I have to get power from an established 320A service on a garage that’s 275’ away from a new construction residence.
House load center will be 200 A 120/240V single phase.
Calculated load ( with current info from owner) is 130 amps.
It will be underground. I’m planning on using a single set of 250 MCM AL for the feeders.
300 MCM would give me a bit more leeway as far a VD if they choose to add say a EV charger down the road.
At this point they see no load addition in the near future.( Heard that before)
Would you just go with the 250 that’s readily available or opt for the 300 that’s a special order at this point.
Also, 250 will fit all the lugs that I will be terminating on ( disco, load center) 300 will need reducers to fit.
It’s direct burial that takes a very wayward path from A to B because of the terrain, conduit isn’t a practical option.
Any suggestions welcome.
