Well, you arent going to find a clear explanation here either.

Is he asking?, "is it single phase in a residence or split phase?"

AK post #5 is a simple clear explanation of what is going on be careful because this question can open a big can of worms for example in the post Battle of the phases http://forums.mikeholt.com/showthread.php?t=96251&highlight=battle+phases Take note that it has been closed by the moderators so dont feel bad if you cant give a clear explanation you are not alone. It is most common in single phase and 3 phase delta systems.AKwiring said:

Fair warning, no battle of the phase here. Stick with the OPs question or open a new thread. Thanks.

Almost as simple as two 1.5 volt batteries in series.AKwiring said:
They add up to 3 volts yet are independant 1.5 volt charges.
It is the same in a single phase house service where the 240 volt winding is tapped in the middle and grounded for a number of reasons.
Which is very subjective so I will keep it simple as the op and Bob both request and not go into that other than to say the 2-120v segments are additive to 240v.

I 3rd that(let me add), Voltage add in parallel(often forgot), resistance in series(who remebers that...), the picture did kinda say it all(cheat) ...

Nominal voltage? (215, 220, 225, 230? or Actual voltage 240? :wink:
mivey said:I'll 4th that (#2). Plus the picture from #5.
This is too easy. Would you like to clarify your question so we can have more fun?
But not too much fun at the OPs expense. Remember, my guess is he's relatively new to the trade, so a question like this isn't going to be old hat to him.
If you guys like pictures, how 'bout this one?

Let's get this on the way to 847...
Could you explain this further?

Point Taken:
Did I say that, I did and its totally wrong, who's on first!
I forgot the simple line diagram and the correct aspects of using Voltage and Resistance when sovling any quantive measure of a series or a parallel circuit.
Here's a link to the correct aspect of Voltage in a parellel circuit

AKwiring said:
Sometimes people think of AC power like a car battery with a positive and a negative and understand that current flow is from the "hot" to "ground" (we know better).
It appears to to explain the 120 volt circuits in a typical house.
Then we have this problem to explain how and where 240 comes from and where it goes now that the ground is not present.
Is this kinda of what you are asking AK?

"Appears" is correct. The car "ground" is not really so much a ground as it is a return conductor. It is usually not tied to the "earth ground".jrannis said:
The 120 has two conductors, one of which is tied to ground (what we call "earth") at some point. We usually call the grounded conductor the neutral.
The single phase 240 normally does not have either of its two conductors tied to the earth.
