Ground Rod
So, i've completed an installation of a 100 amp subpanel in a detatached garage.. and i'm trying to sort out the ground rods... My question is how many do i need? I can not seem to locate the requirement for the number of rods in the 2011 NEC? 1 or 2? or the wire size...
thanks

The number of ground rods needed is not specified in the code, only the requirement for a low-impedance path to ground. The means needed to meet that requirement is a local decision based on the conductivity of the soils in your area.
Ask your inspector.
