Default How does the typical mains power connect in the USA anyway?

Here is a picture of the incoming wires to my main circuit breaker:

If we follow those three wires *back* to the nearest transformer, what
do they look like (in terms of phase relationship to each other)?

If we follow those three wires *forward* to the first circuit breaker,
what do they look like (in terms of connection to the literal earth of
the ground)?

Note: This question is an offshoot of a 220v dryer question; but this
question is asked to get to the root of *what* it is that is entering
the house in the first place.

Hi,
How is your house electric system grounded? I still think your dryer is
not grounded well. Measure between the dryer chassis(body) and ground
point in Ohm scale on your meter. Do you read zero Ohm or fraction of Ohm?
Also you should read zero Ohm between gnd(dryer body) and neutral on
your dryer.

If it is all OK, some one else mentioned heating element sagging when
hot rubbing on the dryer chassis not enough to kick the breaker but give
spark and shock specially when hand is moist(doing washing)

I think this thread is coming to an end.
