How far is the distance between the socket from the ground and the socket in the living room of a formal suite?
The installation of sockets must comply with the requirements of national standards and specifications
1. The position of the socket must be correct
The surface-mounted socket should not be less than 1.8 meters from the ground (rural areas Old houses are equipped with such sockets); the distance between concealed sockets should not be less than 30 centimeters from the ground. The concealed socket panel should be close to the wall, with no gaps around it, and the installation should be firm. The surface should be smooth and clean, without cracks or scratches. Injury and decorative caps are complete; safety sockets (sockets with safety chips) should be used in children's activity areas, or their installation height should be no less than 1.8 meters. The sockets in the kitchen and bathroom should be at least 1.5 meters above the ground, and the sockets for air conditioners should be at least 2 meters away. Sockets installed in the same place should be of the same height.
2. Do not wire the socket casually
Install a single-phase two-hole socket. The right hole or upper hole facing the socket is connected to the phase wire, and the left hole or lower hole is connected to the neutral wire. ; Single-phase three-hole socket, the right hole facing the socket is connected to the phase line, and the left hole is connected to the neutral line; the upper middle should be connected to the protective earth wire (PE). PE wires must not be connected in series between sockets and should be connected to the ground wire alone. The neutral wire and protective ground wire of the three-hole socket must not be connected incorrectly.
3. The number of sockets must be sufficient
Regarding the number of sockets, the general requirement is: the distance between two socket points shall not exceed 3.66 meters. That is, if a household appliance cannot be connected to the socket from the left side, The sockets must be connected from the right side, and the number of sockets in the bedroom, living room and kitchen should be no less than 4, 7 and 4 respectively.
4. The grounding of the protective ground socket of the three-pin socket must be reliable
The grounding of the three-pin socket is the weakest loop connection for safe electricity use in rural households. Most households are not grounded at all. . Even the grounding is not standardized. For example, the grounding wire is just a piece of iron wire, and the grounding body is a nail fixed on the wall. Once the two are connected, it is considered to be grounded. Some users simply break off the three-prong plug from the chassis and use a two-prong socket instead of the three-prong socket. Users whose three-pin socket does not have a protective grounding when using household appliances with three-pin plugs. Once the metal casing of a household appliance becomes electrified, people who come into contact with the household appliance are in danger of being electrocuted. In order to ensure the safety of farmers using household appliances, farmers and rural electricity workers should pay enough attention to the protective grounding issue of three-pin sockets.
5. Install sealed sockets in humid places
Ordinary sockets should not be installed in humid places at home, such as kitchens and bathrooms, to prevent corrosion or leakage.
6. The sockets of high-power electrical appliances are directly connected from the household distribution box
Due to the working current of high-power electrical appliances (air conditioners, microwave ovens, induction cookers, washing machines, refrigerators, etc.) Large, the rated current of the socket used is not less than 10A. It is best to connect the connecting wires from the home distribution box. Use aluminum core wires with a cross-sectional area of not less than 2.5 square millimeters; choose copper core wires with a cross-sectional area of not less than 1.5 square millimeters. Multi-purpose sockets can be used for some frequently moved electrical appliances, but they need to be used with caution and do not turn on multiple electrical appliances at the same time. Ensure safe use.
7. The socket circuit must be protected against leakage
The electrical appliances connected to household sockets are basically mobile electrical appliances that can be touched at any time (vacuum cleaners, floor-standing or desktop fans and various small appliances) Home appliances) or fixed appliances (refrigerators, microwave ovens, electric heated showers and washing machines, etc.). When the wires of these electrical equipment are damaged (especially the wires of mobile appliances) or the live shell of the electrical equipment can be touched by human hands, there is a risk of electric shock. Except for wall-mounted air conditioner power sockets, other power sockets should be equipped with leakage protectors. A leakage protector is a protective appliance designed to prevent leakage or electric shock. When the leakage current of the electrical appliances and wires behind the leakage protector exceeds the rated value (the operating current of the household leakage protector is less than 30 mA and the action time is less than 0.1 seconds), the device trips and cuts off the power. It is often used in conjunction with protective grounding or protective zero connection to form a double insurance against electric shock.
8. Choose copper core wires for socket leads
Aluminum core wires are commonly used in rural households.
Although using aluminum core wire indoors saves a little money, the harm is huge. According to statistics from the U.S. Consumer Product Safety Commission (CPCS), the fire incidence rate of aluminum wire is 55 times that of copper wire. my country's national mandatory standard "Lighting Design Code", which was implemented on June 1, 1999, clearly requires that copper wires should be used indoors for lighting circuits. Therefore, the leads of indoor sockets must choose copper core wires.
9. There should be obvious differences between sockets with different voltages. Not interoperable
