Hi Ed, Chris, all,

I believe in my area, 10 kVA is about the smallest pole transformer
that is used for even a single residential customer, and usually it's
15 kVA. The transformer serving my home (it's a pad mounted green
box since all of the lines in my neighborhood are underground) is a
50 kVA unit but it serves at least 3 other homes, I believe.
