Hint, there is more than one electrical violation. This is a plenum space inside a condo hallway closet that houses the water source heat pump for an R2 dwelling unit. How many do you see? Hint 2, they used a disconnect as a power source for the low voltage system they added to the mechanical system.

If this is inside an individuals condo/apartment then I would have a difficult time calling it a "plenum" not saying there are not electrical violations, just saying the violations may not be related to the plenum requirements

I see some exposed wires that may not be plenum rated. If that is the air handler on the right in the bottom picture with a bottom return then just box in the return and the room is no longer a plenum. I installed thousands of air handlers in Dade, Broward and Palm Beach county condos back in the day and all of them the return was boxed in and not open to the room/closet the air handler was in. Most looked like this. Perhaps someone removed part of the original installation and created this plenum. Is it an easier and cheaper fix to eliminate the "plenum" then to call out the electrical violations if the only violations are due to the plenum requirements is what I am asking? 1600179819366.png
