When preforming a load calculation on a Duplex, do i need to consider it as one, or would I consider each "Dwelling" seperately? Would I do two seperate calculations or just one? Im thinking just one since there is only one feeder coming into the Two-Family dwelling, and then it is split at the 2 gang meter base. Thanks for help and very nice forum. Doesnt look as busy as I thought, but nice.

Without knowing the size or age of the place, I'll guess 200A to the meters then 100A to each unit, it's a popular setup.

For only two units calculate them each separately and combine the loads for the service.
For instance, if you get over 100 amps for each you would need a double 150 or 200 with a 320 or 400 amp service entrance.
