There seems to be some controversy on the internet wherever I check on how 240 volts is brought into your house. Some sources say that the electrical output of the transformer on the power pole is a 3 wire single phase, or others say it is 2 single phase 120V that have 180 deg of phase difference. I know the transformer has a secondary that is center-tapped, but I could never get the clear answer whether or not its 240V/single phase and (2) 120V/single phase output or (2) 120V with 180 deg of difference between them.
Anyone know for sure?
