Hi Myles,

It is like any parallel circuit. At one point they are all together,
but they all fly off in different directions and different lengths to
reach the various outlets and switches throughout your apartment.

By code, all of your power demand is spread out and BALANCED so that
no one breaker/fuse is carrying the whole load. This means that your
clothes dryere is not on the same circuit as the oven. They each have
their own wires that goes back to the breaker panel, and each has
their own breaker. Likewise, each room's outlets and lights goes on
its own wire back to its own breaker at the breaker panel. Sometimes
it might be two rooms sharing the same path. This is where you get
into trouble by injecting RF from your shack into the light dimmer in
the bath room.
