I'm curious--what's your approach on the GEC?
For residential, it's service entrance panels (all-in-ones with meter base, main breaker, and branch ckt breakers). Mostly 200A, some 100 or 125. Ufer on new construction.
I use #4 copper for either size panel. Use the same to bond the water & gas lines.
I bury the top of the rod 12" below grade and the wire 24". I protect the exposed wire (up the side of the bldg) with sched 80.
What do you do?
