In housing, the circuit is the most important and dangerous. It is the arteries of the entire residence. If it is not smooth, not only will the basic needs of life be problematic in the future. Therefore, before the check-in, you must check the electrical installation, not sloppy, check the electrical installation quality is the top priority of the inspection room. So where do you focus on the inspection of the electrical quality of finely-furnished rooms?

First, check the distribution box. Distribution box is available in every suite. Unscrew the distribution box to check whether the wiring is standardized: No connection is allowed for the incoming and outgoing wires, and there is a wrapper on the same wire to prove that there is a problem with the wiring. The power main circuit breaker shall be installed in the distribution box. The main circuit breaker shall have the function of overload short circuit protection and leakage protection. The switches in the distribution box must be firmly installed, each of them must be swung from side to side, and looseness should be promptly replaced.

Second, check whether the installation quality of the shunt switch in the distribution box is in place.

1. The shunt switch should have obvious shunt marks. If there is no mark, the property management professional can make up the class in time.

2. Check the lines one by one according to the shunt marks to see if the shunt marks match the actual ones.

3, lighting, sockets, air conditioning, bathroom, kitchen lines must be a separate circuit, not allowed to jump the gate.

Third, check the wiring system and switch sockets. The indoor wiring should be uniform in color separation and put through the pipe, and strong and weak electricity, different loops, and different voltage levels must not be put in the same pipe. Lighting switch must be phase (fire) line into the switch, switch off the ground not less than 130 cm. The left side of the socket with three eyes installed is the neutral line, the right side is the fire line, the upper port is the grounding line, and the outlet is not less than 20 cm from the ground. Also don't forget to check the toilet's equipotential box. The so-called equipotential box is the gray tin box of the bathroom. It will be connected to the bathroom's metal products such as water heads, metal towel racks, electric heating, cast iron bathtubs and other wires. Plays an anti-static, anti-electrical injury to human safety.

Fourth, check weak electricity. Check video intercom, emergency call button, home doorbell. If any questions are not clear, please promptly ask a professional to solve the problem. Telephone, cable, TV socket, and broadband outlet plug in to see if there is any loose or plugged in phenomenon, especially don't forget to open the weak box, pull the lines to see if each line interface is dummy. The distance between the power socket and the TV line, telephone, and network cable socket should not be less than 50 cm. Noise will occur when the distance is too close.
Since circuit problems are related to personal safety, the owner is best to ask a professional house inspection agency to fully test it and be completely safe.
