Branch circuits are a fundamental component of electrical systems that are used to distribute power from the main circuit breaker to individual electrical devices, such as outlets, switches, and appliances. These circuits are designed to provide a safe and efficient means of transmitting electrical power to devices, while also protecting them from overloading and other electrical hazards. One key aspect of branch circuits is their capacity to handle a specific amount of electrical current, which is determined by the size of the wire and the rating of the circuit breaker. This capacity is known as the circuit's ampacity, and it must be carefully selected to ensure that it can safely handle the electrical load of the devices connected to it. In addition, branch circuits must be properly grounded to prevent the risk of electrical shock and to protect against electrical fires. Another important aspect of branch circuits is their ability to be installed in a variety of locations and configurations to meet the specific needs of a building or space. For example, branch circuits can be installed in walls, ceilings, and floors to provide power to devices in different areas of a building. They can also be configured in series or parallel to provide different levels of voltage and current to devices. Overall, branch circuits play a critical role in the safe and efficient distribution of electrical power in buildings and other structures. By providing a reliable and flexible means of transmitting power to devices, they help to ensure that electrical systems operate smoothly and safely.

Branch circuits are electrical circuits that are used to deliver power from the main circuit breaker to individual outlets, appliances, and other electrical devices. They are typically connected to the main circuit breaker or fuse box using a wire that is rated for the amperage of the main circuit breaker. Branch circuits typically have their own circuit breakers, which are used to protect the device or circuit from excessive current flow. The branch circuit breakers also provide a way to shut off power to the device or circuit in the event of a problem. Branch circuits typically consist of a black (hot) wire, a white (neutral) wire, and a green (ground) wire. The black wire carries the current from the main circuit breaker to the device or outlet, while the white and green wires carry the current back to the main circuit breaker.
