Engineers and electricians do not guess cable sizes; they rely on standardized codes such as the IEC (International Electrotechnical Commission) standards, the NEC (National Electrical Code) in the US, or the IET Wiring Regulations (BS 7671) in the UK.

Long cables act like resistors. Voltage drops along the length, so your appliance gets less than 230V (or 120V). This wastes power and can damage motors. cable sizes
