How much current can a 10 square line carry?

How much current can a 10 square line carry?

Copper wire 80A
Aluminum wire 50A
This is the general situation
Heat dissipation is not good to reduce, such as through the tube
Instantaneous can be high
Skin effect should be considered in high frequency

How much current can a square wire withstand?

Copper wire 9A cable ampacity: cable ampacity refers to the amount of current that a cable line passes when transmitting electric energy. Under the condition of thermal stability, when the cable conductor reaches the long-term allowable working temperature, the cable ampacity is called the long-term allowable ampacity of the cable

How far can 220 V alternating current conduct in water?

Pure water is non-conductive, and the resistivity of natural water is not equal due to different impurity composition. For the voltage of 220 V, the water with high resistivity is tens of centimeters, and there is no feeling. The water with low resistivity is several meters away

What is the line current of 2kw-220v AC generator?
I don't understand that

On the first floor, P = root 3 times u * I
I=5.249
