In the USA it is single phase (though people call it two phase which is wrong). The transformer is center tapped so you get two 120V legs (240V between the two legs), and the neutral is at the transformer for a Delta system and for a Wye system is it distributed neutral wire.The lines enter the home either overhead or underground.

In the game Number Lines - Phase 2 the aim is to arrange the given number in the net so that the sums of all line to be equal to the given number. The power cells have to be placed in the circles so that all the numbers in the. POWER LINE TOTAL.

Some states require new builds to have underground service.The distribution to the transformer could vary. See here:.EDIT: I used to be a distribution engineer.

Depends a bit on the area, where I am they actually have a couple houses per transformer so most neighbors here have the same phases. Poles carry the high voltage lines, it can be one, two or three phase. Residential power hooks up a single phase transformer to one phase of the high voltage line on the pole, that generates 240V split phase (+/-120 and neutral), the neutral is then grounded.Residential areas will often only have one phase on the street, so all homes are the same phase, main roads and areas with commercial stuff will usually have three phase on the street, commercial buildings getting three phase power and residential buildings getting split phase power from one of those three phases (and what specific phase can vary). On the high side (H side), it is a single phase connected (ex. That phase is 120 degrees out from the other phases (VBC, VCA) when you measure them against each other.On the secondary side (X side), it is still the same single phase (VAB), but at the new voltage (from 12.4kV to 240V). Since there is only one phase available on the secondary side, then you can't really reference it to the other phases (VBC, VCA), so the 120 degrees between the primary waveforms is no longer important.The 180 degrees comes from WHERE you measure it on the secondary side. If you compare X1-N (One of the secondary legs to Neutral) and X2-N (the other secondary leg to Neutral), they are 180 degrees apart because the way you are measuring splits the single phase (240V to two 120V) evenly in half such that you have two waveforms that appear 180 degrees apart.

That is the magic of the center tap. Move the tap and you can split the 240V different ways between the X1-N and X2-N connections.This is often done in substations to regulate voltage (big boy Transformer Tap Changer), and not so much on your pole transformer. Although you can find voltage regulators that do this same thing mounted on poles on the distribution lines. They look a little like your home pole transformer, but bigger and with radiator fins.

Also, the neutral (center tap) is grounded to the Earth, either with a metal stake into the ground, or by attachment to a metal water pipe. Thus, each power line in the house is either at ground potential (approximately) or at 120 VAC with respect to ground.In a 240 V feed (e.g. Far cry 4 download. A dryer outlet), each power line is 120 V from ground, but out of phase, so they are 240 V line-to-line.In a breaker panel, half of the 120 V breakers are fed from one side of the 240 V, and half on the other side. 'Join two devices'. Do you mean connecting low-level signal cables between devices connected to each side of the split-phase or something else?

Their neutral potential should be about the same and their safety ground potential should be the same.Now, you could run into problems with low-level audio signals between any devices where the signal ground is tied to the electrical safety ground at more than one point in the whole system, but the worst things I've experienced have been situations where one device is grounded via something different (e.g. A cable TV shield which was at a volt or so AC with respect to the electrical ground.)(Edit: let me clarify, there should be no safety problem as long as the house is wired correctly and the devices are UL (or similar) listed. Everything you connect between the two should be isolated from the power carrying conductors (line and neutral)).
