Q:5 air conditioning can be used 4 square cable

You do not use the 9V power supply, a long time will burn the router.You'd better measure the original adapter voltage, if you want to extend the power cord, it is best to use a thick line of reliable connection, you can not start now, you can not start Depending on whether the extension line is too thin, causing the voltage drop too much.It is necessary to extend the front end of the adapter can extend the 220V power cord.

Q: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.

Q:25 square copper cable how much money one meter?

3000w electrical work at 220V voltage is about 13.6A (current = power divided by voltage). Copper core line of the working current is generally a square 4-6A. That is to say you use 3-4 square power cord more secure.

Q: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

Q: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.

Q: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!

heat shrinkable casing (MRSG) is a new environmentally friendly halogen-free flame retardant casing, inexpensive products, for wire, cable and wire terminals to provide insulation protection

Q: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

Q:3 by 16 cable is a few flat? How? That 5 by 16?

1 Definitions and basic tasks Communication lines and ancillary facilities Routine inspection operations are based on regional characteristics of regular light cable line inspection and protection line publicity, timely detection of problems, troubleshooting factors to ensure smooth communication; communication lines and ancillary equipment to make up Strong, to ensure that the optical cable lines and ancillary equipment integrity is good to prevent the occurrence of failure

Q:How do I ask for cable prices? How many tons is one or more?

As long as the line connected to the corresponding location, that is, audio cable audio and video cable, video cable can be used with the video line.

Q: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.
