In home circuit construction, special attention needs to be paid to the following points:
1. The construction personnel should have a post operation certificate issued by the local labor department within the validity period.
2. The materials used should be national standard products or have safety certification marks to ensure a safe service life.
three. Construction should strictly implement the specifications and process standards
1 When carrying out various line shift transformations, first determine the position of the line terminal socket, and draw the exact position and size on the wall. Then, proceed to the nearest similar socket lead. The method of the lead is: If the socket is in the wall, The upper part is slotted vertically upwards in the wall and is installed in the installation line of the decorative corner line at the top of the wall; if it is in the lower part of the wall, it is vertically slotted downwards to the bottom of the skirting board. The groove depth is about 15 mm, the wire conductor is loaded into the sheath, and it is placed in the wall groove and smoothed with cement mortar to fix it in the wall. If the original socket is reserved, reinstall it in its original position. If it is not retained, block it with cement mortar after filling it with bricks. The wire along the ground, when installing the skirting board, lies on the inner side of the bottom of the skirting board. The wire along the top corner is concealed inside the decorative corner line when the decoration line is installed.
2 The construction specifications of the circuit renovation project should be consistent in the depth of trenching, and the trench line should be straight. After the control line is ejected on the wall surface, the wall surface is cut with a marble machine and manually grooved. When installing the circuit, the bushing must be added. The connection of the bushing should be tight and smooth. The corner inside the corner should be cut and the arc-shaped interface on one side of the incision should be cut and installed. After the wire is installed into the casing, the wire fixing clamp should be used. After the wire is fixed in the wall and the wall surface, it is concealed by plastering or concealed by the skirting board and the decorative corner line. The installation of the outlet box shall be preceded by a hole in the wall. After the wire is inserted into the box, the box is placed into the hole and the wire is fixed to the panel and the panel is fixed on the box. The method of installing the power switch is the same as that of the outlet box.
3. Use copper wire for the wire and configure it according to the capacity. Not too thin. It is recommended that the wire diameter of the air conditioner should be 4 square millimeters of wire; the socket should use 2.5 square millimeters of wire; and the general lighting fixture should use 1.5 square millimeters of wire. When wires are routed through the hollow floor, they must be piped; wires of different voltages such as lighting lines, telephones and television lines must not be put in the same pipe; the power outlet panel should be the left zero line, the right phase line, and the upper ground line. Wrong; zero line, phase line, ground wire with different colors.
4. The wiring is applied to the construction of the dark pipe wiring. When the electrical wiring is performed, the PVC pipe must be used for the laying of the dark pipe. The PVC cable trunking must be used for laying the open wire. Avoid cracks on the wall caused by the pick-off during construction to destroy the wall structure. When laying, the number of conductors used in the pipe should be changed according to the number of conductors. Within the same pipe, it should not exceed four. It is forbidden that the conductors will occupy the space in the pipe. Air conditioners, lighting, and outlets should be shunted and controlled, usually at least four ways. Lighting goes all the way, air conditioning goes all the way, socket goes three to four ways. The advantage of this is that once a circuit has a short circuit or other problem, the scope of power outage is small and it will not affect the normal operation of other circuits. The distance from the power line to the telephone line and TV line should be greater than 50 cm. The pipeline should be fixed with the structure. The junction box should be installed at all switches, sockets, and lamp positions.
In addition, if the pipeline is too long or there are too many corners, a junction box should be set at a certain distance. No wire connector is allowed in the pipe. The bent position of the wire protection tube should use the matching elbow tool or matching elbow, and there should be no folds. The distribution control switch should be reasonably configured according to the specifications. If the configuration is too small, it will cause inconvenience in use. If it is too large, it cannot guarantee the safe use of electricity. Another important point is that during construction, the pipeline should be installed first, and then the conductors should be used. This avoids the possibility that the wire cannot be twitched when the line is changed in the future.
Also to remind you is that when your home improvement project is completed, don't forget to ask the construction unit for a set of electrical circuit completion drawings for your future maintenance.
