I am considering bidding on a new house. The GC told me that the electrical inspector told him that the service require two ground rods and the wire between them had to be buried 24?.

Has anyone come across this?
 
Is it a local code. I know a couple of towns require 2 rods. But never heard of the 24" depth.

I would talk directly to the electrical inspector. Ask to see the code he is referring too.
 
If you are using ground rods for your grounding electrode, then for all practical purposes, 250.56 requires that you use two.
There is no burial depth requirement in the NEC for the grounding electrode conductor.
Also in new construction with rebar in the footing there should be no need for ground rods...the rebar is the grounding electrode and you are required to use it if it is there. This means you (electrical contractor) have to be on the job when the footing is ready to be poured.

I permit the GC to leave a rerod exposed near the service. This saves the EC a trip.
 
I agree with Don. For a new house you're likely required to use a CEE. If so, forget the ground rods altogether since they won't be necessary.

Depending on the GC, good luck in being there before they pour! If it's a GC you normally work with, then this shouldn't be a problem.

Here they make that the GCs problem. It is the GCs reponsability to hire an EC before the pour is made.
