Abstract:
1. A GFCI compatible system for reducing common mode noise comprising: a hot line having a first end connectable to a GFCI protected hot node and a second end connectable to a common mode noise (CMN) sensitive device hot line; a neutral line having a first end connectable to a GFCI protected neutral node and a second end connectable to a CMN sensitive device neutral line; a ground line having a first end connectable to an electrical ground and a second end connectable to a CMN sensitive device ground line; a high pass filter connected between said neutral line and said ground line; a hot line relay contact operable to open and close; a neutral line relay contact operable to open and close; a hot line relay capable of opening and closing said hot line relay contact; and a neutral line power relay capable of opening and closing said neutral line relay contact, wherein said neutral line relay is capable of opening said neutral line relay contact when said hot line relay contact is open, further wherein said hot line relay is capable of closing said hot line relay contact when said neutral line relay contact is closed.
