+<blockquote>In our area we are allowed to dig a trench 20' long, install some 3" concrete dobbies to hold the wire off the dirt, lay a bare ground wire sized for the system [minimum #4 copper for concrete-encased electrode], get an inspection, then pour concrete over the ground wire. the concrete must surround the wire 3", bottom, sides and top, so you have at least a 6" x 6" x 20' long concrete buried 18" deep. (it takes about 10 to 12 dobbies to keep the wire off the ground)<cite>[[http://www.electriciantalk.com/f2/ufer-ground-1038/#post152255 |www.electriciantalk.com]]</cite></blockquote>
