Same thing







No, it's not. It's one phase.







Hi,



It's called bi-phase. aka Edison circuit.







Wrong. It's called "split-phase". ...because that's *exactly* what



it is.







"phase" has a meaning. There's still 2 of them. "split-phase" sounds



right too.







Two-phase is something entirely different (and quite rare).











I think I've heard about that. Are the phases 90 degrees apart?







Yes. From it, any variation or number of phases can be easily



generated (efficiently). It's just a little trig and a transformer.







The fact that there is this different 2 phase system doesn't prevent the



usual one from being 2 phase. That's be like saying you don't have 2



colors of holiday lights if they're just red and green.







Words mean things. The proper term for the Edison connection is



"split-phase". It *is* a single phase that is split by a



center-tapped transformer (center grounded).



But that isn't what you objected to. You objected to someone

saying the two hot legs at the dryer are out of phase by 180 deg

with each other.



Get a life Trader. You were wrong then and you're still wrong. Deal

with it.



That is true as can be seen on a scope.

And when you split something, can you cite

an example where after splitting, you still have just one?



Yes. It's still only one (and it's inverse). Get over your

misconceptions.



I really thought you were an engineer. A "sanitation engineer"

perhaps?

Typical. Don't respond to the specific points that go to the
issue, just start with the usual insults. A sure sign that you've
lost the argument and can't address the points.

Here are some references for you that say exactly what I
and Mark Loyd are saying:

http://en.wikipedia.org/wiki/Split-phase_electric_power

"A split-phase electricity distribution system is a three-wire single-phase distribution system. It is the AC equivalent of the original Edison three-wire direct current system. Its primary advantage is that it saves conductor material over a single-ended single-phase system while only requiring single phase on the supply side of the distribution transformer.[1] The two halves are 180 degrees apart with respect to center point."


Note the last sentence.


Or this app note on power configurations, which shows and
talks in detail about split-phase:



http://www.behlman.com/applications/AC%20basics.pdf

Second diagram down:

"The two legs, represented by Phase A and Phase B are 180
degrees apart. Since they are 180 degrees apart, wiring
them together with their relative polarities will result in...."


THAT is exactly what you objected too. A poster made
reference to the fact that the two hots of a 240V service
differ by 180 degrees in phase. You claimed that they are
not 180 deg different in phase, just "opposites". Which
is like saying the south pole doesn't differ by 180 deg
from the north pole, it's just the "opposite". Any one
with any math, science background knows you're wrong here.

Remember how you made a complete ass of yourself not knowing
how a 4 wire vs 3 wire oven connection worked? Even as two EE's
and an electrician told you that you were wrong. Even as I
said just go look at any electric stove installation manual,
which you refused to do? Well, here you are again.
