Wiring, wiring and other work seems simple, in fact, it requires a lot of basic electrician knowledge, and if there is no electrician certificate, then your operation and the unit that employs you are illegal. Therefore, in order to have a professional technical skill to make a living, I suggest you take the electrician qualification certificate, which is briefly introduced as follows:

Electrician qualification certificate is also called vocational qualification certificate or electrician grade certificate. The classification includes five levels: primary (level 5), intermediate (level 4), advanced (level 3), technician (level 2) and senior technician (1 level). It is the main basis for employers to recruit workers, and it is also an effective certificate for notarizing the skill level of overseas employment and foreign labor cooperation personnel.

The issuance of electrician qualification certificate is: the human resources and social security department of the local government (formerly known as the Labor Bureau) holds a training course, and the certificate is issued after the training course passes the examination. Although this card is issued locally, it is common all over the country. The study time is about 3 months. With this certificate, your employment scope will be large, your income will be relatively stable, and it will even have an important impact on your life. Do not hesitate.
