face=Arial>110 volts was Edison's choice for direct current. Then
Tesla/Westinghouse chose higher voltage alternating current stepped down to 120
volts. See <A

AC/DC universal motors in drills and other tools were fairly common until
low-cost induction motors became widespread.</FONT></DIV>

<DIV>When I was an electrical apprentus back in the late 40's we called
it 110/220 then in the fifties the voltage was reised to 115/230
and some time in the 1960 it was raised to 120 240 </DIV>
