Then consult NEC Table 250.122 to find the minimum grounding conductor size. For example, a 100-amp circuit requires 8 AWG copper or 6 AWG aluminum grounding conductor. Always use the size corresponding to your OCPD rating, not the conductor size.
Selecting the correct ground wire size, as outlined in NEC Table 250.66, is paramount for effective grounding. Wire size directly relates to its current-carrying capacity. Just as a larger pipe carries more water, a thicker wire safely conducts more electricity. Using an undersized ground wire risks system failure and potential hazards.
To size a grounding conductor according to the NEC, first identify the rating of the overcurrent protection device (OCPD) protecting the circuit. Then consult NEC Table 250.122 to find the minimum grounding conductor size. For example, a 100-amp circuit requires 8 AWG copper or 6 AWG aluminum grounding conductor.
