Electrical Control Switchboard

image001

An electric switchboard is a device that directs electricity from one source to another. It is an assembly of panels, each of which contains switches that allow electricity to be redirected. The operator is protected from electrocution by safety switches and fuses.

There can also be controls for the supply of electricity to the switchboard, coming from a generator or bank of electrical generators, especially frequency control of AC power and load sharing controls, plus gauges showing frequency. The amount of power going into a switchboard must always equal to the power going out to the loads.

Inside the switchboard there is a bank of bus bars – generally wide strips of copper to which the switch gear is connected. These act to allow the flow of large currents through the switchboard, and are generally bare and supported by insulators.

Electrical wiring capacity

Electrical wiring in general refers to insulated cables used to carry electricity and associated devices. This article describes general aspects of electrical wiring as used to provide power in buildings and structures, commonly referred to as building wiring. This article is intended to describe common features of electrical wiring that is apply in carrying out safety installations. A wire or cable has a voltage (to neutral) rating, and a maximum conductor surface temperature rating. It does NOT have a capacity rating, since such is dependent upon the installed environment.
