(10), when wiring indoors, the phase line and the zero line should be clearly marked and consistent with the wiring of household appliances, and they should not be staggered.
(1 1), the connection between household appliances and power supply must use switches or plugs, and it is forbidden to directly insert wires into socket holes.
(12), all household appliances requiring protective grounding or safe zero connection should adopt three-pin plugs and three-pin sockets, and two-pin plugs and two-pin sockets are not allowed to be used instead, resulting in neutral grounding (or zero connection) wires.
(13), it is better to have no connector in the middle of home wiring. If there must be a joint, it should be firmly contacted, wrapped with insulating tape, or a porcelain junction box. Standard uses medical tape instead of electrical tape to wrap joints.
(14), wires and switches, circuit breakers, fuse boxes, lamp holders, etc. The connection is firm and reliable, and the contact is good. The multi-rubber flexible copper wire connector should be twisted first, and then placed under the connector screw gasket to prevent the thin strands from spreading and contacting another connector and causing short circuit.
(15), household wiring shall not be directly laid on flammable building materials, and porcelain beads or clamps must be used if wiring is needed on wood; Porcelain sleeves must be used to penetrate the board. Flammable plastics and other flammable materials shall not be used as decorative materials.
(16), the grounding or neutral line is normally not charged, but in case of leakage after disconnection, the shell of the right electrical appliance will be charged; In the case of short circuit, the grounding wire also passes a large current. For the sake of safety, the specification of the grounding (neutral) wire shall not be lower than that of the phase wire, and switches, fuses or connectors shall not be installed on it.
(17), the grounding wire should not be connected to the tap water pipe (because the tap water pipe joint is now sealed with insulating tape and has no grounding function); Do not connect it to the gas pipe (in case of gas explosion caused by electric spark); Don't connect it to the ground wire of the telephone line (in case of strong current and weak current); Nor shall it be connected to the down lead of lightning rod (to prevent lightning strike).
(18), all switches, knives and fuse boxes must be covered. Bakelite cover plate is aging and incomplete and must be replaced. Dirty and wet people must be wiped clean before use after power failure.
(19), the power cord should not be dragged on the ground to prevent the power cord from tripping and damaging the insulation.
(20) Before household appliances are tried out, all switches and buttons should be placed in the original stop position according to the requirements of the manual, and then the start-stop operation sequence required by the manual should be carried out. If there are moving parts, such as a head-shaking fan, sufficient motion space should be considered in advance.
(2 1), when household appliances are found to be sparking, smoking or burning after being electrified, stop immediately and cut off the power supply for inspection.
(22) When moving household appliances, be sure to cut off the power supply to prevent electric shock.
(23), around the heating appliance must be far away from flammable materials. Electric stove, heating stove, electric iron and other heating appliances should not be placed directly on the board to avoid fire.
(24), it is forbidden to touch the live switch with wet hands; It is forbidden to plug the power supply with wet hands; When unplugging the power plug, fingers must not touch the metal part of the contact; Never replace electrical components or light bulbs with wet hands.
(25) Used in household appliances (such as hair dryer, electric soldering iron, etc.). ) It is often used in your hands, and it is forbidden to wrap wires around your hands.
(26) Household appliances in contact with human body, such as electric blankets, electric oil caps, electric shoes, etc. Before use, it should be electrified for testing and inspection, and it can only touch the human body after there is no leakage.
(27) It is forbidden to move household appliances by dragging wires; It is forbidden to pull the plug by dragging the wire.
(28), when using household appliances, plug in the neutral end of the socket first, and finally close the knife switch or plug in the live end socket; On the contrary, when stopping the use of household appliances, first pull the circuit breaker on the live side or pull out the socket on the live side, and then pull out the socket on the dead side (if necessary).
(29) When it is necessary to cut off the power supply wire in an emergency, insulated electrician tongs or insulated handle cutters must be used.
(30), rescue electric shock personnel, first of all, to disconnect the power supply or use wood, insulating rod pick open the power cord, don't directly drag electric shock personnel by hand, so as to avoid serial electric shock.
(3 1), household appliances, except refrigerators, should be turned off at will, especially electrical appliances, to prevent fires caused by long-term heating.
(32), bed switch is strictly prohibited. Except for electric blankets, don't lead charged electrical equipment to the bed, close to the sleeping human body. Even if an electric blanket is used, it is recommended to turn off the power supply after heating to ensure safety if it is not necessary to keep warm all night.
(33), household appliances burning, smoking, fire, must immediately disconnect the power supply, shall not be sprayed with water or foam extinguisher.
(34), indoor wiring and electrical equipment insulation should be checked regularly, found that the damage should be promptly wrapped with electrical tape.
(35) The insulation resistance of household appliances that have not been used or reused for a long time before the rainy season should not be lower than1mΩ when measured with a 500V shaking table, which can be considered as good insulation and can be used normally. If there is no shaking table, at least use a test pen to regularly check whether there is any leakage.
(36) For household appliances that are often used, keep them dry and clean. Do not wipe the surface of household appliances with corrosive or conductive liquids such as gasoline, alcohol, soapy water and decontamination powder.
(37) After household appliances are damaged, please ask professionals or send them to a repair shop for repair; Non-professionals are strictly forbidden to open the shell of household appliances under live conditions.
