When looking at filter caps for AC/DC sets measure your incoming line voltage (mains voltage) and divide by .707 to get the peak voltage on the line. For North Florida my line voltage runs app. 123.9 most of the time, 123.9 divide by .707 = 175.24 volts. So on AC/DC sets I will use 220-250 volt rated caps with a high ripple current temp rating of 105C. I only want to do this once
