Page 31© 2009 Magnum Energy Inc.Installation2.6.1 Sizing the Grounding Electrode ConductorsAC Side - The size of the AC Grounding Electrode Conductor (GEC –AC) depends on the size ofthe largest ungrounded conductor feeding the AC load center. One #8 AWG (8.4 mm2) copperconductor will serve as an AC Grounding Electrode Conductor (GEC –AC) for AC power conductorssmaller than and including #2 AWG (33.6 mm2) copper. See Table 2-4 for additional values.Table 2-4, AC Grounding Electrode Conductor SizingSize of LargestUngrounded ConductorMinimum Size of GroundingElectrode Conductor#2 AWG or smaller #8 AWG (8.4 mm2)#1 to #1/0 AWG #6 AWG (13.3 mm2)#2/0 or #3/0 AWG #4 AWG (21.1 mm2)Over #3/0 AWGthrough 350 kcmil #2 AWG (33.6 mm2)DC Side - To size the DC Grounding Electrode Conductor, you must first determine which one of thefollowing three methods will be used to connect the DC and AC grounding points in the inverter’stwo electrical systems to the common “earth” ground:Method 1 (see figure 2-17): This method uses a separate Grounding Electrode for the DC systemand the AC system. In this method - since there are multiple connections to the DC GroundingElectrode (GEC – DC) - the size of the DC Grounding Electrode Conductor cannot be smaller thanthe largest conductor in the DC system (usually the battery-to-inverter cable).The DC Grounding Electrode (GE – DC) must be bonded to the AC Grounding Electrode (GE – AC)to make a grounding electrode system; this bonding conductor (BC) cannot be smaller than thelargest Grounding Electrode Conductor, either AC or DC.A CD C S e rviceP a n e lA C S e rviceP a n e lD C E lec tric al S y s temA C E lec tric al S y s temN eutr alPositiveN egativeD CG roundingS y s temN e g a tiveS B JG CG E C -A CE G C - A CAC G r ound D C G round S B JE G C - D CG CN e u tra lH otG E C -D CG E G EG B B G B BGrounding Electrode(D C side dedicated)Grounding Electrode(AC side dedicated )M S -A E S e rie s In ve rte r/C h a rg e rB CFigure 2-17, Multiple Connections to DC Ground Rod (Method 1)
