First, we start by understanding what an electrical panel means; it is sometimes called a load center, distribution board, main switch, or breaker panel. It is a service box that takes electricity into the house and then distributes the electrical current to various circuits in the house. The electrical current, which is distributed in different circuits, is then protected by a circuit breaker / fuse. Each circuit breaker trips on overload, so the electrical panel's job is to regulate the current load in your home and keep your home safe and comfortable.uture wiring needs.
