MCB
A miniature circuit breaker (MCB) automatically switches off electrical circuit during an abnormal condition of the network means in overload condition as well as faulty condition. ... MCB is much more sensitive to over current than fuse. Handling an MCB is electrically safer than a fuse.
Switch
A switch is a piece of a physical circuitry component that governs the signal flow. Having a switch or toggle switch allows a connection to be opened or closed. When opened, the switch allows a signal or power to flow through the connection. When closed, the switch stops the flow and breaks the circuit connection.
Holder
A bulb holder is a device that holds a bulb. The bulb holder is where the bulb fits. The image below shows a bulb holder from a ceiling light. The bulb fits into the bulb holder, the bulb holder 'holds' the bulb. The bulb holder contains the electrical connection from the supply to the bulb.
Conductor
A conductor is a material which electricity, heat or sound can flow through. An electrical conductor conducts electricity. The ability to conduct electricity is called electrical conductivity. Most metals, like iron and copper, are electrical conductors. These metals are used to make wires to carry electric current.
Plug
AC power plugs and sockets connect electric equipment to the alternating current power supply in buildings and at other sites. Electrical plugs and sockets differ from one another in voltage and current rating, shape, size, and connector type. Different standard systems of plugs and sockets are used around the world.
