Neutral should normally be a non current carrying conductor but it should be sized to carry momentary current caused be short circuits in the equipment All of the neutrals in a system should connect at a central point and that point should be connected to the system ground The goal is to minimize the current through the ground conductor Circulating ground current is a source of electrical noise normally associated with unbalanced voltages or unbalanced loads Capacitive or inductive coupling between power lines and the neutral or ground conductors is another noise source Currents that flow through capacitive paths or from a magnetic field tend to change rapidly and produce high frequency interference called RFI radio frequency interference Good grounding is also important to minimize the effects of large voltage spikes that can create significant current flow in the ground conductors The source of these voltages can be lightning striking the power lines switching of large power loads and others A balanced three phase four wire system with a system ground as shown in Figure D 1 can minimize noise problems normally associated with grounding AC power and motor leads should be as short as possible and enclosed in conduit or shielded cable should be used Power wires and Motor leads should never be in the same conduit Figure D 1 Control Enclosure Note Wiring shown for clarity of grounding method only Not representative of actual t
