What is the typical voltage used by North American utilities for end users?

In North America, the standard voltage supplied to residential end users is primarily 120 volts. This voltage level is part of a typical electrical service configuration that provides a reliable and safe means of powering everyday household appliances and devices. The 120-volt supply is commonly used for most light fixtures and standard electrical outlets, making it the most familiar voltage level for consumers in typical home and small business settings.

Though other voltage levels, such as 240 volts, are also present in electrical systems (mainly for larger appliances like dryers and ovens), they are not the standard voltage for general household use. In contrast, 480 and 600 volts are generally used for industrial applications rather than residential end users. Thus, 120 volts represents the most common voltage configuration for end users in North America.
