Well, 400.8(5)seems to restrict the use of flexible cord from above a dropped or suspended ceiling...
But, the restrictions of 400.8 only apply to installations not allowed by 400.7
So, wouldn't 400.7(6) allow equipment such as a condensate pump with a manufacturer installed flexible cord and attachment plug be allowed to be pluged into a receptacle outlet as described in 400.7(B)
Nothing would restrict the installation of a receptacle outlet above a dropped ceiling and if the flexible cord were not installed as a permanent wiring method than IMO, it would be a code compliant installation.
