Hi William..


a PFC cap is a capacitor that is normally used before the load ( NST
etc) it is wired in paralell with the 120V system  altho most PFC caps
are of low values ( uF wise)  you end up having to parallel several
together to get a hi enuf value to be effective 

if you are looking for PFC caps   be sure to look for "Motor Run"  caps
...  the "motor start" caps are cheaper for the amount of uF but... 
they dont hold up well in extended usage ( motor start caps are used for
a brief moment when the motor starts, then they switch off)(( they just
offer a surge to help out starting torque))

most motor run caps are  oval shaped and about 2 times taller than they
are wide  usually they are in a metal case too ...
