In my new condo at the breaker box I note that Neutral and Ground wires from
the house side are connected to the SAME bus. Why is this? Why not have just
one of these at the controlled device? I'm assuming that this is a kind of

The neutral is designed to carry current. The ground keeps the chassis
at zero potential.

Because there will be some resistance in the wiring, the neutral at the
appliance (or whatever) won't be at zero potential -- it will be at IxR.
This will normally be very low, but it's not zero.
