The starting point of weak current is relatively high, but it is very simple to learn, mainly the problem of integrated wiring. The original factory is responsible for the equipment, so there is no need to study it. The starting point of high voltage is relatively low, but the coverage is relatively wide, and there are many problems involved, so it is difficult to go deep, such as secondary circuit and tertiary circuit. Personally, I think it is better to learn weak electricity, because there are more people who know strong electricity now, and relatively few people know weak electricity. Moreover, the requirements for fire prevention are getting stricter and stricter, and the requirements for energy saving and intelligence are getting higher and higher. The prospects of fire-fighting weak current and intelligent weak current are getting better and better. If it is really weak, the basic strong electricity will naturally.
