What is the reason for newer plugs having different sizes?
Answer One connects to neutral wires while the other connects to "hot" wires
Having different sized prongs is a great innovation. It means there is only one way to connect to the outlet, so one connects to neutral wires while the other one connects to "hot" wires.
