Get PowerNet of each connected node

[galford13x]

I would like to know how I would obtain the Power Objects of the connecting nodes.  For example:
P = PowerConduit
N = My Node

                  P3
                  P3
P1 P1 P1 P1 N0 P4 P4 P4 P4
                  P2
                  P2

There could be 4 different networks connected to a hub @N.  Is there a way to distinguish between P1, P2, P3, P4?
This assumes there is no connection between P1, P2, P3, and P4 except @N.
