What are the hazards of an electrician working without a license?

Without a license, it often means that this "electrician" lacks the basic knowledge and operating ability of electricians, and it is likely that there will be illegal operation or misoperation in the operation process, which will lead to the damage of power equipment (electrical appliances), the expansion of circuit faults, and even disastrous consequences (such as fire, scrapping of lines and equipment, causing huge property losses and casualties).

It is very sad that it is impossible to identify a work-related injury and obtain legal compensation after the operator suffers personal injury or death due to unlicensed operation, and it will also be investigated for legal responsibility. For the losses caused by the unlicensed operation of power users, the person in charge of the unit has unshirkable legal responsibility, and will be severely investigated for responsibility (even criminal responsibility), and the insurance company will not compensate.

Therefore, any unit will not let people without electrician qualification operate the circuit without a license, and will not ask for trouble. Even qualified electricians are not allowed to take up their posts without a new certificate after their qualification certificate is revoked.
