What is the typical voltage of residential electrical systems in Oklahoma?

The typical voltage for residential electrical systems in Oklahoma is 120/240 volts. This standard voltage configuration is widely used across the United States for residential properties, providing a combination of a lower voltage (120 volts) for general household appliances and lighting, while enabling 240 volts for larger appliances such as dryers, ovens, and air conditioning systems. This setup allows for efficient energy distribution, meeting the varied needs of residential electrical consumption.

In contrast, the other voltage options do not reflect the common configurations used in homes. For instance, 110/220 volts is an outdated standard, as the more current standard is 120/240 volts. The single voltage of 240 volts alone is typically used in industrial applications rather than residential. Finally, 480 volts is primarily found in commercial or industrial settings, where higher power is necessary for larger machinery or equipment, making it unsuitable for residential usage.
