if you decorate an old house and used aluminum wire, it's — It must be removed, because the aluminum wire can no longer meet the needs of modern household electricity. The construction personnel must not only change the wires at the switches and plugs in order to cope with the residents, otherwise it will bury potential safety hazards for the residents to use electricity in the future

after removing the old wire, replace it with plastic copper wire. According to the new standard, the cross-section of the incoming line of each house should not be less than 10 square millimeters. In this way, for ordinary families, 1.5 square millimeters for lamps and 2.5 square millimeters for switches and sockets can be used, while for the installation of high-power electrical appliances such as air conditioners, 4 square millimeters of lines should be used separately. For the whole line, the number of branch circuits should not be too small. Generally, it should be the first way for lights, the second way for air conditioners, and the third to fourth way for sockets. The advantage of this is that once a short circuit or other problems occur in a certain line, the scope of power failure is small; It will not affect the normal work of other circuits
