Electricians are so difficult to learn.

Electrician can be divided into maintenance electrician and operation electrician. I only introduce maintenance electricians: the teaching materials of the Labor Bureau are mainly based on theory, which has little influence on your future work. In terms of technology, I suggest that you first need to learn the typical knowledge of electric drive, such as three-phase asynchronous motor star delta step-down starting, autotransformer starting, typical combined circuits of contactors, relays and motors and related knowledge. Secondly, you need to know about PLC. Related knowledge and common maintenance methods of single chip microcomputer. Because the current development direction of factory equipment is intelligent and unmanned, PLC and single chip microcomputer are what modern electricians must learn. In terms of safety, you must remember not to touch the equipment you don't understand, and always keep safety awareness! Otherwise, I will regret it as much as I do ... but I don't regret that I am an excellent electrician! good luck
