TGIF!
I have a unique (to me) electrical service upgrade question. I am currently installing a stand-by generator at a farm where we are also upgrading the existing 60 amp Edison Fuse Panel to a 100 amp main lug panel. It's a small farm house and this new service will be fed from a 200amp Main Breaker panel that is fed from the typical Entry Rated xfer switch with a Main breaker. Coming from this the 200 amp Main Breaker panel we will be feeding the farmhouse 100 amp main lug panel. I was planning on running 2-2-2-4 MHF to the home breaker panel from this sub. There is also another future sub-panel that will be fed from this 200 amp Main Breaker to service a milking barn in the spring when we make that upgrade. The Meter Base, Xfer switch and 200 Main Panel are all mounted on a pedestal that is about 60' from the farm house. I'm looking at this as a mobile home feed in a lot of ways and I want to make sure my thinking isn't skewed or that I am over thinking it. A couple of questions come to mind:
1. The ground rod array will be placed at the base of the pedestal and not the home.
2. I'm running the MHF in 2" PVC underground so fill isn't an issue per code.
3. I'm only bonding the xfer switch and not the 200 amp main or the main lug 100 amp main lug home panel.
This is a fairly common setup in our area with Irrigation Pivots and farmsteads. They will feed 2 or 3 small homes from a single 200 amp pedestal mounted panel. I want to make sure this isn't an outdated methodology and I don't have a lot of experience personally installing with this method. We mostly do the common 200 amp service upgrade and other electrical farm related work. Thank you for any thoughts you can provide!
