Please give me your thoughts regarding the use of a rubber cord connected directly the (standby) terminals of a transfer switch (suitable for service equipment) with a male plug attached to the other end of this cord. This cord is also routed trough a section of flexible conduit that is a little shorter in length that the cord so that the plug can be attached to the cord. The electricians reasoning for the flexible conduit is to protect the rubber cord from UV rays. This cord is plugged into a generator that is mounted on a trailer next to the (Fire Station) building for standby purposes or hanging on the building if the generator is relocated. The focus of this question is the rubber cord and assuming all other is compliant.

You probably want something like SEOW cord—sunlight resistant, wet-rated, flexible at cold temperatures, and generally suitable for use outdoors. Related article: http://www.nmsu.edu/~tdi/cc66.pdf

The trailer-mounted generator set may need a receptacle and cover that is for “wet location while in use.”

A 3R hinged-cover can nippled to the transfer switch for not-in-use storage of supply cord has worked well for me. It's likely someone has to approach the set for startup and shutdown anyway.

{The flex seems like a misapplication—I don't think it could effectively protect the supply cord from sunlight deterioration. IMO, a sunlight-resistant grade is mandated for the duty at hand.
