OK, I know what a phase is (roughly). What I am trying to understand
is how power is distributed to a house.
I see a single wire on top of the pole outside my house that runs to
the transformer. The transformer is grounded. Two wires, we got a
circuit ! It appears that the transformer takes whatever is on the
hot wire and supplies a tree wire feed for my house. I assume these
are 120hot, 120hot, and a neutral ?
Are these two phases of 120v power ? Is the transformer just a center
tap type of situation ? Is the neutral that feeds my house bonded to
the ground wire at the transformer ?
Thanks for any insight. FWIW, I am not trying to do my own tap off
the power line, just curious.
