What's the difference between a maintenance electrician and a residential electrician?

These two kinds of jobs used to be the same, but they have been separated in recent years. According to the type of work, the maintenance electrician focuses on the scope of maintenance, electricity consumption and control loop, mainly to restore the existing and faulty electrical circuits and equipment to their original state and make them run normally. Electricians mainly include high-voltage equipment such as design, substation, transmission and distribution. However, there is no absolute clear boundary between the two, and with the improvement of level and technology, the overlapping scope of the two is also greater. That is to say, if the electrician has a high level, he must know how to maintain the electrician. If the level of maintenance electrician is high, it is necessary to understand electrician knowledge. The scope of application of the certificate is related to the provisions of the employer. With electrician certificate, you can generally engage in maintenance electrician work, because the nature of the two types of work is basically the same, and some units still can't tell whether there are two types of work. But pay attention to study more, after all, technology is the main thing. I wish you success in your job search.
