"Across-the-Line" and "Line-to-Ground" Capacitors
X2 Capacitors are more often used in more general applications. Another type of "safety" capacitor that suppresses RFI is a Y Capacitor or "Line-to-Ground" Capacitor. Unlike the X Capacitor, the Y Capacitor is designed to be connected between a current carrying conductor and a grounded conductor. The X Capacitor, on the other hand, is ...
Y Capacitor
An X2 capacitor can be safely substituted for a Y2 capacitor, however a Y2 capacitor should not be substituted for an X2 capacitor. This is due to the fact that, while an X2-type capacitor would function and filter noise adequately, it would not fulfill the line-to-ground safety criteria. Safety capacitors of the Y2 series are more durable, can handle greater peak …
capacitor
A capacitor in an AC circuit forms a current limiter because when current flows one way the capacitor lets it pass until the capacitor is charged in one polarity and then when the current is reversed the capacitor discharged and lets the current flow the other way. The amount of current depends on the capacity of the capacitor and the frequency of the AC.

These capacitors are known as "Y capacitors" (X capacitors on the other hand are used between mains live and mains neutral). There are two main subtypes of "Y capacitor", "Y1" and "Y2" (with Y1 being the higher rated type). In general Y1 capacitors are used in class 2 equipment while Y2 capacitors are used in class 1 equipment.

Electrical Grounding Using the Isolated (or Ungrounded) Method
Before the ground-fault, the neutral of the ungrounded system remains close to ground potential, blocked there by the balanced capacitance of the three phases. The fault causes the neutral to shift in potential, and a line-to-line voltage appears throughout the system between the ground and the two unfaulted lines — a 73% increase — until clearing the fault. …

When does and when doesn''t current flow to ground?
The key point is that the current flows from one point of the circuit, through ground, then back into the circuit. With only one connection to ground there is no circuit for the current to flow through. It can''t flow "to" ground, because there is nowhere for it to flow to. There''s no difference between ground and a wire dangling in the breeze.
