ELECTRICITY in the USA - AC Current

In a TRANSFORMER 2 COILS allow the transfer of Energy from the POWER LINES to the HOUSE.

IN this we have 2 COILS with 2 HOTS and a NEUTRAL where the NEUTRAL is connecting to both.

This gives us 2 HOT 120v lines. and 1 Neutral. YET they BOTH are CONNECTED TO THE SAME COIL..

WHAT MAKES 1 HOT, and 1 NEUTRAL, WHAT ACTUAL MECHANISM MAKES the ELECTRICTY FLOW out of the HOT LINE, IS it the LOCATION in the FIELD (center vs top or end)11-5-2020 2-58-54 PM.jpg

HOW IS CONNECTED LINE a HOT, and 1 a NEUTRAL , if

It is all relative.

Lets call one HOT line AC1 and the other AC2. The middle connection we call CENTER.
Current through the winding flows from AC1 to AC2 on one half of the cycle and then reverses on the other half, from AC2 to AC1.

The CENTER connection goes along for the ride. You could connect it to 1000V and it makes no difference.
It is common practice to connect the CENTER connection EARTH.

What's with all of the yelling??

Neutral is treated as ground because the utility company grounds the center tap.

ok so in any transformer a hot and neutral comes out (not grounded) which both ends are part of the same wind or coil, so they are the same piece of wire.

yet 1 end it HOT, the other is not. Don't you want to understand why?

by the way the GROUND is for discharge and electrical strikes and not necessary to work.

The Neutral is a current carrying wire just like Hot. It's a name to signify it may have load current characteristics modified by current flows in other current carrying wires called Hot.

Neutrals are commonly associated with secondaries because almost every mains feed originated from a HV transformer's LV secondary.

There is also a case where a transformer secondary conductor is arbitrarily made or called the neutral.
This commonly occurs in industrial equipment where a high voltage supply is used and a 1ph transformer is used to create a 120v AC supply for control circuitry etc.
In this case either one of the secondary terminals can be selected as the neutral and is achieved by connecting this terminal to the system supply ground.
The two conductors that originate from this point are then system neutral and Earth ground.

I do understand why.

Neutral and hot are just labels for the voltage terminals.
You can call them Tom and Jerry if you like.
They have nothing to do with the voltage generated by the transformer or between those terminals.

Note that voltage is always referenced between two terminals.
Labeling one terminal as Hot has no meaning unless it is stated what it's referenced to (in this case Neutral).
