Electrical Frequently Asked Questions and Knowledge (4)

Home Safety Electricity General Knowledge:

(1) Every family must have some necessary electrical appliances such as electroscopes, screwdrivers, and glue clamps, as well as fuses and fuses of various specifications suitable for the use of household appliances.

(2) Each household meter must be equipped with general insurance before it. The meter should be equipped with a total knife gate and leakage protection switch.

(3) In any case, it is forbidden to use copper or iron wires instead of fuses. The size of the fuse must match the capacity used. When replacing the fuse, remove the porcelain cover and replace it. Do not lap the fuse directly in the porcelain case. Do not replace the fuse in the live condition (without opening the knife).


(4) After the fuse or leakage switch is blown, the cause must be ascertained before switching on the switching power supply. Under no circumstances shall the conductors be short-circuited or pressed against the leakage switch tripping mechanism for forced transmission.

(5) When purchasing home appliances, you should carefully check whether the technical parameters (such as frequency, voltage, etc.) of the product specification are in line with the local electricity requirements. It is necessary to know how much power is consumed and whether the existing power supply capability of the family satisfies the requirements, especially whether the wiring capacity, plugs, sockets, fuses, and meters meet the requirements.


(6) When the household power distribution equipment cannot meet the capacity requirements of the household appliances, it should be replaced and modified. It is forbidden to make use of it. Otherwise, overloaded operation can damage electrical equipment and may cause electrical fire.

(7) It is also necessary to understand the insulation properties of household appliances: whether they are general insulation, reinforced insulation or double insulation. If it is grounded for leakage protection, the grounding line is essential. Even for reinforced or double-insulated electrical equipment, it is beneficial to provide protective grounding or zero protection.

(8) Household appliances with electric motors (such as electric fans, etc.) should also be aware of the heat-resistant level and whether they should be operated continuously for a long time. Pay attention to the heat dissipation conditions of household appliances.


(9) Before installing household appliances, check the requirements of the product specification for the installation environment. Pay particular attention to the possibility of not installing the household appliances in a hot, dusty or flammable, explosive, corrosive gas environment under possible conditions. .

(10) When laying indoor wiring, the phase line and neutral line should be clearly marked and consistent with the wiring of household appliances.

(11) When the household appliance is connected to a power source, a switch or plug connector that can be switched off must be used. It is forbidden to insert the wire directly into the socket hole.
