Hello! What does a property maintenance electrician do! I graduated from electronics! Can you do it? There is also a four-level electrician certificate!

Property maintenance electrician is relatively simple and has low requirements. Maintenance of main lighting circuit, simple control circuit and power distribution room also need to be operated and maintained on duty. There should be no problem if you graduate from electronics, but you need to take an electrician's certificate (SERC's electrician's network access certificate, and Safety Supervision Bureau's electrician's special operation certificate). What department issued the certificate of level 4 electrician?
