Residential property electrician! What should the most basic students learn?

Hehe, it seems that you and I almost started working with certificates. It doesn't matter, as long as you have a good service attitude and technology, the property requirements that can be improved at work are not very high, even if you have no foundation at all. The premise is that you have confidence in yourself if you are willing to work, and you can gradually understand the replacement principle of fluorescent lamps and various water valves. And how to operate the switch control in the switch box. To put it bluntly, I am familiar with the environment and will do general maintenance. Technology should be learned by yourself in the future work. Wish you success!
