@CurtisH posted:I just did an inspection on a house that sold and it was all DC voltage. Also our friend in Morristown NJ , her father (I believed he lived in Schnecksville PA) had an ALL DCC voltage house.
On that note, about 25 years ago I inspected a loft industrial building in Chicago that had DC elevators in it. The building has since been converted to loft offices, so I would guess the freight elevators are either gone or converted to operate on AC. That is still not the craziest elevator story...
I recall seeing a different loft industrial building that was constructed in the late 1870s, shortly after the Great Chicago Fire, which still had its original bird-cage elevator with hand operated controls. That was a hoot!
