Greg,
They are white looking right? I know I am most likely repeating myself, but years ago I was doing an inspection and the lady asked if she could cover a small portion of a trench in order to get to a shed or a garage. I said she could cover a small part but not too much. Well when I looked in the trench the next day, there was all the white plumbing pipe good for 90 PSI. She was not happy when I failed her and me and my big mouth. I said that it was the wrong pipe and an EC would know that. Then she looked at me and said her husband WAS an electrician.
My guess was that he was either a handy man or maybe a maintenance guy who just changed bulbs. Anyway, I have learned to keep my big mouth shut. (I think)
