To select the proper cable size you need to know all of the following:
circuit ampacity needed
ambient temperature
length of circuit from point 1 to point 300
number of conductors in the raceway or cable
type of insulation being used
voltage: whether above or below 380 volts
and for some pieces of equipment, the manufacturer's instructions.
If you know the kilowatt rating of the load you need to either know the supply voltage or the impedance of the load in order to find out the amperage required, which is what dictates the size of conductor needed. It is more likely you would know what the supply voltage is (likely 120 or 240 Volts).
To find amperage use the formula:
I = P/E
where I is Amperage, P is power in watts, and E is voltage
Example:
1200 Watt load on a 120 Volt line
I = 1200/120
=10 Amps
When you know the required amperage you need to look at the type of wire needed. IE inside your home, in a wet location, in an attic etc. (in the Canadian Electrical Code this is table 19)
Once you have selected a wire type then you can select a wire (in the Canadian Electrical Code this is table 2)
If you are asking how do you determine an appropriate cable to supply a given load in kilowatts, then you need to know the supply voltage in order to determine the current drawn by the load. You then need to check the appropriate cable tables (in your electrical code book) -but you will also need to know the number of cores, the type of conductor, the type of insulation, how it is to be installed, etc., as well as the load current.
To answer this question the size of the cable or the amperage of the load is needed to calculate the correct wire size and connectors to fit the cable.
100 kw is the power drawn by the load. to calculate the cable size you need to know the voltage. From that you can calculate the current. this decides the cable size. for example if the voltage is 400Volts then the current flowing in the circuit when the load is 100 KW will be 250 amps. (100,000/400). for 250 amps to flow with out causing excessive heating of the cable the cross sectional area of the copper cable should be 150 sq mm.for a round cross section the diameter will be roughly 15mm.
To answer this question the voltage of the unit must be given.
The cable size is : 4*25 mm2
6mm cable
The kilowatts will very depending on the size of the heating element(s) and the size of the pump(s).
Without knowing what the size of the distribution panel amperage rating is, an answer can not be given as to if 6.5 more kilowatts can be connected.
With out knowing the amperage rating of the panel, an answer can not be given.
The only way to determine the cable wire size needed for a 1000 watt air conditioner is to find the load size. To get the load size you will need to use the formula Amps = Watts or Volts. With that being said, you will need a number 14 copper wire.
To answer this question the size of the cable or the amperage of the load is needed to calculate the correct wire size and connectors to fit the cable.
If you know the size of the load to be served, multiply it by 125% ( times 1.25) and choose a conductor that is rated for that ampacity or higher.

Your question makes no sense.
To answer this question the voltage of the unit must be given.
Just try different sizes until you find the correct size.
