DC Supplies - 08/30/01 05:33 PM
Does anyone know when the old DC supplies disappeared in America?
We had them in England in the older parts of many towns well into the 1950s, and I believe the last public DC supplies were converted in the 1960s.
That was before standardization at 240V, so the DC mains were anything from 200/400 to 250/500V.
