What is the typical voltage for lighting circuits in residential wiring?

• A. 240 volts
• B. 120 volts
• C. 277 volts
• D. 480 volts

Answer: (B)

In residential wiring, the typical voltage for lighting circuits is 120 volts. This standard voltage is widely used for general lighting and receptacles in homes, making it suitable for most household light fixtures and small appliances. The use of 120 volts is designed for safety and efficiency in residential environments, allowing for a balance between energy consumption and the capability to power standard lighting devices effectively. The other voltage levels mentioned, such as 240 volts, are typically used for larger appliances like dryers and ovens, which require more power to operate. Voltages like 277 volts and 480 volts are generally found in commercial and industrial applications, where higher power demands exist, and are not suitable for residential environments due to safety standards and the types of equipment being used.
