How are power and lighting circuits differentiated in residential wiring?

• A. Power circuits are for lighting and lighting circuits are for power
• B. Power circuits are for receptacles and larger loads, lighting circuits are for fixtures
• C. Power circuits are always 15-amp and lighting circuits are 20-amp
• D. There is no differentiation in residential wiring

Answer: (B)

In residential wiring, power and lighting circuits serve distinct purposes that cater to the different needs of electrical loads. Power circuits are specifically designed to support receptacles and larger appliances that require a greater amount of voltage and amperage to function efficiently, such as refrigerators, air conditioners, and other heavy-duty electrical devices. This differentiation ensures that these circuits are capable of handling the higher loads without overloading the system. Conversely, lighting circuits are intended for powering light fixtures and typically operate at a lower demand level. These circuits are set up to provide sufficient electricity for overhead lights, sconces, and other types of lighting that don’t require as much power, thus ensuring safe and efficient operation without risking tripping the circuit breaker. Understanding this distinction is essential for proper electrical planning and installation in residential settings, which helps maintain safety standards and ensures that the electrical system works effectively without issues stemming from overloading.
