A 300/300 Voltage rating indicates that the cord is suitable for operation at 300 Volts to earth or between conductors. Cords to this rating are intended for single phase domestic systems, light duty only. A 300/500 voltage rating indicates that the cord is suitable for operations at 300 Volts to earth or 500 Volts between conductors. The cords are sheathed and suitable for single and three phase supplied for general domestic and industrial duties.
During manufacture, all cores are individually spark tested at between 4 and 6 kV depending upon conductor size. Single core cables are selected on a random basis, other cables on a 100% basis and subject to a voltage withstand test for a period of five minutes
