In the process of installing the socket, many methods, steps and precautions are involved, so what is the specific height standard of the socket? How to choose and buy household socket switch correctly? What I recommend to you today is these two aspects of information. It can be seen that the switch sockets in the market have different sizes and specifications for household appliances according to different installation places, and the corresponding heights are also different. We can comprehensively understand the following contents, and formulate appropriate installation scheme and scheme according to the actual situation.

A, installation socket height standard

1, the power switch is generally between 1.2m and 1.4m from the ground (the switch height is generally the same as the adult shoulder height), and it is installed at the same height with a difference of less than 5mm.

2. If several switches or multi-position switches are installed side by side, the position of the control appliance should correspond to the position of each switch function. For example, the leftmost switch should control the leftmost electrical appliance;

3. Ordinary power sockets without special requirements shall be installed at a distance of 0.3m from the ground, with the same height and a difference of no more than 5mm.

4. Wall sockets, desk lamps and wiring boards of audio-visual equipment. Generally, it is 0.3m above the ground (the living room socket depends on the TV cabinet and sofa);

5. The washing machine socket is off the ground 1.2m to 1.5? cm；

6. The refrigerator socket is 0.3m or 1.5m from the ground (depending on the location and size of the refrigerator);

7. The socket of air conditioner and exhaust fan is 1.9m to 2.0m from the ground.

8. The socket of the electric water heater should be installed on the right side of the water heater, which is 1.4m~ 1.5m away from the ground. Be careful not to put the socket on the electric heater.

9. The socket of the terrace should be above 1.4m from the ground, and be as far away from sunlight and rain as possible.

Second, how to correctly select the household socket switch

1, switch, socket and conductor section must be selected according to the working current of household appliances and the current of lighting lamps.

The lighting lamp is controlled by a switch, and the rated current of the switch must be greater than the total current of all the lamps it controls. It is safer to select the switch of 16A, and the power socket must have a branch circuit.

2, air conditioning power socket:

①? In an air conditioning circuit, there should be no more than two sockets;

②? More than 0.5 air conditioners should choose 16A socket;

③? 1.5 the following air conditioners can choose 10A socket;

④? The installation height of wall-mounted air conditioning power socket is generally not less than 2.2 meters;

⑤? Large-capacity cabinet air conditioner should be equipped with power circuit and power socket separately.

Because there are many household appliances in the kitchen and bathroom, it is advisable to set up a separate power socket circuit.

①? The number of power sockets in the kitchen should take into account the increase of household appliances in the future, and sockets should be reserved.

②? High-power electric water heater (1500W) should have a separate power socket loop.

③? The socket in the bathroom should be equipped with a splash box, and local equipotential connection must be made to improve the safety of electricity use.

④? Bedroom, living room and other rooms mainly illuminated by electricity can be equipped with two or three power socket circuits according to the number.

4. Sockets with protective doors must be used when the installation height is less than1.8m.. Mainly used to protect children's personal safety and avoid getting an electric shock due to naughty.

5. The socket circuit generally adopts 16A/30MA leakage protection circuit breaker. 10A- 16A miniature circuit breaker is generally used for lighting circuit. 16A-25A miniature circuit breaker is generally used for air conditioning circuit.

6. Choose 32-45A small circuit breaker or disconnector as the main switch of household distribution box.

The type of circuit breaker can be bipolar or 1P+N (phase+neutral). In case of short circuit or leakage fault, the circuit breaker can immediately cut off the phase line (live line) and zero line (zero line) of the power supply to ensure personal safety and the safety of electrical equipment.

7. Induction starting light sources such as fluorescent lamps and energy-saving lamps are not suitable for switch control with indicator lights.

The suggestion of installing sockets recommended to you today tells us that different sockets are installed in different places, and the corresponding height standards are different, and the screening cost of household socket switches in the early stage of purchase is also more complicated. So where should we start to learn? I believe that we can gain something from the above, and we can also know that it is the most reliable suggestion to formulate a suitable scheme according to our own usage habits and the structure and area of the wall itself, and in the process of selection, quality control is also crucial.
