Answer / Monika Deora

The connecting cables for a 90kW motor should be selected based on factors such as voltage, current, and power factor. The correct formula for calculating the required cross-sectional area (A) of the cable conductor is given by A = P/V^2 * kpf. Here, P is the power in watts, V is the voltage, and kpf is the correction factor for power factor (usually between 1 and 1.4).
