FAQ

Is the cable head made of every building?
Building in accordance with the floor or unit configuration distribution box, there are office buildings using a total box. Where there is a cable out of the situation, must be wrapped to make the cable head, according to the choice of distribution box circuit breaker wiring crimp or not crimp the cable terminal. In other words, the cable head must be made, but not necessarily crimp the cable terminal.
5 air conditioning can be used 4 square cable
Lengthened low voltage side, the line resistance increases, the voltage drop increases. Reduced load capacity. So that the router due to insufficient supply voltage and can not work properly. It is not allowed to use 9V power supply. Voltage is too high, the router part of the internal power supply increased power, heat increased, it is possible to burn the router. It is necessary to extend the power cord, I suggest you extend the power supply side (220V one end) safe and reliable. Increase the voltage to increase the supply current, in the electrical working voltage range (with the electrical work voltage range) is allowed, too low electrical appliances can not work properly. Too high there is the risk of burning appliances, according to your actual situation, marked 5V0.2A that the router works at rated voltage, so the way to improve the supply voltage is not applicable. So you can only improve the power supply power (that is, you say to increase the power supply current rather than voltage). With the reserve power, it will provide enough current at the rated voltage (the router as a resistor, from I = U / R, you can know the danger of increasing the voltage) need help please message
Can the main cable be aluminum cable? And explain why, thank you!
Reply to the landlord: I read a part of the literature, more Google is aware of the following part may be your reference weak construction specifications 1

If the 2.5 square copper wire for the output extension cable, 20 meters distance, the total resistance of about 2 * 1.7 * 0.2 / 2.5 = 0.272 (ohms), the current maximum 1.8A, the voltage drop is 0.272 * 1.8 = ), The charging voltage is 55-0.5 = 54.5 (volts), a difference of about 1% will not have any impact on the battery. However, the third floor, said Ye Hao, you can put the charger put the debris room, from your house put a 220V power cord down, home and then engage in a switch control. It is best to design a light at home, can intuitively see if the electricity is full. That's better. Design light, teach you a way: to find a bad leakless protector, open there is a coil-like ring-shaped stuff, called zero sequence current transformer, it will be down, be careful, do not put Transformers inside the coil hurt, get down, in the transformer two thin lines connected to a light-emitting diode. And then your 220V power cord line of fire from the center of the sensor through, around 3-5 turns. In this way, as long as there is current flow, the light-emitting diode will be bright, when the charge is over, the charging current is close to zero, the light-emitting diode will be extinguished. You can from the light-emitting diode is lit to determine whether the electric has been filled. I also have an electric bike that is so charged.
How do I ask for cable prices? How many tons is one or more?
Cable bridge grounding should belong to the protective grounding, grounding resistance at a cross point is not greater than 50 milliohms, no jumper no more than 5 milliohms
Does anyone know the "line buckle" classification (including shape / size / material / has been some commonly used size!) Line deduction is a hardware products! For daily necessities!
In accordance with the relevant safety regulations, the power cable should not be parallel to the top of the thermal pipe laying, when can not be avoided, the interval distance should not be less than 1000mm, during which should also take effective insulation measures. Power cable and thermal pipe cross, the thermal pipe insulation layer, the separation distance should be not less than 500mm, no insulation layer should not be less than 1000mm, and in the cross with the insulation board to be protected, the length of the insulation board should not be less than d + 2000mm (d for the thermal pipe insulation layer diameter).
How much of the cable with the switch?
The switch is selected according to the current. General switch = (2-2.5) Current three-phase current = P / 1.732 / 0.38 / 0.8 Single-phase current = P / 0.22 / 0.8
