The typical voltage for a residential socket meter is 120 V. This standard voltage is used in most homes to power various appliances and devices. The voltage rating of 120 V provides a balance of safety and efficiency for everyday electrical use in residential settings.

The confusion with other options might stem from the vicinity of voltages used in different applications. For example, while 240 V is commonly used for larger appliances such as dryers and ovens, it is not the standard voltage for typical socket outlets. The 110 V is an older reference that is often used interchangeably with 120 V, but it is not the current standard for residential sockets. A voltage rating of 300 V is far beyond the standard for typical home use and would be considered industrial or specialized equipment, thus making it unsuitable for residential electrical systems.
