A GFCI compatible system and method for activating relay controlled lines having a filter circuit between neutral and ground is described herein. Specifically the disclosure teaches a GFCI compatible system for reducing CMN. A CMN Suppressor can comprise a hot line, a neutral line, and a ground line. The first ends of the hot line, the neutral line, and the ground line can be connected to a GFCI protected hot node, a GFCI protected neutral node, and an electrical ground. The second ends of the hotline, the neutral line, and the ground line can be connected to a CMN sensitive device hot line, a CMN sensitive device neutral line, and a CMN sensitive device ground line. The system can further comprise a high pass filter, a hot line relay contact, a neutral line relay contact, a hot line relay, and a neutral line power relay.

A transient voltage surge suppressor is provided to protect equipment with voltage sensitive electronics, such as office equipment, from surges or transients in the multi-phase power distribution network furnishing power. The surge suppressor senses the incoming voltage and electrically disconnects the neutral leads and hot leads of the power network from the neutral lead and hot lead of the office equipment if a voltage surge above an established level is sensed. The suppressor also disconnects its output when a ground connection in the multi-phase power network is disconnected to protect the equipment against excessive voltages. In this situation, the suppressor circuit protects its internal components from damage and possible fire hazard when its output is disabled, so that the suppressor can resume its function when conditions in the power distribution network return to a satisfactory state.

An improved power filter circuit is disclosed. The improvement concern providing a clamping device between a ground lead and a terminal of a safety circuit such that when the power filter has its hot and neutral leads properly connected to hot and neutral leads of a utility circuit, a switch of the safety circuit connects the clamping device to be between ground and neutral leads of the power filter circuit, but when the hot and neutral leads of a utility circuit are reversed, the switch of the safety circuit connects the safety circuit directly between the neutral and hot leads of the power filter circuit, thereby creating an indicator, such as a red light, that the hot and neutral leads are reversed, yet the clamping device is now not connected between the neutral and ground leads of the power filter circuit. Accordingly, the clamping device connected between the ground and neutral leads may be rated during normal operations at a lower value, e.g., 20 volts, to protect against possible surges of a lower voltage level between the ground and neutral leads. Further, a capacitor is connected between the ground and neutral leads during normal operations of the power filter circuit. The value of the capacitor is large so as to provide substantially unlimited filtration between neutral and ground during normal connection of the power filter circuit to a power utility outlet. Such filtration protects computers and computerized equipment against malfunction.
