Dual TV socket: Two TV signal lines can be connected.
TV plus phone: one interface to the TV, one interface to the phone (RJ11).
Socket wiring rules: grounding on the left zero right fire:

If the fire wire, neutral wire or ground wire is connected incorrectly, it will likely cause a leakage accident. Therefore, the wiring of the wiring hole on the socket must follow the rule of “Left Zero Right Fire Grounding”. “Left zero right fire grounding” means facing the front of the three-hole socket (not facing the back side with the wiring hole), the left one jack is connected to the zero line, the right side socket is connected to the live line, and the upper side is the grounding line of the jack. If it is a two-hole socket, the left side is normally connected to the neutral line, and the right side is connected to the live line. Of course, a better socket generally has a marking indication next to the wiring hole, which is convenient in discriminating. Zero line: N, fire line: L, ground line: E, PE.
The application meaning of the socket protection door:

The National Electrical Code stipulates that sockets with a height of less than 1.8 m should be installed when using a safety socket with a protective door. At the same time, there are provisions, in addition to air-conditioning outlets and some special-purpose sockets, the normal indoor socket is 300mm away from the ground. In other words, the sockets used in homes should generally have protective door settings.
The protective door mainly prevents electric leakage accidents caused by accidental insertion of external metal, especially for children. Children tend to have a strong curiosity about novelty. For sockets that are within easy reach of the room, they may use fingers or other hard objects to insert the socket. Protecting the door can greatly reduce the risk.
The protection door is located in the socket socket and can be visually inspected. High-quality socket protection doors are generally made of black nylon 66 material, while quality secondary protection doors may use materials such as ABS. If inferior materials are used, scratches may appear on the protective door due to repeated scraping of the pins, which increases the difficulty of plug insertion.
However, many outlets on the market, even if there is a protective door, can be inserted with a screwdriver or a key (it is recommended not to test at home, there is a danger of charging). This is due to the unreasonable design of the protective door. The technically better protection door adopts the anti-monopolar insertion design. Two-pole plug, only two pins can be inserted at the same time to open the protection door. The anti-monopole insertion of the three-pole plug generally has two designs. One type of grounding pole has no protection door, and the fire and zero poles have to be inserted at the same time to open the protection door; the other three poles have protection doors at the grounding pin top. When the protection door is opened, the fire and zero pole protection door will open (a qualified three-pole plug, the grounding pin should be slightly longer than the other two poles).
The installation position of the switch:

The switch installation position is also very particular, and improper installation is likely to cause trouble in future use.
1, the switch installation height is generally 1.4 meters from the ground, and at the same height, the difference can not exceed 5mm;
2, the switch next to the door is generally installed on the right side of the door, but not behind the door;
3, several switches installed side by side or multi-position switch, the position of the control appliance should correspond to the position of each switch function, such as the leftmost switch when controlling the opposite leftmost appliance;
4. The necessary switch can be installed on the wall desk and the height of 0.5 m above the bedside table, so that the user can control the indoor electrical appliances without getting up.
5, kitchen, bathroom, terrace, switch installation should be as close as possible to the water area. If close, when adding a switch splash box;
6. Above the kitchen stove, you cannot install the switch.
Installation location of the socket:

1. The lower edge of the general socket is 0.3 meters away from the ground and installed at the same height, and the difference cannot exceed 5 mm;
2, each wall of the living room bedroom, the distance between the two sockets is not higher than 2.5 meters, within the range of 0.6 meters, at least one spare socket is installed;
3, the washing machine socket is between 1.2 meters and 1.5 meters from the ground, it is best to choose a switch socket;
4, the refrigerator socket is 0.3 meters or 1.5 meters from the ground (depending on the location of the refrigerator); #p#page title#e#
5, split type, wall-mounted air-conditioning socket should be set according to the reserved hole position of the outlet pipe 1.8 meters from the ground, window air-conditioning socket can be set at the side of the window 1.4 meters away from the ground, the cabinet air conditioner power socket should be at the corresponding position Set at 0.3 meters above the ground;
6, the hood socket according to the design of the kitchen cabinet, installed at a height of 1.8 meters to 2 meters from the ground, it is best to cover the discharge pipe;
7, the electric water heater socket should be installed on the right side of the water heater from 1.4 meters to 1.5 meters from the ground, be careful not to set the socket above the electric heater;
8, the terrace socket is more than 1.4 meters away from the ground, and as far as possible to avoid the scope of sunlight, rain and water;
9, kitchen, bathroom, terrace, socket installation when as far as possible from the water area. If it is close, add a socket splash box. A hair dryer and a power socket for shaving can be set beside the basin mirror, 1.5 to 1.6 meters from the ground;
Warm Tips: Generally speaking, we will install two five-hole sockets on both sides of the bedroom bed, but have you found that it is not enough for many times - bedside lamps, notebooks, mobile phone chargers, electric blankets... These objects, in addition to laptops, are mostly inserted with two eyes.
