   J.B. Wood to All   
   1950s MV Distribution

   Hello, everyone.  I was browsing some old 1950s street photographs of   
   the Cincinnati suburb of my youth and was curious about the medium   
   voltage (MV) lines seen on the utility pole cross arms.  Unlike most of   
   the present day 3-phase MV runs in the U.S. with 3 wires on a crossarm   
   and the neutral carried lower on the pole, the photos show poles each   
   having a top cross arm with 4 wires and a lower cross arm with 2 wires.   
   Below them are what look to be 120/240 LV wires.  None of the old photos   
   clearly show the connections for a pole-mounted MV-LV distribution   
   transformer.  So for anyone with an historical knowledge of these   
   methods your comment is greatly appreciated.  Sincerely,   
   --
