What is the danger of electricians without a license?

No license, often means that the "electrician" lacks the basic knowledge of electricity and basic operating ability, in the process of operation is likely to be illegal or incorrect operation, resulting in damage to electrical equipment (electrical appliances), the expansion of circuit failures, and even lead to catastrophic consequences (for example, fires, lines, and equipment scrap caused by huge). (e.g., fires, huge property losses due to the destruction of lines and equipment, and injuries and deaths).

The unlicensed operation of the operator's own casualties, can not be recognized as a work-related injury, can not be legally compensated, but also be held legally responsible, very sad. For the power unit, unlicensed operation of the loss caused by the head of the unit can not be shirked legal responsibility, will be severely pursued (or even criminal liability), the insurance company will not be compensated.

So, no organization will allow unqualified electricians to operate circuits without a license, and will not ask for trouble. Even if a qualified electrician has not been re-certified after having their license revoked, they will not be allowed to work.
