Normal power is the multiplication of current to combination of resistive and reactive or capacitive load. From the vector sum of Apparent power minus real power we can get reactive power(KVAr), which is basically lagging power due to reactive load. This will be the exact rating of capacitor bank. You can find it by cos $ of apparent power.
Adding a capacitor bank makes absolutely no difference whatsoever to the amount of energy consumed (in kilowatt hours). The capacitor bank might reduce the load current, but this does not affect the amount of energy consumed. Anyone who tries to sell you a 'capacitor bank' in order to save you energy is selling a SCAM!

It depends upon at how much voltage level 400 kvar capacitor bank is used.
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.
Capacitor banks can improve the power factor if the load is leading, which is unusual. Typically in substations capacitor banks are employed to reduce over voltage.

You need to explain what you mean by '4 mb'.
It is calculated by knowing what the reactive power is that has to be countered.See related links below.

how to calculate the powerfactor in capacitor
The formula to calculate the maximum charge on a capacitor in an electrical circuit is Q CV, where Q represents the charge on the capacitor, C is the capacitance of the capacitor, and V is the voltage across the capacitor.
To calculate the potential difference across a capacitor, you can use the formula V Q/C, where V is the potential difference, Q is the charge stored on the capacitor, and C is the capacitance of the capacitor.
Series reactors may be used in switching in capacitor banks. These are used to minimize the transient voltage spikes on the system resulting from switching in a capacitor bank.
The primary reason for a capacitor bank in an electrical substation is for power factor correction. There may also be some secondary purpose for the capacitor bank but the primary reason is power factor correction.

To calculate the charge on each capacitor in the circuit, you can use the formula Q CV, where Q is the charge, C is the capacitance of the capacitor, and V is the voltage across the capacitor. Simply plug in the values for capacitance and voltage for each capacitor in the circuit to find the charge on each one.
