"220 Volt" refers to an electrical voltage level commonly used in many countries for residential and commercial power supply. It is higher than the standard 120 volts used in places like the United States, allowing for more efficient energy transmission and the ability to power larger appliances, such as air conditioners and electric ovens. In regions that utilize 220 volts, electrical systems are designed to handle this voltage safely. This includes specific wiring, circuit breakers, and outlets that accommodate the higher voltage. Countries like Europe and Australia predominantly use 220 volts, while others may have different standards.
