Ed,
We recently upgraded to a Phase Perfect Enterprise from a Kay Rotary. ?Wired in a disconnect in front of the PP, and installed a 3 Phase Panel
for 4 other pieces of equipment, with room for expansion. ?My hearing is still pretty good ( I still chase elk with a bow, and am 67).
and find the PP 'noise' to be a non issue. ?I do wear ear plugs when running equipment which helps. ?We also ordered direct from PP,
the cost was competitive, and the folks there were fantastic to work with. ?The big plus, is the voltage is very even on all 3 legs...
