GEC size

[hhsting]

I have 800A 208V/120V Main distribution service panel with 800A breaker. Grounding electrodes size shown is 300MCM CU one going to steel, one going to metal underground pipe. Is their anything wrong with over sizing GEC 300MCM CU? Code allows it?

The NEC is a minimum standard.

Other than a waste of someone's money, oversize away.
