents.
Unless identified for use in the operating environment, no conductors or equipment shall be located in damp or wet locations; where exposed to gases, fumes, vapors, liquids, or other agents that have a deteriorating effect on the conductors or equipment; or where exposed to excessive temperatures.

FPN No. 1: See 300.6 for protection against corrosion.
FPN No. 2: Some cleaning and lubricating compounds can cause severe deterioration of many plastic materials used for insulating and structural applications in equipment.

Equipment not identified for outdoor use and equipment identified only for indoor use, such as “dry locations,” “indoor use only,” “damp locations,” or enclosure Types 1, 2, 5, 12, 12K, and/or 13, shall be protected against permanent damage from the weather during building construction.

FPN No. 3: See Table 110.20 for appropriate enclosure-type designations.

Location, Wet. Installations underground or in concrete slabs or masonry in direct contact with the earth; in locations subject to saturation with water or other liquids, such as vehicle washing areas; and in unprotected locations exposed to weather.

I would not approve of such an installation, but it may or may not be a violation of the NEC. I have seen similar transformers legally installed outdoors in wet locations, and the only difference is you had to attach a kit to the top of the transformer to make it Type 3R. I do however find it difficult to believe that any inspector would allow this. Also since it is a flood zone, submersion comes in to question.......
 
There may be other restrictions outside of the NEC that I am not aware of. I'm sure there's something, somewhere, about blocking drains in a flood zone?????
 
FEMA regulates flood zones

FEMA regulates flood zones

FEMA prohibits installation of electrical equipment within a flood zone except for very limited and specific instances, such as maintenance receptacles. I had a project where FEMA inspected a building, called the insurance carrier, and the insurance carrier forced the client to relocate the gear or lose coverage.

Is this component rated for underwater operation? If not, it is a mis-application.

I agree with this assessment.

110.20 lists two possible candidates, and the transformer in the picture is not one of them.

110.20.....Type 6 and 6P

FEMA requirements restrict most electrical equipment from being located in a flood-zone.

We have had instances where the outside disconnect had to be mounted up higher than the 6'-7" restriction set forth by section 240.24(A). In those cases, a working platform had to be constructed with appropriate railings and steps for proper access.
