What are the two main types of residential wiring circuits?

The correct answer is that the two main types of residential wiring circuits are Branch Circuits and Feeder Circuits.

Branch circuits are the circuits that run from the distribution panel to the outlets, lights, and other devices throughout the home. They are responsible for delivering electricity to the point of use and typically serve a limited area or a specific appliance.

Feeder circuits, on the other hand, carry electrical current from the service panel to sub-panels or other main points of distribution in the home. They are generally larger and designed to handle a greater load since they serve multiple branch circuits.

Understanding this distinction is crucial for anyone involved in electrical work, as it affects how electrical systems are designed, installed, and maintained. Each type of circuit has specific requirements and regulations to ensure safety and efficiency in residential wiring, which is fundamental knowledge in the field of electrical work.
