Wire sizing is based on the amperage. The formula you need to find amperage from HP for single phase is
, I = HP x 746/E x %eff x pf. For three phase I = HP x 746/1.73 x E x %eff x pf.
A standard motor's efficiency between 5 to 100 HP is .84 to .91.
A standard motor's power factor between 10 to 100 HP is .86 to .92.
I = Amperage, E = Voltage.
When you have calculated the amperage ask a electrician to look up the wire size for that specific amperage. He should have a code book and there is a list of wire sizes and amperages. The quickest way of finding the amperage is by looking on the motor's nameplate. There you will find all of the information that you need.
Cables spaced apart on cable ladder, shaded from sun
you need the current of motor or the KW/HP rating
Cable sizing is based on amperage of the load. The rating of the capacitor bank and the voltage at which it operated need to be stated to give an answer.
A 0.15Cu cable has a rating of 382 amps summer and 476 amps winter. 0.2Cu allows 425/530 amps. That is for outdoor use in overhead lines.
Wire sizing is based on the motors full load amperage. The amperage can be calculated but a voltage has to be stated. I = W/E. Amps = Watts/Volts. Restate the question with a voltage and an answer can be given.
With out knowing the amperage rating of the panel, an answer can not be given.

for DC load and if its copper wire the cross section of the conductor wire is generally calculated as 1/4 th of the current rating . Eg for a DC load of 16 amp the copper conductor with 4 mm square is selected.
A 0.15Cu cable has a rating of 382 amps summer and 476 amps winter. 0.2Cu allows 425/530 amps. That is for outdoor use in overhead lines.

The ambient insulation rating of wires and cables is imprinted on the wire and cables. The labels on the cables will tell you the wire size, number of conductors and temperature rating of the wires and cables. The higher the cable and wire temperature ratings the higher the amount of current that is allowed to be drawn by the wire and cable according to the electrical code book.
To calculate the cable size for a 30-meter run, you need to consider the current rating of the circuit, voltage drop limits, and the type of cable insulation. Use a cable sizing calculator or consult a professional electrician to determine the appropriate cable size to ensure safety and efficiency of the electrical installation.
can use 400mm THW,RHW,RUH (rating: 400mm = 388amperes)
For a cooker oven with a maximum of 2600 watts, a 2.5mm cable is recommended to handle the load safely. This size of cable is commonly used for appliances with this power rating and will ensure that the electrical supply is properly distributed without overheating the cable. Be sure to consult a qualified electrician for installation to ensure safety and compliance with wiring regulations.
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.
