110V120V

110V120V refers to a nominal voltage range commonly used in North America for residential and commercial electrical power. This range is generally considered to be between 110 volts and 120 volts alternating current (AC). In many regions, the standard utility voltage is 120 volts, but it can fluctuate slightly and is often referred to more broadly as 110V or 115V.

This voltage is distinct from the higher voltage, typically 208V, 220V, 230V, or 240V, which is used for higher-power appliances such as electric dryers, ovens, or central air conditioning units. Devices designed for 110V120V systems have plug configurations that are incompatible with higher voltage outlets to prevent accidental connection and potential damage or hazards.

The prevalence of 110V120V systems in North America is largely due to historical reasons and established electrical infrastructure. While the exact nominal voltage can vary slightly depending on the utility company and local regulations, the 110V120V designation remains a widely understood standard for many common electrical devices. When purchasing electronics or appliances, it is important to verify their voltage requirements to ensure compatibility with the local electrical supply.
