The Voltage Control Guard (VCG1) is different. The VCG1 is electrically installed in parallel to the neutral bus in an electric panel. The device immediately begins working. The VCG1 reduces daily KWH consumption by inductively capturing noise or unusable current on the neutral line and restores it to phase and polarity so the broad band frequency noises are not dragged back into the consuming loads each time the AC power cycles (60 times per second in the U.S.). There are no lights, switches, capacitors, resistors, circuit boards, or other electronic components ? it does not require or draw power.
