An electrical load center, also known as a circuit breaker panel or distribution board, is a central point where incoming electrical power is divided and distributed to multiple circuits within a building. It typically contains circuit breakers or fuses to protect the circuits from overloading and short circuits.
The primary distribution center provides overcurrent protection and switching control for load feeder circuits used to distribute electrical power to various loads within a facility or system.
The term used to designate the point in an electrical circuit where electrical work is done is "load." The load is the component of the circuit that consumes electrical energy and converts it into another form of energy, such as light or heat.
A common type of circuit breaker used in a load center is a miniature circuit breaker (MCB) or a molded case circuit breaker (MCCB). These circuit breakers protect the electrical system from overload and short circuits by interrupting the flow of current when necessary. They come in various sizes and ratings to suit different applications within the load center.
The electrical load of a cinema can vary depending on the size of the theater, the number of screens, the equipment used, and the lighting systems. On average, a cinema's electrical load can range from 200-600 kilowatts per screen.
In the 2008 NEC code book, a load center is defined as a single piece of equipment that consists of buses or fixed bars and devices for the purpose of distributing electrical power and dividing circuits within a building. It is designed to house overcurrent devices such as circuit breakers and fuses.
