If supplied from an ungrounded (two-wire) receptacle, the two lines will float at about 60 volts above ground ... one half of the nominal 120 volt line to neutral voltage. The primary side of the switching PSU makes no assumption about this and is perfectly fine with either grounded or floating input. All it cares is that the two lines are 120 volts between them. Indeed, the input voltage is first doubled to 325 volts dc and is subsequently converted to +5, +3.2, +12 and -12 volts, as required. -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
