How to decorate the circuit so that the room is warm and safe

A: stitches and change lines

If you are renovating an old house, the original ones are all aluminum wires, and you must remove them because the aluminum wires can no longer meet the needs of modern household electricity . The construction personnel must not only change the wires of the switch and the plug in order to cope with the occupants. Otherwise, the occupants will use electricity to bury hidden safety hazards.

After removing the old line, replace it with plastic copper wire . According to the new standard, the cross section of each residential house entrance line should not be less than 10 square millimetres. This way, for ordinary families, the lamps and lanterns use a 1.5 square millimeter line, and the switch socket is 2.5 square millimeters. The circuit for installing high-power electrical appliances, such as air conditioners, should be routed along a 4-square-mm line. For the entire line, the number of branch circuits should not be too small, generally should be all the way to go lights, air-conditioning go two-way, sockets go three to four. The advantage of doing so is that once a circuit has a short circuit or other problem, the scope of power outage is small; it will not affect the normal operation of other routes.
