WebAug 11, 2024 · Sizing the GEC is correlated to the size of the ungrounded (current carrying) conductors. The larger the ungrounded conductors, the larger the GEC. In the event of a phase-to-ground fault the GEC must be large enough to survive for the power system’s protection to operate and clear the fault. WebJun 19, 2024 · Place the first rod as close to the panel as practically possible. The NEC requires minimum 6' spacing between rods, but check with your local inspector to make sure they don't require greater spacing. Also check to make sure they don't require larger conductor size than the #6 copper allowed by the NEC.
WebThe supply-side bonding jumper must be installed in accordance with 250.102(C). The minimum size must be based on Table 250.66 or the 12.5 percent rule based on the total circular mil area of the largest ungrounded phase conductors connected to the generator. WebThe minimum size GEC permitted to connect a concrete encased electrode is 4 AWG copper. Building steel and metal underground water piping that qualifies as a grounding electrode may require a larger GEC since the GEC to these electrodes is sized based on the size of the service entrance conductors and Table 250.66.
WebA few critical resources that you should use regularly are Tables 250.66, 250.102 (C) (1), and 250.122. These tables help you properly size wiring for the grounding and bonding of your …
