Is the electrician's certificate high voltage or low voltage good?

It is recommended to take the low-voltage electrician test first. Low-voltage electrician is mainly responsible for the installation, debugging, operation, maintenance, overhaul, transformation and test of low-voltage electrical equipment below 1000 volts. The working range is wider than that of high-voltage electrician. You can take the low-voltage electrician certificate first, and then consider the high-voltage electrician certificate. The training content of high-voltage electricians is based on low-voltage electricians, so it is more convenient to test low-voltage electricians first and then high-voltage electrical unions.

The examination process of low-voltage electrician is divided into theoretical examination and practical examination. There are 100 questions in the theoretical examination, with a total score of 100, 80 passing, and two make-up exams. Usually, I practice more.

There are four questions in the practical test, mainly about the identification of safety appliances (precautions for the use of various electric meters and safety appliances), safe operation technology (wiring of different circuits), identification of safety signs, investigation of hidden dangers, and first aid for electric shock. Similarly, the total score of 100, 80 is qualified, and there are two make-up exams.

1. Low-voltage electrician certificate has a wider scope of application, which can help us find a better job. Whether some companies are recruiting jobs, factory maintenance electricians, engineering electricians, or their own homes, they may encounter some electricity problems in the future, and they all need low-voltage electrician certificates.

Although high pressure and low pressure are very dangerous to our human body. However, if all the accidents are caused by operational errors, compared with high pressure, low pressure will do less harm to human body.
