thanks guys ,
it was the aesthetics trying to conceal the #4bare from sub-pnl(no meter fed from 200 A disconect other half of 320 service from existing garage)to ground rods drilled through cement.
which would be at the front door of the house so i was wondering if using the conduits back, would be legal and meet the ground rod requirement for seperate building.
since i already have the bond from 200 A disconnect (4-wire) anyway a second would be redundit and close impedance truly would not serve its purpose, because of vault in house(20') i drilled around the corner(side) and hit first ground rod and drilled thugh studs to get to second ground rod minimizing bare copper showing. mission accomplished.
thanks again,
