I currently have the old non-grounded 100 amp panel and I am upgrading to 200 amp, so naturally the new panel has to be grounded.

My first question is: What is the maximum distance that the ground rod can be located from the service panel?

Due to the concrete below the panel and layout of the house, the only convenient place to put the ground rod is 20 feet away.

My second question: Due I need to run bare copper wire to each ground rod (I have heard that it is better to install more than one rod) or can I run an insulted wire and just remove the insulation at the grounding point.

Thanks,

Zack

Are you replacing the panel and meterbase? Is the current meter already grounded? If so, how?

I am replacing the existing panel with an all-in-one panel that the meter mounts on. The current meter I don't beleive is grounded except for the grounding of the neutral out at the pole.

I would suggest you contact your local building inspector to see what he(she) will allow. Going thru the concrete isn't that hard to do if that is what they require. If you do have to run out 20ft, the ground wire will probably have to be in conduit to provide for physical protection.
