Why can't there be joints in the threading pipe? Where should the connector be?
It is forbidden to connect the wires in the threading pipe, that is, if the length of the wire is not enough, the joint of the wire cannot be in the threading pipe, and it should be connected in the junction boxes such as switches, sockets, lamp cap boxes, etc. Otherwise, the inside of the pipe may be easily blocked and the heat radiation may be poor. Points are not easy to find, maintenance is difficult, and it may cause electrical fires.
Why is it forbidden to use mobile bedside lamps?
The movable bedside light switch is connected to the switch by a soft insulated wire. If the wire and the switch are separated during use, the exposed wire end may cause fire or electric shock.
Why do lighting switches must be connected in series?
If the light switch is connected to the zero line in series, although the light does not turn on when the light is turned off, the phase line of the light head is still turned on, and people think that the light does not light will erroneously think that the light is in a power-off state. In fact, the ground voltage at each point on the luminaire is still a dangerous voltage of 220 volts. If people touch these actually live parts when the lamp is off, it will cause electric shock.
Therefore, the switches of various lighting switches or single-phase small-capacity electrical equipment can only be connected in series to ensure safety.
After finishing the renovation, what are the problems that electric acceptance should pay attention to?
All switches of the circuit must normally control the power of each channel. All sockets must be powered on. The left-right phase should be zero. The distance between strong and weak power should be no less than 30 cm.
What is the wiring box? The wiring box is a branch of the integrated cabling product. It is a kind of cabling product with Chinese characteristics. It is mainly based on the actual needs of the Chinese market, compared to the general cabling network, the advantage of the wiring box It is a relatively low-cost, high-end office building due to a relatively large project, the network structure is more complex, the reason is relatively high engineering costs, the project is still more inclined to use integrated wiring network instead of wiring box, and wiring box is suitable for a small number of wiring, wiring What is a "family comprehensive weak wiring system"?
î—¥ î—¥ In a nutshell, the integrated weak home wiring system is to comprehensively consider all the needs of the home and the various cables and equipment to be used.
We must pay attention to those matters when embedding weak currents? 1, when the wiring should be PVC flame-retardant tube, but also horizontally vertical, in case of turning to use elbow. 2. Weak electricity generally does not go to the ground. 3. The minimum distance between high-power and low-voltage channels is 300mm. 4. The audio cable and the broadband cable cannot be connected. The telephone line network cable must use a special connector or distributor. 5. After the weak current is well-arranged, it is necessary to conduct a test to ensure that the weak electricity flows smoothly after sealing the slot.
