Hi,
I have installed a 200 amp service entrance. I am in the process of attaching it to the grounding rod. What size cable should I use? I was told that a size 8 wire is ok, as long as it is protected. However, I was also told that I should go with a size 4. Can I use the protected 8 or am I better off going with the 4? Are there any advantages of using one over the other? Thanks for your time,

on the houses we build the electricians use #4 bare wire.

Hey Kate is right. Your inspector is the final say and some are picky. For 200 amp you should be using 3/0 copper and you would need #4 ground with that according to the NEC. But you didn't say what size your service conductors are. Ask your Inspector and get it right the first time.

What is code for your area ?
Better ask your AHJ, because if they come for the final and it is NOT how they want, you gotta do it over.
Better to ask and do it how they want the 1st time.
