When I worked on wiring a new combined dentist and dermatologist clinic a few years ago, we used the HFC cable for everything in the patient care/exam rooms, including the chair and overhead exam light unit. We had a full basement below to work with in that situation though.
I also ran some EMT for a large branch circuit to one of the dermatologist’s treatment rooms where they had some kind of UV booth used to treat skin conditions like psoriasis.
If it’s in an above grade slab, I wonder if maybe the EC was planning to use that PVC as a sleeve to pull his HFC through later.
