What is AC - Alternating Current:

AC is the standard form of electrical current supplied by the utility grid and by most fuel-powered generators (diesel or petrol "gensets"). The polarity (and therefore the direction of current) alternates. In the USA, standard voltages for small water pumps are 115V and 230V. In most of the rest of the world, standard voltages for small water pumps are 220-240V. In most of the world, the current frequency is 50 Hz ("Herz", or cycles per minute), while in the US, the current frequency is 60Hz.
