so came across this. A 60hz harmonic line filter. what does it do? filters ac ? how? only allows 60hz to pass thru the filter. basically a giant low frequency sub sub woofer filter in design. does it work? seems to. trannies don't buzz anymore and motorized devices don't squeal at high rpms , so yes it works. this one is a 14 amp times 3 440V capable one...it can do three phase. but easy to adapt to single phase 120 or two 120 phases off of 220/240. main thing to remember is to wire as a sub panel....you will need to add a ground bar and a floating neutral bar. and put it in a box so your cat doesn't get electrocuted.
duh...welcome to the new forum...pic wont up load..
