I have a 30 amp, 3 phase EMI-RFI line filter that was given to me and I'm interested in using it for a 120v NST powered Tesla coil. Does anyone know If I can use a 3 phase filter in a single phase application? (Will the two unused legs of the filter interfere or prevent the one active leg from doing it's job?) Also, If it's rated at 30 amps, 3 P, dose that mean 10 amps per leg times three or 30 amps per leg? Daniel
