Voltage drop

Power cables consist of reactance and resistance. Thus the current flowing through these power cables would undoubtedly cause a drop in the voltage. But this voltage drop should never affect the loads that the connected by the power cables. Thus, before buying power cable accessories India, one should watch out for the voltage drop in both the steady state as well as for the acceleration state for any large loads.
