Electrical Cable Size | Australia

While safety prevents overheating, voltage drop ensures equipment works correctly. Over long distances—such as a shed fed by a 50-metre cable from a house—the resistance of the wire reduces the voltage reaching the appliance. If voltage drops too low (below 5% of nominal 230V, or approximately 218V), motors may stall, lights may dim, and equipment may overheat.
