this is the scenerio
I am bldg a 400A Service using a 320 Metercan, 3"emt riser w/3-500mcm,1-350mcm service conductors. Load side of metercan i am running 2-2" emt conduits with 3-3/0 & 1-2/0 in each conduit to two 200a disconnects. My question is without a gutter ( which you could have a grounding bar)how would you run the grounds to bldg. steel and water pipe from each disconnect. I would have to have a #2 to bldg. steel and a #2 to water pipe from each disconnect along with a #6 to ground rod from each disconnect. I was trying to not have to run separate conductors twice.
