This question is related to NEC. Please answer if you have sufficient knowledge, i.e. if you are an electrician or contractor.
I live in the state of Maryland. I am having a new house built this month.
I wish to know the approximate location to install a grounding rod for (residential) 200 ampere services near the entry point of the house. I also want to know what the recommended gauge i.e. 8, 10, 12? for this rod.
I also want to know the requirement for Dual (two) 200 ampere service. I want to again know the approximate location to place the grounding rod from the wall of the house and also find the recommended gauge of the rod for this situation.
The reason I want to know this information is to verify that the builder building my house is placing the grounding rod according to code.
If you do not know how to answer my questions but can direct me to someone who might have an answer, that would be appreciated as well.
