For a 1600-amp service, the NEC (National Electrical Code) typically requires a grounding electrode conductor sized at 3/0 AWG copper or 250 kcmil aluminum at minimum, per NEC Table 250.66. However, the specific grounding conductor size may vary based on the service entrance equipment, local utility requirements, and whether additional bonding or grounding electrode systems are required. Always consult your local AHJ and utility for final specifications.
