You mentioned buying a motor STARTER cap.  Don't - you need a motor RUN cap.
A starting cap is an electrolytic cap and will smoke in a few minutes if
left powered continuously.

PFC cap users,
 
I am trying to improve the efficiency of my NST by adding a PFC cap.  The
formula I have for this is:
 
PFC value in uf=KVA ((10^9/(2*3.14*f*e^2)) or PFC value = (Volt amp rating
divided by 1000) multiplied by the coefficient of (10 to the 9th) divided by
(2pi Frequency (voltage squared))  
 
Where frequency= the operating frequency of the NST
              voltage= NST primary input voltage
 
I have a 360 Volt Amp, 60Hz NST and I will be running between 120 and 145
VAC
in.  Before I go buy a motor starter cap will someone on the list with PFC
know-how confirm that I am on the right track?
 
 
Thanks 
--Nathan
