How does a 3 wire 110 v. system operate??
HI, I am just curious as to what the difference is in the older 2 wire household electrical wiring and the current 3 wire (black (hot), white (neutral) and bare copper (or green?) ground lead. Am I correct that in the old 2 wire systems that the fuse would blow only if both conductors shorted together?? And am I correct that in the 3 wire system that if either the
black or white was shorted to the ground side (for instance if a short inside an applicance put either the black or white to ground) , then the breaker would trip.?
Also, I'm confused as to why the white is always connected in the service panel to the terminal block that also has all the ground conductors attached to it. Thanks for the help, Steve
