480V. single THWN conductors run to a roof mounted HVAC unit in conduit in the building, but the conduit stops at the bottom of the unit. The conductors are then run freely in the fan/coil and compressor section of the unit, through a nipple to the disconnect and then through the same nipple up to the termination point for the conductors.
I obtained the installation manual for the unit and it does not specifically tell how to route the conductors. The owner (a school district) is concerned with the safety aspects of working around the 480V. exposed conductors during maintenance. I am looking for ammunition to include in a letter citing the concerns and possibible code violations hoping to convince the contractor to fix the installation. The control wiring was installed in seal-tite flex.
Our specifications (electrical engineers) state that all wiring shall be run in raceway, which is one of my arguements. Citing specific code paragraphs would help the cause and here is where I would like help. Any help would be greatly appreciated.
Thanks.
