225.34 grouping of disconnects

[tortuga]

Here is one for the group
A single family dwelling on a farm has two feeders, a newer feeder that is direct from the service pole.
And a original feeder is from a detached barn that has a ATS, very old, and has no EGC,
Both feeders are normally energized, the one from the barn serves 'critical loads', lights, refrigeration most all 120V loads etc.
The newer feeder just serves HVAC.
The barn gets its power from the same service pole in the yard.
Questions:
Does this 'existing feeder' qualify as an additional feeder under under 225.30(4)?
Do the disconnects for these feeders need to then be 'sufficiently remote' from each-other per 225.34(B)?
Thanks in advance

Yes, the supply from the optional standby system is permitted to be a second feeder to the dwelling and it must be separate from the disconnect that is direct from the service pole. How much separation is needed is a judgement call by the AHJ.
I am a bit surprised the 224.34(B) includes optional stand by systems because there is no requirement in Article 702 for optional standby wiring to be separate from any other wiring system.
