2.6. – Hello. Today during the lesson we were explained the types of circuits, and I guess I haven’t caught everything.
– A series circuit is a kind of circuit where there are two or more resistances that are connected in one continuous path so that the current passes in turn from one to another. As I have understood, it is convenient to use this circuit wherever a constant voltage power supply system is needed.
– I see. Does it mean that a parallel circuit in which the current has two or more paths in which it may flow is convenient for using in a house wiring?
– Thank you. Now it is much clearer.

3.6. – Hello, today at the lesson we have been studying the MSB, and I guess I haven’t understood something.
– I know that all the electriс current comes to the main switchboard, where later is distributed between the consumers.
– The front side of the MSB contains signalling and measuring instrumentation. All the other equipment is mounted in the back side. However, all the equipment can be controlled and regulated by means of special handles and switches which are located in the front side.
– Yes. Usually the USB are located so that they could be surrounded by passages about 0.6 - 1m wide.
– I can’t get it, why the emergency lighting network is independent on the main lighting network.
– Thank you! I must have missed it.
