4. True or False?
1) The electric energy in the ship's electrical system is produced by electric generators.
2) The MSB is a special rubber structure which contains different equipment and accessories.
3) The front side of the MSB contains only signaling instrumentation.
4) Main switchboards are usually installed in the engine room.
5) The entrance to the MSB room is closed with doors equipped with special devices which can hold the door in the closed position.
6) All the instrumentation and measuring equipment of the MSB allows to enable constant monitoring and supervision of the power plant.
7) Power network supplies electric energy to drive engine room mechanisms and other ship's equipment.
8) Emergency lighting network depends on the main lighting network.

6. Translate the following into English:
– Привет, сегодня на уроке мы проходили главный распределительный щит, и мне кажется, я опять что-то не понял.
– Hello. So, you’ve studied the work of the MSB, haven’t you? What do you know about the MSB?
– Я знаю, что весь электрический ток поступает на главный распределительный щиток, где затем распределяется между потребителями.
– Right you are! And what safety precautions is the MSB arranged with?
– На передней панели расположена измерительная и сигнализационная аппаратура. Все остальное оборудование установлено на задней панели. Однако, все оборудование может включаться с помощью специальных рукояток и переключателей, расположенных на передней панели.
– I quite agree with you. Do you know how the MSB are usually installed?
– Да. Обычно главные распределительные щиты устанавливаются так, чтобы они были окружены проходом, шириной 0.6 - 1 метр.
– I guess you know the topic perfectly. What do you have difficulty with?
– Я не понимаю, почему аварийная осветительная сеть работает независимо от главной осветительной сети.
– That’s simple. Emergency lighting is used to illuminate corridors, life-boat areas, control rooms in case of emergency.
– Спасибо! Наверное, я прослушал это.
– You are welcome!
