2, don't pull the wire, to prevent electric shock or fire.
3, don't stand on the wet ground to move charged objects or try to clean charged household appliances with a wet rag to prevent electric shock.
4, fuse selection should be reasonable, avoid using copper wire, aluminum wire or iron wire instead, in case of fire.
5, the use of household appliances such as refrigerators, freezers, washing machines, etc. , should be equipped with grounding wire socket according to the requirements of product use.
6. When repairing or replacing the lamp holder, even if the switch is turned off, do not touch it directly by hand to prevent electric shock.
7. Every family must have some necessary electrical appliances, such as test pens, screwdrivers and glue tongs. There must also be fuses and fuses of various specifications suitable for household appliances.
8. Every household electric meter must be equipped with master insurance, and the master circuit breaker and leakage protection switch should be installed behind the electric meter.
9. In any case, it is forbidden to use copper or iron wire instead of fuse. The size of the fuse must match the capacitance. When replacing the fuse, remove the porcelain box cover and replace it. It is not allowed to tie the fuse directly in the porcelain box, and it is not allowed to replace the fuse with electricity (without opening the circuit breaker).
10. After the fuse is blown or the leakage is treated, the reason must be found out before turning on the power switch. In any case, it is not allowed to send electricity by short-circuit insurance or tripping mechanism of forced leakage switch.
1 1. When purchasing household appliances, you should carefully check whether the technical parameters (such as frequency and voltage) in the product manual meet the local power consumption requirements. It is necessary to know how much electricity is used and whether the existing power supply capacity of the family meets the requirements, especially whether the wiring capacity, plugs, sockets, fuses and meters meet the requirements.
12. When household power distribution equipment can't meet the capacity requirements of household appliances, it should be replaced and modified, and it is forbidden to make do with it. Otherwise, overload operation will damage electrical equipment and may also cause electrical fire.
13. When buying household appliances, you should also know their insulation performance: general insulation, reinforced insulation or double insulation. If grounding is used for leakage protection, grounding wire is essential. Even for electrical equipment with reinforced insulation or double insulation, it is beneficial to make protective grounding or zero connection.
14, household appliances with motors (such as electric fans, etc.). ), you should also know their heat resistance level and whether they can run continuously for a long time. Pay attention to the heat dissipation of household appliances.
15. Before installing household appliances, you should check the requirements of the product manual on the installation environment, and pay special attention not to install household appliances in an environment with damp heat, dust or flammable, explosive and corrosive gases as much as possible.
16. During indoor power distribution, the phase line and the zero line should be clearly marked, and they should be consistent with the wiring of household appliances, and they should not be staggered.
