What is the standard voltage for most residential electrical systems?

The standard voltage for most residential electrical systems in the United States, including Louisiana, is 120 volts. This voltage is used for the majority of household appliances and lighting fixtures. It is the typical voltage supplied to outlets where consumers plug in their everyday devices, such as televisions, computers, and kitchen appliances.

In addition, while some larger appliances like dryers or ovens may operate on 240 volts, residential systems largely rely on 120 volts for standard operations. It is essential for a safe and efficient electrical setup in homes, as this standard ensures compatibility with a wide range of consumer products designed to operate at this voltage level.
