Joseph,

  Thanks for the follow up.

MrFixr55,

  Thanks for the info. I was aware of the "Current Wars" between Westinghouse and Edison (I have the movie, although I am not sure how "technically accurate" it is other than in general). The 1893 Columbia Exposition seemed to be at the time the move to AC distribution really got under way.

  I had expected that any residential users of 110v DC would have to be in large cities, near where electric street cars and street ARC lighting were in use, because the generation facilities for these would be nearby.
Regards,   PeterN
