What happened to the sudden power failure in my new house? Please ask the electrician to explain.
Judge in several steps:
1. First, judge whether the room is partially blacked out or the whole house is blacked out.
2. If there is no electricity in the whole house, judge whether there is a power outage (see if there is electricity in the house next door).
3. If there is no power failure, check whether the switch in the electric box trips (if the old knife switch is used, check whether the fuse is blown) or whether there is poor contact at the end of the line.
4. If there is nothing abnormal in the electrical box, it needs to be detected by tools and operated by professional electricians.
