Having the ground down will keep a persons index finger from touching the live pins. These slots correspond to the hot, neutral, and ground wires. If current is flowing into the positive part then the device the plug is attached to is receiving power (would be a little against standard use of these kind of plugs). In other words, for one reason or another, the white wire is hot rather than neutral, and the black wire is neutral instead of hot. 1 Pushbutton.
