Wire size for 200 amp service copper.
250.66(A) says the grounding electrode to a single or multiple rods shall not be required to be larger than a #6 copper wire. But in 250.66 it says for a 2/0 copper service entrance conductor, which you have for the 200 amp service, a #4 copper conductor. For residential I've always used a #4 because inspectors seemed to ask for it.

Over here in my area ., the 200 amp residentails typically use 4/0 alum and some case if have to use copper for 200 amp residentails then use 2/0. but for GEC all copper no alum due that size service typically have brick or cement wall and it will eat up alum conductor if not done right.As we will see in the NEC ampacity chart, copper wires can handle more amps than same-size aluminum wires. That’s because copper has a lower resistivity (1.72 × 10 -8 Ohm×m at 68°F) than aluminum (2.65 × 10 -8 Ohm×m at 68°F). That means that the conductivity of copper is higher than the conductivity of aluminum. Temperature.Minimum Wire Size; For that, you go to an ampacity table. That tells you that for 75 C wire in conduit (the wire may be rated 90 C, for various reasons 75 C is the one you usually need to work with for this), the choices are 3 AWG copper or 1 AWG aluminum or larger. Feeders such as this are almost always done using aluminum due to cost. …If you're interested in paying someone from the comfort of your computer without having to leave home, it's worth exploring how to wire money online.
