Ground Rod
My main panel is grounded at the adjacent cold water pipe.
I understand this is no longer Code compliant but grandfathered in.
IF, I wanted to install a new ground rod...
What are the current requirements?
Copper rod?
How long?
How far away from the house?
How much exposed above the ground?
Guage of wire used to connect to panel?
Insulated or bare?
Many thanks!

The conductor to a ground rod never needs to be larger than #6. It can be bare or insulated.
The rod can be copper clad or galvanized and will be 8' long. It will be flush or below ground.
The distance away from the house needs to be far enough out to clear the footer.

The water service is your main grounding electrode. This should be bonded to the panel at the point of entry to the building. A ground rod is a supplemental grounding electrode. This is why the grounding electrode conductor to the ground rod never needs to be larger than #6 copper while the one to the water service conductor is required to get larger as the service size gets larger. (#6 for 100 amp #4 for 200 amp)

Traditionally 8' x 5/8" copper clad steed ground rod , or bigger .
