The first safety knowledge, the safe electricity consumption is less than 36V30 mA, and live working must be carried out by two people! Do a good job of heat preservation! Work attitude, serious and careful! To create a small problem! ! Ask more and learn more if you don't understand. Seek the master! Otherwise it's not safe, no! ! If you don't understand, you must say you don't understand, or there will be a problem! ! High pressure, don't touch it! ! Because you are a beginner, people often ask, what will happen if you encounter problems! You have to say, you have to do it with the master and discuss it together!

General electrician interview will ask some work experience, troubleshooting of some commonly used low-voltage equipment, and the electrician on duty will ask the operation ticket.

You can give full play to your work experience. If you have a short time to get the certificate, you can say that you have been practicing somewhere, and no one in the general unit has checked it.

Read more books on low-voltage practical operation, such as wiring methods, lighting maintenance, micro-switches, etc. High-pressure things can hardly move, so no one takes the exam. When you ask about high-voltage equipment, just say that the company didn't have this kind of thing before, and no one will find it difficult for you to use equipment that you haven't seen before. In addition, the people who took the exam may not know.

If you interview the electrician on duty, you should know some common data of switching operation and transformer.

Now you can get by with a little experience.

good luck
