What are the three sections of a switchboard?
Switchboards can come in single panel, assembly panel or structural frame format. They allow incoming electric power to be divided into smaller circuits, depending on requirements. Circuit breakers and overcurrent protection devices should be selected according to the load current.
Why are switch boards made of plastic?
Plastics are poor conductor of electricity and resistant to heat, so they do not allow the electric current to pass through them making them safe to handle. So they are used to make electric switches and plugs.
What are electrical switches made of plastic?
Bakelite is usually used to make switches. it is because it is a thermosetting plastic and so does not melt on heating (electricity generates heat). Also Bakelite is a very durable plastic and a bad conductor of heat as well as electricity, therefore acts like an insulator.

What are the characteristics of a switchboard?
A switchboard may have incoming bus bars or bus duct for the source connection, and also for large circuits fed from the board. A switchboard may include a metering or control compartment separated from the power distribution conductors.
What are bus bars used for on a switchboard?
Buses are mounted within the frame. Horizontal bus bars are used to distribute power to each switchboard section. Vertical bus bars are used to distribute power via overcurrent devices to the load devices. Bus bars are made of tin-finished aluminum or silver-finished copper.
What are the components of a switchboard operator?
Operator components are mounted on the front side of the switchboard. This includes overcurrent protective devices, such as circuit breakers and disconnect switches. These devices are mounted to the bus bars using straps connected to the line side of the devices.
