On the 2/3 conductor line cord: If you look at the schematic - there are two (2) 0.01uF safety caps in series with a ground between them - which is the same common ground throughout the system. And, by the way, those are X-types as the are between the hot and the neutral.
** Weicky has wanked himself blind.
Those two cap are *OBVIOUSLY* connected from hot AC wires to ground.
Y class caps with not common back in the day.
