Induction motor comprised inductor as the most part in it and an inductor has the characteristic to oppose the change of current, i.e., it has lagging power factor as current lags behind the voltage. Hence, an induction motor works on lagging power factor.
It depends on the power factor. One horsepower is defined as 746 watts. If the power factor were unity, then one horsepower would be 0.746 kva. Since electric motors are inductive, they have a less than unity power factor, so the actual kva would be somewhat higher, but the exact value depends...
A transformer is going to have a kva rating on the nameplate. Divide this number by the voltage of the primary or secondary and you get the amp capacity of the primary or secondary respectively. Do not use the voltage of the primary to determine the amp capacity of the secondary, or vice versa.

Without studying electrical engineering material you will be hard pressed to answer any questions pertaining to the subject.
As are most current carrying components in a control panel, they are protected from grounding out by having insulation wrapped around them.
This requires care because 415 v is usually a three-phase supply,  while 230 v is usually single-phase. A 415 v three-phase has a line  to neutral voltage of 240 v so a transformer might not be  necessary.   The number of turns depend on the size of the magnetic core, a  larger core requires...
Normally current carrying capacity tends to the maximum current withstanding capacity for the particular cable which is considered under to be designed. It depends on how you are laying the cable i.e., in open air, duct, or burried and the type of the conductor used in the cable i.e., aluminium or...
