A distribution board (also known as panelboard, circuit breaker panel, breaker panel, electric panel, fuse box or DB box) is a component of an electricity supply system that divides an electrical power feed into subsidiary circuits while providing a protective fuse or circuit breaker for each circuit in a common enclosure.
A motor control center (MCC) is an assembly to control some or all electric motors in a central location. It consists of multiple enclosed sections having a common power bus and with each section containing a combination starter, which in turn consists of motor starter , fuses or circuit breaker , and power disconnect .

Load management, also known as demand-side management (DSM), is the process of balancing the supply of electricity on the network with the electrical load by adjusting or controlling the load rather than the power station output.
There may also be instruments and controls for the supply of electricity to the switchboard. For example, a switchboard for a bank of electrical generators, especially frequency would have control of AC power and load sharing, and instruments for frequency, voltage, current, and energy, with perhaps a synchroscope. A main switchboard is a large ...
The PDC housing contains a transformer, which steps down the incoming power to a lower voltage to feed other plant loads such as motor control centers (MCC's). Feeder breakers for these loads will be located on the PDC. PDC's will often contain additional protective relays, monitoring equipment, fuses, terminal points, etc...
Layout details and construction of electrical rooms will be controlled by local building code and electrical code regulations. Requirements for an electrical room relate to fire safety and electrical hazards.
An electrical load is an electrical component or portion of a circuit that consumes (active) electric power, [1] [2] such as electrical appliances and lights inside ...
Alternatively, disparate sources can be combined to serve a common load if some external power converter, such as a rotating machine or a direct current converter system is interposed. Electricity is consumed as soon as it is produced. It is transmitted at a very high speed, close to the speed of light.
