Answer Posted / dinesh kakatkar
for the control of any circui few amperes of current is
required so normally we use a small cross-sectional wires.
This current can be mA to Few Ampers and risk of FAULT
current flowing is less and normally a single phase so we
require a small cable of 2 core or 3 core or less cross-
section.
The power cables is used depending on the application in
the Amperes to KA and the FAULT current is more and in the
range of KA.So the application of this cable is to supply a
several Ampere of current and Voltage ranging from the 230
V to Several KV depending on the load.So this cable is
called power cable as it is used to feed power.
Even based upon the application the cables are called as
Power and Control Cables.
