I just noticed that all the residential transformers on the poles on my street only have one wire feeding them. There are three wires on top of the pole.
One wire in, and three wires out to the triplex feeding my house. There are no other visible connections on the transformer.
Heck, the next street over only has ONE wire at the top of the pole...
I thought the three wires on the pole corresponded to each leg on my breaker panel, and a ground wire.
How is the transformer creating two 110V legs and a ground from one feed wire? This just goes against everything I learned in school about electricity.
