120v240v what does it mean?
In North America it is the standard electrical service connection voltages. Usually a pole mounted transformer supplies this voltage. In newer subdivisions the trend is turning to pad mount transformers which allows the primary voltage lines to be underground. Looking at the transformer you will see three insulator bushings. The first and third bushing are the working voltage (house connections 240 volts). The middle bushing is a center tap. This gives a voltage of (bushing left to center 120 volts) and (bushing center to bushing right 120 volts) These are the the three wires that come into a house for its 120/240 volt service.
