2.2.1 Sizing the Grounding Electrode Conductors

AC Side - The size of the AC Grounding Electrode Conductor (GEC –AC) depends on the size of the

largest ungrounded conductor feeding the AC load center. A #8 AWG (8.4 mm

will serve as an AC Grounding Electrode Conductor (GEC –AC) for AC power conductors smaller

than and including #2 AWG (33.6 mm

Table 2-1, AC Grounding Electrode Conductor Sizing

DC Side - To size the DC Grounding Electrode Conductor, you must ﬁ rst determine which one of the

following three methods will be used to connect the DC and AC grounding points in the inverter's

two electrical systems to the common "earth" ground:

Method 1 (see ﬁ gure 2-5): This method uses a separate Grounding Electrode for the DC system

and the AC system. In this method - since there are multiple connections to the DC Grounding

Electrode (GEC – DC) - the size of the DC Grounding Electrode Conductor cannot be smaller than

the 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 the

largest Grounding Electrode Conductor, either AC or DC.
