FAQ

Is the cable head made of every building?
Generally have every building floor wiring closet must be connected to the big cable. The big cable comes in to do the cable head
6 square cable up to how many air conditioning (1.5P)
7 kilowatts of electricity with what specifications of the wire if it is single-phase 220V, then 7 kilowatts of current is 7000 × 220V = 31.8A, check the electrical manual 4 square copper wire interception is 33A, to meet the requirements.
5 air conditioning can be used 4 square cable
Such as the extension line added to the adapter primary (city side) certainly easy to use. Extended by two meters, the router does not start, may be extended wire diameter is too thin, bold wire try. If not, choose 6V2A adapter try, the voltage is too high will burn the router. Increase the current is no problem, just like the computer's power, 300-watt power can be replaced, and small is not OK.
Can the main cable be aluminum cable? And explain why, thank you!
Excretion training is the use of positive reinforcement, that is, a variety of food, toys, the best time to reward
The difference between nylon balls and geese and ducks
It depends on the thickness of the wires you use. The thicker the copper wire is, the better. Because the distance will be a voltage drop. So be it, you use a multimeter to look at how long you charge when the output voltage is how much. If you can more than 50 should be no problem. If the voltage is relatively low can change a rough wire, or find a few wires in parallel can also be. I do not know if you can understand it. Even if there is a voltage drop if it is not very powerful should not be the problem, the worst result is the battery charge dissatisfaction. You can try to see how the effect of the day. Certainly will not break your equipment and battery, rest assured it
1000 kW 600 m cable to use much
Depends on the load is emotional, resistive, should be too long cable, consider the pressure drop. Generally consider 2.5 or more.
How much of the cable with the switch?
The switch is not selected according to the cable and is selected according to the current. The cable is determined by the size of the power (converted to current) and the distance from which the distance is far. The greater the power distance, the greater the cross-sectional area of the required cable. For example: 15KW motor selection cable current I = P / 1.732UcosΦ = 15 / 1.732 / 0.38 / 0.8 = 28A if it is close (within tens of meters), copper cable 6 square millimeters, aluminum cable 10 square millimeters. If it is in the distance (a few hundred meters), copper cable 10 square millimeters, aluminum cable 16 square millimeters. If it is long distance (close to kilometers), copper cable 16 square millimeters, aluminum cable 25 square millimeters. The switch is regardless of distance, completely based on the load current to choose, generally according to the load current of 1.5 times to 2 times to choose.
