What are the general contents of the electrician certificate exam?

The examination is divided into two parts: theoretical examination and practical examination. The difficulty of the exam depends on which one you specifically declare. If it is an electrician's certificate from the Safety Supervision Bureau, then the focus of the examination should be the theoretical examination.

The examination contents include ohm's law, series-parallel circuit, power accounting, electricity safety, fluorescent lamp working circuit, motor forward and backward rotation, application of electrical instruments, electric shock first aid and so on.

Three kinds of certificates commonly used in electrician certificates are issued by three different departments, and the examination contents are different according to the types of certificates applied for. The general special operation certificate pays attention to safety training, the electrician grade certificate issued by the Human Resources and Social Security Bureau pays attention to basic content, and the network access certificate issued by SERC pays attention to practical operation and application.

There are three kinds of general electrician certificates that need to be used in the operation, which are issued by three different departments respectively.

A, the safety production supervision department issued the "special operation certificate (electrician)";

Two, the Energy Bureau (electricity supervision) issued by the Department of "electrician network operation permit";

Three, human resources and social security (labor) department issued the "electrician skill level certificate". The first two types need to be reviewed regularly (once every three years). If they are not reviewed within the time limit, they will be invalid and must be re-admitted; It expires voluntarily at the statutory retirement age.

The third category is divided into five grades from low to high (primary electrician, intermediate electrician, senior electrician, electrician technician and electrician senior technician. The first four can be requested for the first time if certain conditions are met. To apply for a senior electrician, you must have an electrician grade certificate for three years). Please consult the local authorities for details.
