I am running a 15/30 NST and need to know the size in mfd of cap i should use and how many. Also, the ones that i saw at USA Manufacturing were very high in volts. most of them were 370. perhaps i was looking at the wrong thing. they said run caps on page 36-37 of the USA Mfg. catalog. any help would be great. thanks tyler tsgeoman-at-uswest-dot-net
