ok here id the situatuation a home owner poured a pad for a house with a wrap around porch poured as well. he put a 2 1/2" pvc into the foundation and stubbed up into a wall along with a 1" stub for communication.
he has a 320AMP service at his other building one 200 amp panel and a 200 amp disconnect which will feed new house(2 1/2" pipe runs to here. he didnt allow for the ground rods (i.e. a pipe for the bare #4 outside of poured area)so can i run the ground rod wire with the 4 wires from the disconnect and clamp onto the original service ground rods or is there a code that says it must be its own ground rods at the location of service(plus that dreaded 25 ohms could come into play on a 140' run back to the meter and would have to oversize wire perhaps) i think i might have to tell him that we have to bust up some of his cement to satisfy the grounding requirements for my two supplimentry ground rods.
anybody ever have similar case? any thoughts?
thanks,
